United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

Flight was on time. Boarding was smooth. Flight attendants were friendly and efficient. Entertainment system was broken for all passengers on the left side of the aisle. I would prefer if meals were not served on red eye flights. No one should need to dine at that time and it is disturbing for those passengers trying to sleep.

Gate agent did not hold flight for connection, provided no assistance to get new flight

I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

My return flight experience was one of the worst times I have had traveling anywhere this year. Not because of the flight. It was because there was not enough time allocated to deplane, go through U.S. Customs and U.S. Security to get to the gate for the connecting flight to Boston which I missed, There was well less than an hour between my landing in Montreal from Prince Edward Island to my connecting gate. I even called Air Canada on the morning of my return and noted my concern over the short layover time, not more that 45 minutes. The initial flight was four minutes late. I was seated in the rear of the first aircraft, and it took at least 20 minutes to deplane. The U.S. Customs was a considerable distance from the gate at which we landed. The need for double security seemed unnecessary and redundant. The distance from the security to my gate was again fairly great, and the wrong gate number was listed on my boarding pass. The agent I approached at the flight that was going to Newark, New Jersey was too busy to answer my question as to what gate was for Boston. When I got to the right gate, they had just closed the door to the aircraft even though I arrived a minute late. If I knew the distance to Customs and from Security to the gate, I would have asked for a seat on the next available flight which was 4:30 pm. When I made my call at 6:00AM that morning. When I asked the agent at the Boston gate, he said that the 4:30 flight was already “OVERBOOKED!” I was put on an 8:30 PM flight and didn’t get home until MIDNIGHT. I then had to care for a barnful of hungry animals and didn’t get to bed until 2:00 AM.

From Montreal to Cincinnati the flight was perfect! Flight free and everyone was perfect and a pleasure to travel with. But from Casablanca to Montreal the flight crew were quite cold, unhelpful, also seemed to scold many passengers instead of simply educating or instructing them. There were a couple for sure I could describe but not name… i was really shocked bc my experience w air Canada is typically a good one at the very least. It seemed something was very much so I’m the air w the crew. The two older lady crew members and the male were amazing but the younger lady crew members w the exception of one were very clique-y and snarky, sassy

Seating wasn’t too cramped; I don’t understand how luggage bins get full if there are enough for each person. Shouldn’t there be room for the designated carry-on and personal item for each passenger at their seat? THEN, IF for some reason extra room is available for someone who prefers it, then shifts can occur. I’m simply saying it seems that I should have primary access to the storage bin at my seat and underneath in front of me. It was suggested that I go to the back of the plane to store my carry-on when I paid to have access to the first seat after 1st class. The additional stress and inconvenience could be avoided and I think all passengers and flight crew are interested in guidelines that are fair, clear, and reduce tension.

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.
