Delta and Aeroméxico commonly operate nonstop flights between John F. Kennedy International Airport (JFK) and Mexico City International Airport (MEX). Delta typically offers SkyMiles loyalty perks, complimentary snacks on short-haul international flights, and optional seat-bundle upgrades; Aeroméxico provides full-service offerings, SkyTeam connections, and often competitive fares on nonstop timetables. Baggage allowances vary by fare class—compare base economy vs. bundled fares when booking. For February travel, check both carriers’ flexible-change policies and compare total trip time, checked bag fees, and onboard amenities before you buy.
