Airline reviews

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Food was terrible Not many options Stewards dont care Delay

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

Cabin crew were great. Seats are criminal for tall people

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped
