From Investing.com:

The U.S. government does not plan to renew the antitrust immunity for Delta Airlines and Aeromexico after the Mexican government made changes at Mexico City International Airport (AICM). Last year, cargo flights were moved to a newer airport, and slot availabilities for commercial flights were reduced, to the dismay of U.S. authorities and carriers. The decision is pending a final ruling, and the immunity agreement will tentatively end on Oct. 26.

The U.S. Department of Transportation (DOT) reported that the Mexican government’s actions negatively impact existing carriers and potential new entrants at the AICM. If the decision is upheld, the joint venture between Delta and Aeromexico, which operates more than 90 daily flights between the countries, will be affected. U.S. authorities have communicated their displeasure to Mexican officials, but Mexico’s transportation ministry has yet to respond.

The Mexican government’s move to boost low traffic at the new Felipe Angeles International Airport has thrown off the plans of other airlines as well. Allegiant and Viva Aerobus had planned to launch a joint venture, but the decision to move cargo flights disrupted these plans. Despite the Mexican government’s explanation that renovations were needed at AICM, the DOT has been informed that no additional capacity will be added for the time being. The DOT has called the decisions “fundamentally out of compliance with the existing bilateral air service agreement and international norms.”
