Airline reviews

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

l really enjoy very much the flight was very pleasant

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Airline staff was good the checkin process was ok but the plane itself was very bad the comfort was worst it was worst and the most stiff 5 hours of my life i felt claustrophobic

Brutal as can be … delayed by 24 hours then delayed and hour on the tarmac then delayed three hours in Chicago, screaming child behind me kicking the seat for the better part of 10 hours… couldn’t be worse

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

Economy seats always cramped, no meal on international flight, no plugs for electronics, but we got there and cabin crew was excellent.

Pros: The airplane was new and had in-flight entertainment (tablet behind seats) with new movies instead of watching on personal devices. Cons: the flight time was changed without informing us. When I booked the flight, the time was 13:30pm (also in the email confirmation). However, when I reached the airport, the time was conveniently changed to 14:55pm. When I asked at the counter, they said the flight always took off at this time. The booking was made by Air Canada, but the flight was operated by United.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

Flight was delayed by 45 min. No problems. Everyone took it in stride.

The Flight Attendant was particularly helpful to my wife, who was having a bad day.

We had no idea that you had to check in with United so we were waiting at a closed Air Canada window for about an hour before we found out we had to us United.

Boarding staff provided up-to-date flight information. They were professional and courteous. The flight was on-time and comfortable (adequate leg room). Early landing and orderly exited the aircraft. Ground baggage handlers were quick to offload carry-on bags. GREAT EXPERIENCE WITH HK EXPRESS

The flight was on time, boarding was smooth. The crew was did an excellent job traffic controlling as people boarded.
