Agreed! We had a United flight canceled from Scotland to Chicago due to mechanical issues. They had to fly the part over from America in order to fix the plane, so we were stranded for two days. Fine, these thing happen. They told us they would reimburse hotels, but we had to find our own…it was the beginning of the Tattoo in Edinburgh. That was the first nightmare. They then told us we would all be rescheduled in our same seats on the same plane, but we’d need to call to get the new gate number and departure time the next day. I called the next day, and I was on the original plane, leaving at 8am, and my two minor children were on a different plane leaving on a 6:30 pm flight. It took me HOURS on the phone to get this corrected, then trying to get reimbursed for the hotel and taxis was another level of purgatory. Not to mention they lost our luggage on the flight there even though our flight was delayed by six hours - not quite sure how our luggage didn’t make it from check-in to the plane in six hours. We haven’t flown United since.
