We are booked on MSY - LHR and also the return LHR - MSY in Business Class. In viewing vidoes it appears that if you are sitting in a window seat (1A, 2A, 3A) that you have access to the aisle by walking around the seat and you do not have to cross over the legs of passengers in the aisle seat for that row (1B, 2B, 3B).

We have friends that have flown on British Airways 787-8 and indicated that they had to climb over the legs of passengers when the aisle passengers are in the lie flat position.

The question I have is whether you have to cross over the legs of these aisle passengers in you are in a business class window seat when the aisle passengers are in lie flat bed position?
