My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Liked nothing. As per previous segment it was delay delay delay.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.
