On 4/25 I flew through DTW and the Sky Club near the far end of the A-terminal, I think A18, was closed early. I didn't find out it was closed until I got to the club's entrance (app doesn't indicate open/closed, just traffic and standing hours). I was planning to grab dinner at the Sky Club and the unexpected closure left me without enough time to hustle back to the center of the terminal to another club before my connecting flight. The signage said temporarily closed, but didn't provide further details.

Does one or more of the DTW Sky Clubs close early if traffic is low, or was this an unusual closure and I'm safe to assume all Sky Clubs will be operating per the hours in the Delta app?

TIA!
