American Airlines will begin service on its new Airbus A319s between Dallas-Fort Worth and four cities from 16 September.
Charlotte, Cleveland, Memphis and Wichita are the initial destinations with additional cities being added through the fourth quarter as the Fort Worth-based carrier takes delivery of more aircraft. The aircraft will be used to replace other jets on existing flights.
A319 flights from Dallas-Fort Worth to Dayton and Lubbock will begin on 1 October; to El Paso, Huntsville, McAllen and Toronto from 14 October; to San Salvador from 1 November; and to Crested Butte, Jackson Hole and Vail from 19 December, says American.
The Oneworld alliance member will have roughly six A319s in its fleet in September and plans to have 15 by the end of the year, it says.
American has orders for 130 A319s and A321s, which is split equally according to engine manufacturer International Aero Engines (IAE).
However, the airline says that it is "still evaluating how many of each variant" that it will take.
