Starting on Jan. 1, 2016, there will no longer be restrictions on the number of airlines servicing city pairs between the United States and Mexico.

The U.S. Department of Transportation has announced a revision of the 2005 agreement between the two countries that limited the number of carriers between two cities to two – three if they served some of the major tourist sites, such as Cancun and Cozumel, for instance.

The new agreement with Mexico includes unlimited market access for U.S. and Mexican air carriers, improved intermodal rights, pricing flexibility, and other important commercial rights, according to the DOT.

“Travelers, shippers, airlines, and the economies of both countries will benefit from competitive pricing and more convenient air service,” U.S. Transportation Secretary Anthony Foxx said in a statement. “This agreement is the result of the commitment on both sides of the border to strengthen the strong bonds of trade and tourism between our two countries, and demonstrate our shared commitment to a competitive, market-based international economic system.”

The new agreement will remove the numerical limitations on the number of airlines that may provide passengers service in all U.S.-Mexico city pairs.  As a result, some city-pair markets might see the entrance of new carriers for the first time in years.

None of the major U.S. carriers have announced any plans yet in response to the new agreement.

Cargo airlines will have expanded opportunities to provide service to new destinations that were not available under the current agreement, and to offer services from the United States to Mexico and beyond Mexico to other countries.

The agreement will not enter into force until January 1, 2016, after both parties have completed their necessary internal processes, the DOT said.
