Like Chix, I am beta testing the auto flight info service and it works great. You can set it up to notify you of things like: flight status, upgrade notification, flight cancellation and a few others. You can tell it to call a phone number or a pager. The nice thing is it is automatic based on you MP #; you never have to remember to do anything.

Another word about viewtrip.com. I just found out about it as well. It updates almost instantaneously. I called in for an upgrade, got off the phone and called up the record locator and the changes are alreddy there. Also, there is a link on viewtrip to flightracker which is a very cool way to track flight status. Check it out.
