We are flying rt Dulles/Heathrow on British Airways in mid-March & returning April 2. At the time we made our reservations in early November, BA was offering an outbound upgrade to WT+ for about $150 pp. Of course we booked the outbound upgrade but inbound was much more expensive. I've been watching the price of the WT+ upgrade from Heathrow to Dulles & it's still $698 pp. Yikes! We usually upgrade but certainly not at this price. That's almost what we paid for each economy roundtrip ticket. We've never had this happen before. Has anyone had recent success in booking a reasonably priced WT+ upgrade on British Airways? Thanks.
