US Airport Lounges lists 279 lounges at the 30 busiest US airports, each with its terminal, hours where published, and the cards, memberships or status that get you in.
Every lounge carries a source link and a check date. Entries we could not confirm are clearly marked as unverified.
Access tags follow each lounge brand's published rules. Priority Pass is only tagged where the source lists it, and day-pass prices only appear where the operator publishes them.
