Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

The food was the worst I’ve had on any flight I’ve ever been on.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Breakfast was not loaded at SFO due to catering company change. Seems like a major airline at a major hub would have thought of something else or warned passengers to pick up food before boarding a 3 hour flight.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.

Bad experience boarding and flight got delayed didn’t make it to my next flight

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Before final boarding, my husband and I — both seniors — were told that we could not bring our carry-on bags with us due to being in Zone 6. The staff took our bags with little explanation, stating it was policy. While we understand boarding procedures may vary by zone, the way we were spoken to was unnecessarily rude and dismissive. We felt disrespected and singled out, and the interaction left us deeply uncomfortable. As seniors, we expect to be treated with courtesy and dignity, especially during travel when accommodations and communication matter most. We hope you will look into this matter and ensure better training for staff in handling such situations with more empathy and professionalism.

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

No Charging ports for personal electronics, which were required to use wifi entertainment.

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone
