Two of my friends will be travelling on the 788 on YYZ-LHR in WT. One friend is disabled required full assistance i.e. assistance getting onboard, onboard wheelchair to seat and use of it to get around the aircraft (Category 3). I'm trying to choose good seats for them. I noticed that 30D/F would probably be fine. It is close to the lav and it seems like E is blocked right now as all the bassinet seats seem to be blocked right in front of them. Of course this may change at the airport but in their experience it will be blocked for them because any pax thinking of seat swapping with 30 D/F will be out of luck. These do not count as the exit row being in the centre block.

The only thing that concerns me is the armrest are presumably fixed and they are quite big guys. Do you think these seats are a good choice?
