I wouldn't risk it. Immigration can be quite busy in the morning when the airport opens as a number of long haul flights arrive in the first 30 minutes. I've had times off QF21 where it's taken almost an hour to get out into the arrivals hall.Hi Guys
If I'm on QF21 landing at 6.20am , am i safe to book the 7.40am JQ Japan to Sapporo , can't believe JAL have stopped running this morning service and am forced on the death star, does the curse ever end!!!!
