ORD's clear standout if your ticket grants entry: arrive early enough to eat and shower.

Convenient because there are three locations, but the standard Admirals Club experience is functional rather than memorable.

American’s premium T3 room at Concourse H/K. Official hours 4:15 a.m.–10:45 p.m. Not a standard oneworld Sapphire or Admirals Club membership room.

A useful Terminal 5 refuge for eligible Delta and SkyTeam travelers, especially because the terminal otherwise has few broadly accessible options.

A compact airline lounge that is most useful when departing on LOT; expectations should be modest.

Basic T5 contract lounge. Live Priority Pass lists 07:00–00:00, 3-hour max stay, and capacity restrictions especially 15:00–20:30. Follow the live PP map (M13 / across from Delta).

Second Priority Pass soft lounge in T5. Live PP lists 09:00–22:00 near Gate M19 with a 3-hour max stay. Midday fallback when Air France blocks cardholders.
