Well, ETC is now back up, but web check-in didn't work for me:Invalid Passenger Name Record (PNR)
Possible reasons/solutions:
* The PNR has not been e-ticketed. You can only use Web Check-In with a valid e-ticket. Please check in at the US Airways ticket counter at the airport.
* The PNR and e-ticket are out of sync. Please check in at the US Airways ticket counter at the airport.
The PNR locator was correct and the PNR had a ticket number. Oh, well.
UPDATE: Third time is a charm!! After tryting twice, getting above result, and kvetching on the board.......it worked...pretty neat. I could even see how many other standbys were checked i.
