Terminal 1
The older, larger terminal by carrier count: Mexico’s budget airlines (Volaris, Viva Aerobús, Magnicharters) and most foreign carriers — American, United, Air France, KLM, Lufthansa, British Airways, Emirates among them — fly from here, per 2023 press coverage of the airline split (worth confirming on your booking, since AICM has reshuffled terminals before). The Camino Real Aeropuerto hotel reaches it by a covered footbridge to Gate B.
Metro Línea 5’s “Terminal Aérea” station is a few minutes’ walk from T1’s main entrance — the only rail line either terminal has, and Línea 5 does not run to T2.
The Aerotrén to T2 is reserved for passengers already in connection (with an e-ticket, boarding pass or reservation code) and flight crews, boarding at Gate 6, 05:00–01:00 daily. Anyone else has two paid options at Gate 7: TETSA’s own buses (cash, every day 05:00–01:00) or Mexico City’s Metrobús, which added a dedicated shuttle to Terminal 2 in August 2026 — check the sign on the unit, since Metrobús also runs a longer citywide route from the same stop.
Lifts serve Gates 2, 4, 5, 7 and 9 of the arrivals concourse plus the intercity bus station and car parks; electric stairs and ramps cover Salas A, B, D, E1, E2 and F1 and the domestic baggage-claim area. Free mini-vehicle transport for pregnant travellers, older adults and passengers with disabilities runs through the national and international departure lounges, and restrooms are open 24 hours with adapted fixtures.
