Stuck in Terminal 4 during a flight delay this past weekend and spent some time in both lounges when the time got pushed back further.

The Holideck second floor remains closed. Only the main floor and the small, cold (but fun for airplane buffs) observation area are open. No indication that any work is proceeding in a rush on the second floor. The lounge as a whole is very tired and could use a refresh, yet certainly adequate with seating in several areas; efficient staff; a good selection of beverages; and a so-so selection of primarily packaged snacks. Entry is via a range of affiliations including Priority Pass or one-time bookings through Holiday Extras (18 to 19 pounds).

The SkyTeam Lounge is much newer, nicer and busier. No questions or hassles using Continental credentials; however both Presidents Club and BusinessFirst entry preclude guests, presumably because Continental is paying its old alliance per admission.
