when will the US UC sale begin?

I know the sale is LHR-US but when will it reverse US-LHR? Any ideas?
Thx!

hmmmm, bet is depends on how the ex-LON UCS sale goes. It would be in VS' interest to collect more GBP than USD at this point in time.

hahhaha..yeah, and a poor time for me to think about going!! But, it's an annual pilgramage, just have to save a few, ok alot, of extra pennies
