Hey -- thanks for all the replies. I ended up booking flights following Lurker's suggestion but when I called US to see if I could fly stand-by on an earlier flight to CLT they said that if I were to take the earlier flight causing my time in CLT to go above 4 hrs, they may end up re-pricing my whole itinerary which they know I'd never go for, essentially forcing me to stick w/ my orig flights. Do you really think they’d reprice my itinerary or confirm me on an earlier flight to DCA outta CLT and go that far just so I don’t exceed 4 hrs? I’ve booked the ticket but since it’s at usairways.com I still have time to scrap it and sched new flights. Thanks
