*Just to clarify, on day of departure your upgrade will be handled no differently than if you had bought a US ticket. You are still in the queue with the CPs in order of check-in.
Just a note that you can use On-Line Check-In at usair.com up to 24 hours prior to departure time.
You don't have to wait until 23:59 if your flight is at 10:00 am the next day for example. You can check-in online starting at 10:01 am the day before.
