64-511: Portland International Jetport ( IATA : PWM , ICAO : KPWM , FAA LID : PWM ) is a public airport two miles (3 km) west of downtown Portland , Maine , United States. It is owned and operated by the City of Portland. A portion of the Jetport's property, including the main runway, is located within the neighboring city of South Portland . PWM covers 726 acres (293 ha) of land. The airport

128-412: A daily flight to Atlanta on a McDonnell Douglas MD-88 . A regional startup , New England Air Transport (NEAT) began intrastate air service, flying three times weekly to Aroostook County with a Piper Chieftain . This was the first intrastate service offered out of Portland in more than a decade. With these increases, 2008 also saw a number of losses of service, with air traffic in an overall decline as

192-467: A fifth flight to New York City , further increasing the number of available low-cost seats. On September 26, 2007, JetBlue announced a daily direct flight to Orlando , using its Embraer 190 , beginning in January 2008. The year 2007 was a record high for Portland, as the added service posted a 17% increase in passengers from the year before. In 2008, Delta Air Lines resumed mainline service to Portland,

256-482: A market forces down the price of competing tickets. On June 7, 2007, AirTran Airways began seasonal service to Baltimore , and to Orlando . AirTran was the second low-cost carrier in Portland, competing with JetBlue. This was Portland's first scheduled non-stop flight to Florida. AirTran served the Jetport with Boeing 717s and 737s . At the same time as AirTran's arrival, JetBlue announced that it would be adding

320-567: A new airport is built, replacing the old one, leaving the city's new "major" airport (or the only remaining airport) code to no longer correspond with the city's name. The original airport in Nashville, Tennessee, was built in 1936 as part of the Works Progress Administration and called Berry Field with the designation, BNA. A new facility known as Nashville International Airport was built in 1987 but still uses BNA. This

384-435: A new taxiway, A4. This project required systemically closing portions of the main taxiway, removing the existing pavement, lighting, and electrical equipment and replacing the old style taxiway edge lights with less expensive reflectors, adding new taxiway centerline lights embedded into the new pavement, and then finally repaving and painting the section. These closures resulting in a temporary decrease in airport capacity due to

448-456: A number of new routes out of Toronto , Canada including a flight to Portland. The twice-daily Portland-Toronto service began on May 17, 2010, operated by Air Georgian using Beechcraft 1900 D aircraft. Air Canada pulled out of Portland on March 1, 2013, once again leaving PWM without scheduled international service. The Jetport began construction on its expanded terminal as well as several infrastructure improvements in 2010. Major expansion of

512-501: A public outcry and a request from Muskie to restore the original name. People Express Airlines arrived in 1983, the first jet competitor to Northeast/Delta at PWM. The airline, the first low-cost carrier at the Jetport, was known for rock-bottom prices. The airline flew between Portland and Newark , still operated today by United Airlines , who merged with Continental Airlines , which had bought People Express in 1987. In June 1983 United Airlines arrived in Portland, planning to be

576-409: A terminal-building improvement project was undertaken to add two second-level boarding gates, as well as additional space for ticketing, operations, departure lounge, concessions, and an international customs facility. On the morning of September 11, 2001, Mohamed Atta and Abdulaziz al-Omari traveled on Colgan Air Flight 5930 from Portland Jetport to Boston's Logan International Airport. At Logan,

640-420: Is 5,001 by 150 feet (1,524 x 46 m) and 8/26 is 2,703 by 75 feet (824 x 23 m). For the 12-month period ending August 11, 2016, the airport had 24,500 aircraft operations, an average of 67 per day: 69% general aviation , 22% air taxi , and 6% military . In April 2018, 37 aircraft were based at this airport: 31 single- engine and 6 multi-engine. The airport was originally developed under a New Deal project by

704-509: Is GSN and its IATA code is SPN, and some coincide with IATA codes of non-U.S. airports. Canada's unusual codes—which bear little to no similarity with any conventional abbreviation to the city's name—such as YUL in Montréal , and YYZ in Toronto , originated from the two-letter codes used to identify weather reporting stations in the 1930s. The letters preceding the two-letter code follow

