Was scheduled for 12/25 MDT-PIT-IND #977 720p - 815p / #341 845p - 1002p. The PIT - IND flight was cancelled due to crew calling in sick (US had around 100 flights throughout the system cancelled because of crew calling in sick). Ended up at PIT airport Hampton Inn and Denny's for dinner. Got on 12/26/01 PIT - IND US Airways Express flight instead.
