A genuine premium room with showers and a terrace, but only for listed premium-cabin passengers. Official hours 08:00–21:30 daily — ignore older weekday-split listings.

The original A1 Sky Club. Use it when it is closer than A11 or when A11 has not opened yet for the day. Sky Club credentials do not get you into Delta One.

The newer A11 Sky Club is the better general Delta room. Showers are in the Delta One Lounge above, not in this club.

The live Priority Pass door on Concourse A. Fine when it has seats; skip it when the queue is out the door and you have a short walk to the gate.

Straightforward United/Star room on the A mezzanine. No reason to detour from C, D, N, or S for it.

The C-gate Alaska room closes at 19:00. Do not plan an evening departure around it. No showers here.

The convenient Alaska room if you used Checkpoint 4. Open until 23:00, unlike the C location. No showers.

The oneworld room for the London bank. Hours follow BA’s Seattle operation, not a full airport day. Not Priority Pass.

The Priority Pass room that actually sits on the S-gate bank. Showers are here, not in the A location. It still fills before Europe and Asia departures.
