I don't understand how the upgrade works. last time I got cleared at the gate, with only two people requested upgrade, I was #1 (as a gold member!)
I was not cleared at 24 hours. when I checked in online it did ask whether I want to stay on airport wait list. there were 5 empty first class seats when we took off. totally no idea why they didn't clear me at T-24.
I'm not complaining though as they didn't deduct my stickers!
