It's not the seat map - I called UA reservations and they told me E+ was full. Best they could get me was 21F.

My upgrade hopes are for the 747... I long ago wrote off any hopes of upgrade on the 757 because I'm sure there's more than 24 1Ks on the flight, let alone paid-F, to get down to my lowly US Gold status

Edit: Eep, F1 C0? Ouch. Guess I'm stuck way way way in the back with this one... or I'll start prayin' to the oversold god

Thanks for the answers
