I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

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.

The flight was very smooth and good. Boarding was fast, but the staff was just decently friendly.

Air Canada flight staff are in contact negotiations and they are less than happy and it show. The process of self checking baggage is less than desirable with lack of support staff to help

A sandwich and a drink would have been better thank a snack bar...

I liked the behaviour of the crew members.The flight was good.

1 hour late No hot drinks No restroom in the back of the plane

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

No food to provide, they forgot that, in some cases, people stay at the airport for hours without food. Now, to provide them with food, they have to ask them to pay, because some don't have money. That way, they can't eat.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Horrible flight cancelled had to buy another very expensive ticket
