By this time, American Airlines had changed the requirements to include pressurization and deemed the design too small. Convair used the first prototype for 240 series development work before it had the plane broken up in 1947. To meet the requirements of airlines for a pressurized airliner, Convair produced

171-505: The Vickers Viscount , Convair produced the Model 440 Metropolitan, with more streamlined cowlings, new engine exhausts, and better cabin soundproofing. As the "Super 240" evolved into the CV-340 and CV-440, the design reached the limit of piston-engine performance, and future development centered on conversion to turboprop power. Convair delivered the first production Convairliner to American on February 29, 1948. They delivered

190-420: The " Convairliners " continue to fly in the 21st century. The design began with a requirement by American Airlines for an airliner to replace its Douglas DC-3s .

For a very short time in the spring of 1987, Continental Express operated by Trans Colorado Airlines served the city with flights to Albuquerque and El Paso also using Metroliners. Mesa continued their service until 2007 when they, like their predecessors, grew too large and discontinued serving small cities with small aircraft.
