I'll be flying to SFO in August. I'm a 1P and will be traveling with my fiance. Just trying to figure out what flights might have the best UDU opportunity. I know, I know, YMMV. But generally, is it easier to get an upgrade out of IAD or BWI for the nonstops? It looks as if there's a int'l 777 flying on Thursday evening - how's that upgrade? Thanks to everyone ahead of time!
