Aeromexico and Delta Air Lines plan to launch new flights between Cancun and both Dallas-Fort Worth and Houston Intercontinental, jumping on routes dominated by competitors American Airlines and United Airlines.
The Mexican carrier would operate the new daily flights with Boeing 737 aircraft from July, according to a US Department of Transportation (DOT) motion approving the flights today. They would carry Delta's code under the airlines' existing codeshare agreement.
American, Spirit Airlines and Sun Country Airlines fly between Cancun and Dallas-Fort Worth, while only United flies between Cancun and Houston, Innovata schedules show.
Dallas is a hub for American and Houston a hub for United.
Delta has said that they are interested in increasing service to Mexico. However, a recent Flightglobal analysis found that the airline's available seat kilometres (ASKs) to the country were down 16.4% in April compared to the same month in 2010.
Combined Aeromexico and Delta capacity was down 15% the same month compared to the five-year peak in April 2011.
Delta and its regional partners ExpressJet Airlines and SkyWest Airlines are seeking approval for a new Atlanta-Leon/Guanajuato daily flight that would begin in December.
