About those mobile lounges.
Certainly, I hate them. You generally wait about 5 minutes to for it to leave (they post time till departure outside the lounge). Then it has to trek across the active taxiways, stopping for aircraft and various other vehicles -- can take a couple minutes or fifteen.
I was sitting next to a UA 777 captain in F on an ORD-IAD flight this morning who told me that in customer surveys the lounges never make the list of complaints -- that if you survey people in the airport, everyone hates 'em, but when filling out surveys people never list the lounges. Grr.