768-562: Is a public use airport located one  nautical mile (2  km ) west of the central business district of the state capital of Augusta , a city in Kennebec County, Maine , United States. The airport is owned by the state of Maine, but managed and operated by the city of Augusta. It is served by one commercial airline, with scheduled passenger service subsidized by the Essential Air Service program. As per

832-617: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and

896-523: Is different from the name in English, yet the airport code represents only the English name. Examples include: Due to scarcity of codes, some airports are given codes with letters not found in their names: The use of 'X' as a filler letter is a practice to create three-letter identifiers when more straightforward options were unavailable: Some airports in the United States retained their NWS ( National Weather Service ) codes and simply appended an X at

960-671: Is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal , Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain railway stations. Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes , shared in agreements between airlines and rail lines such as Amtrak , SNCF , and Deutsche Bahn ,

1024-513: Is in conjunction to rules aimed to avoid confusion that seem to apply in the United States, which state that "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." Thus, Washington, D.C. area's three airports all have radically different codes: IAD for Washington–Dulles , DCA for Washington–Reagan (District of Columbia Airport), and BWI for Baltimore (Baltimore–Washington International, formerly BAL). Since HOU

1088-743: Is no other information about the airline other than one timetable. Jet flights began in 1968 and, for the first time, Portland got a non-stop beyond Boston when Northeast DC-9s flew to LaGuardia Airport in New York City . Northeast would be alone at the airport until 1970, when Aroostook Airways began flights between Presque Isle and Portland, with stops in Augusta and Bangor . This airline too faded into obscurity, lasting until 1972. That year, regional Air New England began service in Portland, competing with Northeast Airlines intrastate and between Portland and Boston. In 1972, Northeast Airlines

1152-543: Is not followed outside the United States: In addition, since three letter codes starting with Q are widely used in radio communication, cities whose name begins with "Q" also had to find alternate codes, as in the case of: IATA codes should not be confused with the FAA identifiers of U.S. airports. Most FAA identifiers agree with the corresponding IATA codes, but some do not, such as Saipan , whose FAA identifier

1216-475: Is the busiest in the state. In 2018, the jetport handled more than two million passengers for the first time, breaking the previous record of 1.86 million set in 2017. The Jetport has benefited from service by low-cost carriers such as Southwest Airlines and JetBlue , as well as Portland's increased popularity as a tourist destination. A survey conducted in June 2011 found PWM to be the most affordable airport in

1280-416: Is used for William P. Hobby Airport , the new Houston–Intercontinental became IAH. The code BKK was originally assigned to Bangkok–Don Mueang and was later transferred to Suvarnabhumi Airport , while the former adopted DMK. The code ISK was originally assigned to Gandhinagar Airport (Nashik's old airport) and later on transferred to Ozar Airport (Nashik's current airport). Shanghai–Hongqiao retained

1344-571: The Canadian transcontinental railroads were built, each station was assigned its own two-letter Morse code : When the Canadian government established airports, it used the existing railway codes for them as well. If the airport had a weather station, authorities added a "Y" to the front of the code, meaning "Yes" to indicate it had a weather station or some other letter to indicate it did not. When international codes were created in cooperation with

It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a non-primary commercial service facility. Augusta State Airport covers an area of 406 acres (164 ha ) at an elevation of 352 feet (107 m) above mean sea level . It has two asphalt -paved runways : 17/35

1472-850: The Portland Transportation Center . There are four small airports within ten nautical miles of the Jetport. Clockwise from the north, they are: Eric's Field (78ME) in Falmouth , Scarborough , Super Cub Field (ME26) in Westbrook , and Webster Field (ME91) in Gorham . The nearest airports with flight procedures are: Biddeford Municipal (B19) (13 nautical miles southwest), Brunswick Executive (KBXM) (22 nm northeast), Sanford Regional (KSFM) (23 nm southwest) and Auburn–Lewiston Municipal (KLEW) (24 nm north).

