If AC is clearing wait listed eUpgrade requests at T-36, and you can no longer request an eUpgrade after T-24, am I correct that there’s a 12 hour window in which you must request an eUpgrade to a flight for which you’ve already requested one if you want a hope of getting upgraded at the gate?
This seems like an absurd redundancy compared to, say, leaving people on the wait list or going back to same-day upgrades.
