I know it's a 'waste' but headed to London Sunday, and have DTW-LHR waitlisted for GUC (short flight, but can't sleep in coach).

Return LHR-MSP was able to use another GUC. Cleared right away. I actually would have been fine w/ C+, but I bought ticket about 5 days ago, no C+ left either direction.

And customer/prospect changed agenda, so I have a meeting a few hours after I arrive. So I really hope I can get some sleep - and GUC clears.

Work travel is so awesome
