I used the Senator Lounge last night - it gets very busy with Eurowings, Austrian and Lufthana's flights. Food was OK, service fine.
The TSA is shockingly bad - Priority Line only until you get to ID checkers when it's just one line. Three machines open, but took about 45 minutes to get through on Saturday evening.
No Pre-Check just keep on shoes and use metal detector.
Flight left late from gate 68.
