When does the waitlist for a international SWU clear? Currently Gold and I am booked IAD-PHL-LGW and was waitlisted to use my SWU for the entire trip. Flight is next Thursday--Seat maps look good (18 open out-17 open on the return)--I know this maybe off by a few but my chances look good-- When do you think I should call back to see if they open seats up?
