American departs from Terminal 4 at Los Angeles International Airport (LAX). We verified this against the airport's own sources on June 27, 2026 — airlines do move terminals, so we date every check.

American departs from Terminal 4 at Los Angeles International Airport (LAX). Mainline check-in, ticketing, and TSA screening at Terminal 4. Terminal 5 (formerly the other AA terminal) closed permanently for demolition/rebuild on Oct 28, 2025. An airside tunnel links T4 to T6-T8; a Level 5 secure connector links T4 to TBIT. American Eagle regional flights use the satellite 'Regional Terminal' (gates 52A-52I) east of T8, reached by an airside shuttle from Terminal 4. Verified June 27, 2026.
Check-in at Terminal 4 (all domestic and international). Bag drop usually closes 45 minutes before departure, so build that into your morning.
American consolidated all LAX operations into Terminal 4 (plus TBIT for some international) when Terminal 5 closed for demolition on Oct 28, 2025. We confirmed American's current Terminal 4 on June 27, 2026.
International arrivals processed at Tom Bradley (TBIT); some AA international departures board from TBIT, but those passengers check in and clear security at Terminal 4.
