It was as good as it could be. Flying is not a pleasant experience these days.

Very good flight. Crew was great. No issues and we even arrived early.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Flight and seats were great. Food service was average at best. The real main problem we had is that we got cheeseburgers for the kids but the plates was extremely hot. Like ridiculously hot and the stewardess never said anything. Luckily or unluckily my wife touched the plate and was able to deal with it before the kids got burned.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Entertainment kept turning itself off. Gave up on watching a movie.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Not United Airlines' fault. It's ORL airport's fault.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Very poor the plane itself was really old, slight smell that couldn’t be named. I didn’t even get a boarding pass UNTIL AFTER clearing security! Even then, they said when I get to my connected flight I’ll get my 2nd boarding pass there! A bit ridiculous!

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

the head jack on my seat didn't work and the power outlet didn't work for my seat

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Was a normal flight but it was delayed, and there wasn't an explanation.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Flights were on time. That's the main consideration since I had to change planes. The entertainment was whatever you bring with you and the food (in Economy) is non-existant. Neither of those was a surprise.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

The gate crew did try to help, however they lacked the information as to whether the flight will operate or not. Being delayed 6 hours and in a limbo on whether the flight will operate or not is not fun. The airline having staffing issues is not encouraging at all.

Flight was delayed and missed connecting flight. Did not give warning about delay until we showed up at the airport. Not good.

I love to be able to connect my own devices to the entertainment system. It works great!

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

Fair. What's the point of partnering with United if we cannot use the lounge. My wife is a frequent flier with United but we were refused access to Air Canada lounge

The mid flight snack could have been more substantial than tiny bag of pretzels.

We left a CPAP machine under the seat and informed them. They emailed after 3 days delivery or ship! We paid $54 and stayed at the house every day for 10 Am delivery “Priority overnight” . It was never delivered. Emailed and Martin kept replying that label was created. I had to leave on Sunday so we went to lax in person and after 2 hours asking and going from one place to another, we finally got it. Very disappointing experience. Air Canada DOESNOT have a customer care line to call to speak to a live person. Cpap machine is a breathing machine for sleep. I had very hard time for a week. We could not get out and explore California every day as we were expecting FedEx 10 Am delivery ! It’s crazy that they charged us too and now they don’t even refund. No more air Canada!!!!!

Clean plane, nice crew, on time flight all good. No real issues, a pleasant flight

Once the flight was boarded, the captain let us know there was a mechanical issue. Multiple other updates followed (mechanical issue is within acceptable parameters, just kidding it's not, we might have to get off, just kidding, we'll stay on but now we need the log book. Ok now we have the log book, now we're gonna leave. Just kidding NOW we're gonna leave). So I arrived at 11 am for my 2pm flight, but the flight didn't leave until 4pm. Why the bleep you want us to get there 3 hours ahead when there's gonna be two hours more to wait? That's five hours of my life I'll never get back... my time is worth something no? And the time of all those other people... how many people on board maybe a few hundred say 300 times 5 hours wasted. That's 1500 hours of people's lives dude. Come on.

Staff was great at checkin as well as flight crew. I also appreciate the effort to keep carryon at the intended limit
