On Saturday, my first time using Gatwick, Fast Track was open and I didn't need a sticker to use it. There were 3 people ahead of me at the x-ray machine. The lounge was good and, better yet, it was almost empty.

I was foolish enough to leave the lounge when the departure board showed "Boarding" even though actual boarding didn't commence until about 15 minutes after I arrived at the gate.

The flight was LH and, although they announced priority boarding for First/Club/Gold/Silver, there was no one in place to enforce it.
