I was flying SEA to AMS last week Comfort+ and the security line was HUGE! I thought I would chance my luck and flashed my boarding pass with SKY printed as the boarding zone and with a breezy, 'is this the right line for Sky Priority?' was waived through.

It was very cheeky and I hung my head in shame as I passed the snaking queue and was through in 5 minutes!

I used the time saved to have a few extra drinks to make me forget my shame!
