E-upgrades - what am I doing wrong?
Last year, I had no problem using the last of my e-upgrades in January-February, but this year I am ending the year without 22 points (I know, I know, others have a lot more) because I just can't seem to score an upgrade. Maybe I'm doing something wrong. Can someone tell me:
1. If I request an upgrade within the Elite 50K window, does that request remain on my account? Why do they ask me again at check-in whether I want to e-upgrade?
2. Does the time of check-in affect one's place in the queue?
3. If I request an upgrade 5 days out and a SuperElite traveler requests one an hour before the flight, does he or she still get priority over me?
4. If I haven't been upgraded by time of boarding, is it best to wait around to see if someone gets called or just get on my economy seat?
