I have an award ticket booked via AS that was previously showing ticketed, and now is showing "On Hold" with the hold date being 24 hours before the flight.

Several other people over at the AS forums pointed out that several AA issued tickets had the same issue and also quoted a technical glitch on the website. At least one person over there confirmed they were able to check in with no issue.

Comforting to know it's not just me Hopefully everything works out for everyone.
