Allegiant air raises concerns about Mexican government's transparency on flight operations

Allegiant Air, a U.S. carrier, has voiced apprehension over the Mexican government's transparency regarding flight operations in Mexico City.

Regulators did not specify what those actions were, but Mexican officials had speculated that a government decree requiring cargo flights be moved out of the hub was behind the friction.

Mexico earlier this year ordered that cargo lines stop operating at the AICM, instead pushing them to move operations to the military-run Felipe Angeles International Airport (AIFA) north of Mexico City.

Mexico extended the deadline for carriers to make the move to September after a request from U.S. Transportation Secretary Pete Buttigieg on behalf of concerned U.S. airlines, according to Mexican officials.
