Hard to believe that I have never had SWU that did not clear....until now- for a JFK-LHR flight I booked back in April and put the upg req in then as well. Now a week out and it is J0 and seat map on EF shows a nearly full cabin. Oddly my two favorite EXP agents are saying the SWU will most probably not clear So how bad WILL 31J actually be? and any other tips for flying across the pond in the back? EF is showing most classes in Y on the flight as 7 and seat maps are all showing several rows of center seats completely open - how do the FA in the back work folks trying to move to open rows? Thanks!
