After having my end of March 2019 morning LHR to IAH 787 changed to 12F 777 I’ve looked and I’m not going to benefit from this change to 747 on the return
Reward booking in CW. Deciding whether to change to the 4pm from the 8pm return flight to finally get a chance to sit on the upper deck. Knowing my luck with this booking there’ll be another aircraft change if I do that.
