American Airlines and Mexicana de Aviacion began codesharing on each other’s flights between the United States and Mexico, the first phase of a wide-ranging codesharing arrangement.

In this first phase, American and Mexicana are placing their codes on each other’s nonstop trans-border flights between the United States and Mexico. The two carriers currently serve a total of 53 nonstop trans-border markets.

In subsequent phases, American will place its code on Mexicana’s connecting flights within Mexico to destinations such as Huatulco, Merida, Oaxaca, Tampico and Veracruz. Mexicana, for its part, will place its code on American’s flights connecting from Mexicana’s U.S. gateways to markets within the U.S., as well as to points beyond the United States served by American.

In addition to the codesharing, American and Mexicana have also implemented a reciprocal frequent flyer arrangement that enables members of both programs to accrue and redeem miles in American’s AAdvantage or Mexicana’s Frecuenta program.
