Daughter in law works for QF/BNE. She said he refused a wheelchair belonging to QF/JQ after his own went into the hold, due to being far to large for isle, and much to the horror of staff took off on his own to the John. Its called publicity, and as much as I admire the bloke, its a bit rich to blame JQ or any other airline for that matter, if you decide to go around a airport on all fours.
