Well in Manage My Booking not a single aisle seat appears on the selection screen thus in the middle row of the 777/300 only two seats appear and on both windows sides only window and middle seat appear, this for all flights. To BRU is an A359. It also was not possible to navigate to Manage My Booking from the main Booking screen, entering name and PNR on My Trip just brought me back to the Booking screen.