1536-542: The Jetport in 1986, flying a route from Portland to Washington's Dulles International Airport . This would be short-lived, however, as Presidential Airways ceased operations by the end of the decade. 1987 saw the arrival of Continental Airlines when the airline bought People Express and took over their routes. It saw the beginning of Business Express , a commuter airline offering service from Portland to Boston, New York–La Guardia, and Presque Isle, originally independently, and then doing business as Delta Connection. In 1995

1600-460: The Jetport. In 2004, Runway 11/29 was lengthened to 7,200 feet (2,195 m). On September 1, 2005, Delta Air Lines ended mainline service to PWM. Despite the airline's strong history at Portland, serving the Jetport with aircraft as large as the Boeing 727 and 757 , Delta briefly downgraded flights subcontracting to smaller aircraft operated by Delta Connection on Bombardier CRJ series . In

1664-613: The Maine Emergency Relief Administration, the state division of the Federal Emergency Relief Administration in a statewide survey of airports by Capt. Harry M. Jones in January 1934. The airport was built with one north-south 2,000x80’ gravel runway, one east-west 1,600x80’ gravel runway, and one northeast-southwest 2,500x80’ gravel runway. Runway 17/35 was reconstructed in the summer of 2012. The original surface

Bus Route #5 travels to and from the Portland Jetport into downtown Portland with connections to other METRO routes, Amtrak, South Portland Bus and ZOOM (with connections to Biddeford , Saco and Old Orchard Beach ). A shuttle bus service called The Portland Explorer provides access to area hotels and to other local transportation, such as the Amtrak Downeaster train service and Concord Coach Lines intercity bus service at

1792-500: The September 11, 2001, terrorist attacks, plane spotters observed Jetport activity from Jetport Plaza Road and Jetport Access Road, but such activity was subsequently prohibited in the wake of the attacks due to security concerns. The official plane-spotting area includes a sign depicting some of the passenger aircraft typically seen at the Jetport. In 2010 Starlink Aviation ended its service to Yarmouth and Halifax, Nova Scotia, citing

1856-510: The U.S. For example, several airports in Alaska have scheduled commercial service, such as Stebbins and Nanwalek , which use FAA codes instead of ICAO codes. Thus, neither system completely includes all airports with scheduled service. Some airports are identified in colloquial speech by their IATA code. Examples include LAX and JFK . Augusta State Airport Augusta State Airport ( IATA : AUG , ICAO : KAUG , FAA LID : AUG )

1920-481: The United States, because "Y" was seldom used in the United States, Canada simply used the weather station codes for its airports, changing the "Y" to a "Z" if it conflicted with an airport code already in use. The result is that most major Canadian airport codes start with "Y" followed by two letters in the city's name (for example, YOW for O tta w a , YWG for W innipe g , YYC for C algar y , or YVR for V ancouve r ), whereas other Canadian airports append

1984-459: The Works Progress Administration (WPA) built Portland's first real terminal, a brick structure that is now the general-aviation terminal. According to Portland Town Reports, the WPA conducted two projects sponsored by the city: The present airport started to take shape in the 1950s. The March 1951 chart shows runway 1 4260 ft long, runway 10 2900 ft, and runway 15 4010 ft. Runway 11/29

2048-745: The airline industry scaled back due to the Great Recession . In 2020 Delta retired their MD-88s, now using the A319 to Atlanta. At the onset of 2009, international service resumed. Starlink Aviation announced service between Portland and Halifax, Nova Scotia and Yarmouth, Nova Scotia to begin in February of that year. In fall 2009, PWM built an official plane spotting area on Aviation Boulevard in South Portland, allowing aircraft enthusiasts to observe flights arriving and departing. Prior to

