US Transportation Secretary Sean Duffy revoked the antitrust immunity of Delta and Aeromexico's partnership, citing unfair practices by Mexico. Mexico's redirection of flights to a less accessible airport, Felipe Angeles International Airport, is deemed disadvantageous to US airlines. Duffy argues this violates trade agreements, impacting US airlines' competitiveness. Delta and Aeromexico, while disappointed, will continue to cooperate but with reduced integration. The decision, effective January, is expected to negatively affect US-Mexico travel and economies, prompting potential legal challenges.
