I had an e-ticket for a cancelled flight, was paged the night before (thanks to the UA flight paging feature on the website), called 1K reservations, waited on hold for a record 21 minutes, and rebooked for the first avail. flight, which unfortunately was 24 hours later. I never took the flight, opting instead to drive the 500 miles with a couple of other adventurous folks whom I met while waiting standby for an earlier flight. Had more fun and got there sooner than the re-booked flight...
