Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

Really delayed, no effort to support customers other than “sometimes we run late.”

It was serviceable, nothing special but nothing awful on this leg.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

My wallet fell out of my pocket ( my fault). Staff claimed they looked while cleaning. Said they didn't find it, but was actually found in Washington DC on the plane. Which mean either they didn't look or don't do a good job of cleaning. Now I have to pay 27 dollars to get it shipped back and have no wallet for my entire vacation

My flight attendant was miserable. Bathroom filthy and the water soapy in the tea. I’d choose delta everytime.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

DCA-LAX No screen on a 5 hour flight (almost) no food for sale on a 5 hour flight (practically) no wifi coverage or speed on a 5 hour flight I should have gotten my money back, shame on American

Flight was good, little delayed because of busy plane traffic

I had ridiculously long body search because I have knee and hip replacements

My luggage is missing. I haven’t received it. No one seems to know how I can find it

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

Flight was on time. Boarding was smooth and orderly. Flight attendants were friendly and professional. Bags came out soon after arrival.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

90 min delay for a food cart that needed to be fixed.
