Flying from Los Angeles International
Los Angeles International spreads across nine terminals arranged in a U around the central hub, with the inter-terminal LAX-it shuttle and the new Automated People Mover (opening late 2026) connecting them.

American, Delta, United, Southwest and Alaska all run major operations here; international long-haul fills T2 and the Tom Bradley International Terminal.
Arriving in Chicago