2112-441: The airline terminal – which had already been expanded at least twice – took place throughout 2010 and 2011. The expanded terminal opened to the public on October 2, 2011. The $ 75 million project, designed by Gensler and built by Turner Construction , brought a number of changes, including improvements to the check-in areas and security, reconfiguration of the airport access road and terminal roads, and rehabilitation and expansion of

2176-440: The airport itself instead of the city it serves, while another code is reserved which refers to the city itself which can be used to search for flights to any of its airports. For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,

2240-402: The airport received its first commercial service on August 1, 1931, when Boston-Maine Airways began a flight from Portland to Boston . In 1937 the city of Portland purchased the airfield for $ 68,471 and changed its name to Portland-Westbrook Municipal Airport ; this is the origin of its airport code, PWM. "Westbrook" referred to the location of the last directional light before the airport in

2304-596: The airport's deicing facilities, and lengthening Runway 18/36. A survey conducted in June 2011 by travel website Cheapflights found PWM to be an affordable airport in the region compared to Manchester , Bangor , and Logan , and the third most affordable in New England (behind Bradley and T. F. Green ). Starting in April 2024 the Jetport began a construction project to upgrade the taxiway lights along Taxiway A, eliminating Taxiways D and E, and construction of

2368-418: The airport's former name, such as Orlando International Airport 's MCO (for Mc C o y Air Force Base), or Chicago's O'Hare International Airport , which is coded ORD for its original name: Or char d Field. In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after

2432-502: The code SHA, while the newer Shanghai–Pudong adopted PVG. The opposite was true for Berlin : the airport Berlin–Tegel used the code TXL, while its smaller counterpart Berlin–Schönefeld used SXF; the Berlin Brandenburg Airport has the airport code BER, which is also part of its branding. The airports of Hamburg (HAM) and Hannover (HAJ) are less than 100 nautical miles (190 km) apart and therefore share

2496-610: The duo, along with 3 other hijackers boarded American Airlines Flight 11 , leaving Boston for Los Angeles. Approximately 15 minutes after the plane departed Logan, the hijackers took control of the plane and flew it into the North Tower of the World Trade Center . In the wake of the attacks, many U.S. airlines cut flights. This furthered the airlines' shift from mainline jets to smaller regional jets or turboprops at PWM. In late 2002 American Eagle stopped flying to

2560-934: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots. In the US, such airfields use FAA codes instead of ICAO. There are airports with scheduled service for which there are ICAO codes but not IATA codes, such as Nkhotakota Airport/Tangole Airport in Malawi or Chōfu Airport in Tokyo, Japan. There are also several minor airports in Russia (e.g., Omsukchan Airport ) which lack IATA codes and instead use internal Russian codes for booking. Flights to these airports cannot be booked through

2624-557: The first three letters of the city in which it is located, for instance: The code may also be a combination of the letters in its name, such as: Sometimes the airport code reflects pronunciation, rather than spelling, namely: For many reasons, some airport codes do not fit the normal scheme described above. Some airports, for example, cross several municipalities or regions, and therefore, use codes derived from some of their letters, resulting in: Other airports—particularly those serving cities with multiple airports—have codes derived from

2688-478: The following format: Most large airports in Canada have codes that begin with the letter "Y", although not all "Y" codes are Canadian (for example, YUM for Yuma, Arizona , and YNT for Yantai , China), and not all Canadian airports start with the letter "Y" (for example, ZBF for Bathurst, New Brunswick ). Many Canadian airports have a code that starts with W, X or Z, but none of these are major airports. When

2752-597: The form of " YYZ ", a song by the rock band Rush , which utilizes the Morse code signal as a musical motif. Some airports have started using their IATA codes as brand names , such as Calgary International Airport (YYC) and Vancouver International Airport (YVR). Numerous New Zealand airports use codes that contain the letter Z, to distinguish them from similar airport names in other countries. Examples include HLZ for Hamilton , ZQN for Queenstown , and WSZ for Westport . Predominantly, airport codes are named after

2816-487: The international air booking systems or have international luggage transferred there, and thus, they are booked instead through the airline or a domestic booking system. Several heliports in Greenland have 3-letter codes used internally which might be IATA codes for airports in faraway countries. There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in

