Hi All, I thought I would ask this question here before starting the formal process with United regarding a cancelled flight out of London this weekend. First the background. My wife and I were in London for business and were scheduled to return to the States on Sunday. I was on 931 to SFO and she was on 959 to ORD. Saturday night while we were at the pub she asked what her layover was in ORD on the way back. So I logged into her reservation and get the “schedule change” part on reservation. I look at it and see that it now has her on a 10am flight to ORD. When I first looked at it I thought it was a 10am on Sunday, but after looking at it some more I realized that it was 10am on Monday. This is the first we learned of the cancellation. We had not received any other communication from United despite UA having our contact information in their systems. From what I heard the reason for the cancellation was that BAA forced UA to cancel X flights on Sunday due to the expected snow. (which did come) So net result is that my wife has to stay an extra day in London. So we had to arrange to extend the hotel for an extra night and obviously the other costs associated with an extra day required to be in London. With that in mind I intend on invoking EC Reg 261/2004. My question for the group is. Have you ever requested this from UA? How did the process go? And what did you have to submit to UA? From what I can tell, we are entitled (I hate that word, but…) to €600.00 because the flight was cancelled and not accommodated within 4 hours, and the cancellation came within 24 hours of departure. Second it appears that we should be able to get the cost of the hotel as well back. The only caveat that UA may be able to invoke is “if the cancellation of the flight is caused by extraordinary circumstances which could not have been avoided if all reasonable measures had been taken.” However, because UA operated other flights that day including both before and after the scheduled time of her flight, including flights to ORD and EWR, and we were not offered other flights the cancellation could have been avoided, at least in my opinion. All of the other flights did not go out full, so there were other options UA could have used. I welcome your comments and experiences on this matter.
