U.S. government officials said the U.S. government downgraded Mexico’s aviation safety rating on Tuesday.

U.S. government officials said the U.S. government downgraded Mexico’s aviation safety rating on Tuesday, a move that banned Aeromexico from adding new U.S. flights and restricted the airline’s ability to implement marketing agreements.

Reuters first reported on Friday the Federal Aviation Administration’s (FAA) downgrade plan.

The US Federal Aviation Administration (FAA) had a lengthy meeting with the Mexican aviation regulator about its concerns. It is expected to be officially announced in the United States later on Tuesday.

Mexican President Andres Manuel Lopez Obrador said on Monday that the US authorities should not downgrade Mexico’s air safety title on the grounds that Mexico complies with all relevant regulations.

“We have been complying with all requirements. When asked about the possibility of the United States lowering the security level, Lopez Obrador said at a regular press conference: “We believe that this should not be done. One decision. “

Downgrading Mexico from “Category 1” to “Category 2” means that Aeromexico’s current services in the United States will not be affected, but they will not be able to launch new flights or conduct inter-airline marketing practices?? , For example, the sale of seat arrangements for each other’s flights through code sharing will be restricted.

Delta Air Lines said on Tuesday that the FAA downgrade has nothing to do with partner Aeromexico and has little impact on customers.

“This has nothing to do with Aeromexico. This is about the Mexican version of the FAA without proper agreement,” Delta President Glen Hauenstein said at the Wolf Research Conference.

Delta Air Lines and Aeromexico have reached a code-sharing arrangement that allows the two airlines to sell seats on each other’s flights.

Hauenstein added that after downgrading, Delta Air Lines will be forced to delete its code on Aeromexico flights, although Aeromexico may continue to code on Delta flights, while Delta loyalty program members can still use the code on flights that normally carry the code.

This is not the first time the FAA has downgraded Mexico’s aviation safety rating. In 2010, the agency downgraded Mexico’s rating due to suspicion of deficiencies in its Civil Aviation Administration, and then restored the highest rating four months later.
