The downgrade of Mexico is a limitation for Mexican airlines. As a result, they can neither increase frequencies, nor add routes, nor change equipment. And as the forecast is that it will be a good summer, in relation to the demand, the American airlines take advantage. Then, American Airlines will add 11 new routes.
In the same way, American Airlines will increase its offer to Mexico in the summer, with 11 new routes. As of June 3, the Dallas-Ft. Worth Airport (DFW) to Hermosillo. On June 5 it was the turn of Los Angeles / Cancun. DFW flights to Mérida (which will operate on Saturdays), Acapulco, Ixtapa-Zihuatanejo, Huatulco, Mérida, and La Paz will also be added; and from this last city Phoenix. To this are added services from Austin to San José del Cabo
