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. Metro Rail does not yet enter the airport directly — the K Line shuttle and FlyAway bus to Union Station are the rail-adjacent options. American, Delta, United, Southwest and Alaska all run major operations here; international long-haul fills T2 and the Tom Bradley International Terminal.
Arriving in Denver
Denver International is 25 miles northeast of downtown Denver — the most remote big-city airport in the US, deliberately sited to allow for unlimited expansion. The University of Colorado A Line commuter train runs from a dedicated station every 15 minutes to Union Station in 37 minutes for $10.50. Snow can disrupt operations from November through April; Denver fares are cheapest in shoulder seasons (April–May, September–October).