2880-440: The late 2000s and continuing today, Delta reinstated mainline service at Portland. Some service began to return as the industry's economics improved between 2005 and 2006. The first step up came with the introduction of the low-cost carrier Independence Air in 2005. On May 1, 2005, Independence added a daily flight to Washington Dulles on an Airbus A319 , making them the first carrier to fly an Airbus out of Portland. Portland

2944-584: The loss of a Canadian subsidy. Soon after Starlink ended their service, a Maine-based company, Twin Cities Air Service , began flying between Portland and Yarmouth on a semi-daily basis. This began on March 15, 2010. Twin Cities ceased its scheduled service out of PWM in December 2012 but continues to offer the route on a charter basis. Also in 2010, Air Canada announced that it would be launching

3008-612: The name of the airport itself, for instance: This is also true with some cities with a single airport (even if there is more than one airport in the metropolitan area of said city), such as BDL for Hartford, Connecticut 's B ra dl ey International Airport or Baltimore's BWI, for B altimore/ W ashington I nternational Airport ; however, the latter also serves Washington, D.C. , alongside Dulles International Airport (IAD, for I nternational A irport D ulles) and Ronald Reagan Washington National Airport (DCA, for D istrict of C olumbia A irport). The code also sometimes comes from

3072-710: The nearby city of Westbrook . In January 1934, a statewide airport survey was conducted by Captain Harry M. Jones, of the Maine Emergency Relief Administration (MERA), a state division of the Federal New Deal public works programs launched in November 1933. MERA expended $ 816,376 across the state on labor in airport construction in the period April 1934 to July 1935. Two runways were constructed at Portland Municipal Airport by MERA, one north–south 2,400'x 100' gravel runway and one east–west 1,500'x 100' gravel runway. In

3136-402: The need for aircraft to "back-taxi" around the closed portions of Taxiway A. Along with the improvements to the lighting on Taxiway A, the project also removed two of the taxiways connecting Taxiway A to the main runway 11/29. This was done to adhere to FAA regulations that aim to prevent aircraft from being pushed back onto the runway while leaving the terminal gates. A new taxiway designated A4

3200-416: The one they are located in: Other airport codes are of obscure origin, and each has its own peculiarities: In Asia, codes that do not correspond with their city's names include Niigata 's KIJ , Nanchang 's KHN and Pyongyang 's FNJ . EuroAirport Basel Mulhouse Freiburg , which serves three countries, has three airport codes: BSL, MLH, EAP. Some cities have a name in their respective language which

3264-630: The only airline to serve 50 states. It originally flew the Burlington route that had been left behind by Air Vermont and later flew non-stop to Chicago. That same year, regional Ransome Airlines , doing business as Delta Connection , began a route between Portland and Boston. This ended in 1986 when Ransome was bought by Pan Am and renamed Pan Am Express. 1986 also brought USAir (renamed US Airways , merged with American Airlines ), which began flights to Philadelphia and Pittsburgh . Low-cost carrier Presidential Airways also began service from

3328-471: The parking garage. The new terminal features a geothermal heating and cooling system – the largest of its kind in Maine – which is expected to reduce the Jetport's consumption of heating oil by up to 102,000 gallons per year. Expansion and improvements are also planned or are in-work for the general-aviation ramp, enlarging the cargo ramp and facilities, re-configuring the alignment of taxiways , improving

3392-454: The passenger terminal expanded to the east with the addition of two baggage carousels . The building also expanded to the west by adding three second-level jetways and a holding room. In 1982, PWM got its first non-stop flight beyond New York when Delta tried a 727 to Cincinnati for a year or so. The Portland City Council renamed the Jetport for longtime senator Edmund Muskie in February 1982, but reversed its decision three weeks later after

