airlines will no longer be able to market and sell tickets with their names and designator codes on Mexican-operated flights. While the new rating allows Mexican air carriers to continue existing service to the United States, it prohibits any new service and routes. And given that AeroMexico is, y’know, a Mexican airline (in a joint venture with Delta), people are understandably nervous about what this all means. Some Delta SkyMiles members rely on AeroMexico mileage runs to help them rack up MQD and MQM. We’ve received plenty of comments, emails, Tweets, social media DMs, and homing pigeon messages since the FAA downgraded Mexico’s safety rating from Category 1 to Category 2.
