I flew on the 787 YYC-LHR in CW. Was in 3A, which I found to be wonderful. It had aisle access, without having to step over anyone. Great window views. Best of all, once I put the seat into bed mode and went to sleep, it was like I was in a private cabin. Next flight however is in WT+, and one leg will be on the 787. Will be interesting to see how it is. I have been in WT+ on both the 777, and 767.
