Most important tips

Know before you go

A compact traveler cheat sheet for timing, terminals, food, and disruption checks.

Timing

Arrive 2 hours early for domestic

Security averages 15-30 min; add buffer for Terminal D international.

Peak mornings and evenings see longer lines at A/C.

Terminal

Use the train for connections

Subway train links all terminals landside; airside connections via moving walkways in C/E.

Avoid walking between A and E without the train.

Food

Grab at Terminal C before security

Better variety landside; airside options limited to chains.

United Clubs provide free snacks if eligible.

Status

United Gold gets Club access

Star Alliance Gold or United Club card unlocks multiple locations.

Centurion requires Amex Platinum and 3-hour rule for non-layovers.
