We were scheduled on AA71 FRA-DFW in Business class on Sat. After 3 hours of rolling 30 min delays, the flight was canceled. Took about an hour to get our checked luggage and another 45-60 min in line to get rebooked. Since UA canceled two flights out of FRA on the same day, rebooking was a problem for many. I called AA and asked for the LH non-stop FRA-SEA the next day (that alone made the $90 for experflyer well worth the cost).

I think some of the economy class passengers were in line for almost 3 hours and there was precious little left for them when their time came for rebooking.
