The only time that I was lucky enough to fly in a triple 7, I was flying back home from BPT-IAH-LAX on CO. When I checked in at BPT, they put me on the upgrade list. After a delayed flight, I barely made it to the gate in IAH and the gate agents were waiting for me with my upgrade. I gave them the upgrade cert from my Prestige Pack and proceeded to board for a very pleasant flight back to LAX in BF. I am 6'3" tall and could not believe the room that I had. I had to unbuckle my seat belt just to be able to reach my laptop under the seat in front of me!
