Can I change to the 7pm flight at 7 am or 5 am? (for 25 dollar fee, of course)
Am I included on the upgrade standby list as soon as the change is confirmed or do I have to go to the airport/gate to be put on the upgrade list?
You can change to the 7pm flight at 7am (within 12 hours of the new departure time AND within 24 hours of scheduled flight); at 5am you'd be 14 hours from the new departure time.
I have no idea when you'll be put on the upgrade list, but that will only be the third tie-break after status and fare class, so I wouldn't sweat that too much. As long as you're on the list at T-30 or so when they start clearing upgrades at the gate you'll be fine.