3456-559: The region, and the third most affordable in New England . In October 2011, PWM completed a $ 75 million renovation and expansion of its terminal to allow more airline service and more amenities for passengers. In 2020, PWM received $ 4.5 million in federal funds to construct a 1,200 ft-long (370 m) taxiway connecting runways. The airfield was founded in the late 1920s by Dr. Clifford "Kip" Strange, who needed space for his JN-4 "Jenny" Biplane . Known as Stroudwater Airport ,

3520-506: The same first and middle letters, indicating that this rule might be followed only in Germany. Many cities retain historical names in their airport codes, even after having undergone an official name/spelling/transliteration change: Some airport codes are based on previous names associated with a present airport, often with a military heritage. These include: Some airports are named for an administrative division or nearby city, rather than

3584-500: The station code of Malton, Mississauga , where it is located). YUL is used for Montréal–Trudeau (UL was the ID code for the beacon in the city of Kirkland , now the location of Montréal–Trudeau). While these codes make it difficult for the public to associate them with a particular Canadian city, some codes have become popular in usage despite their cryptic nature, particularly at the largest airports. Toronto's code has entered pop culture in

3648-569: The summer of 1935, the MERA aviation program had made possible the extension of the Boston-Portland-Augusta-Waterville-Bangor mail service to Bar Harbor , where an airport, Hancock County–Bar Harbor Airport , had been constructed by the MERA. The Portland town report of 1938 reported that the building of the runways and grading of the field were by WPA labor, and the city furnished part of the material. In 1940,

3712-515: The two-letter code of the radio beacons that were the closest to the actual airport, such as YQX in Gander or YXS in Prince George . Four of the ten provincial capital airports in Canada have ended up with codes beginning with YY, including: Canada's largest airport is YYZ for Toronto Pearson (as YTZ was already allocated to Billy Bishop Toronto City Airport , the airport was given

3776-422: The underserved market, JetBlue began air service to Portland on May 23, 2006, with four daily flights to New York–JFK aboard Airbus A320 and Embraer 190 jets. As a result, JetBlue became the second-largest air carrier at the Jetport (in terms of available seats) nearly overnight. This addition of service inspired what is known as The Southwest Effect , where the addition of a large number of low-cost seats in

3840-529: The use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other. Since the U.S. Navy reserved "N" codes, and to prevent confusion with Federal Communications Commission broadcast call signs , which begin with "W" or "K", the airports of certain U.S. cities whose name begins with one of these letters had to adopt "irregular" airport codes: This practice

3904-447: Was bought by Delta Air Lines , which retained its routes to Bangor , Boston , and New York . By 1979, Delta had added Burlington, Vermont . In 1981, Air New England , after serving Portland for eleven years, ceased operations and pulled out of the Jetport. This departure was followed a year later by the arrival of Air Vermont , a regional carrier that flew between Portland and Burlington until expiring about 1983 or 1984. In 1980,

The airport is accessible from Exit 46 of I-95 (the Maine Turnpike ) and Exit 3 of I-295 , in addition to an entrance for local traffic on outer Congress Street . The jetport provides multiple ground ground lots as well as a parking garage . Parking can be pre-paid online. The Greater Portland METRO provides bus service throughout Portland, Westbrook, Falmouth and

4032-410: Was built in 1957 and lengthened to 6,800 feet (2,073 m) in 1966. The current terminal opened in 1968, when jet flights began. Northeast Airlines long had a monopoly on commercial air travel in Portland, dating to its time as Boston-Maine Airways. Another airline emerged in 1962, when Atlantic Airways began service to Boston's Logan International Airport . This competition was short lived; there

4096-580: Was one of the few markets that Independence Air consistently served with its A319s, and at the time of its bankruptcy, Portland was rumored to be one of its few profitable destinations. FedEx Express also began using an Airbus A310 widebody jet on its cargo flights to Memphis later that year. Although the Boeing 757 is primarily used for these flights today, they will occasionally substitute out an A310 in its place. After Independence Air went bankrupt, Portland had no low-cost carrier, causing fares to go up and passenger numbers to decline. Capitalizing on
