It's been a couple of years since I last used it (back when I flew AC and not UA), but it is a full serve GoodLife. Filled with lots of cardio, racks, machines, etc. that you would find at any GoodLife. The 15 minute circuit, tvs over cardio machines, etc., With locker room and showers.

They'll hold your luggage for a specific amount of time (used to be 2 hours), by tagging it when you enter. Used to be told that security did hourly checks of the baggage, to make sure no baggage was being stored.long term.

As with your plans, I used to enjoy using it when I had a long layover.
