The only way to get through international travel anywhere is to lower your expectations. You just flew miraculously ~10 hours across an ocean during the biggest travel season of the year, on Christmas Eve, and your complaining that you have to spend a few extra hours in customs?

No offense but count your blessings, 70 years ago this trip would’ve taken you weeks, and 20 years ago you wouldn’t have had the whole world at your fingertips to pass the time while you wait.
