There were weather issues in the area apparently; however, that was not obvious from what we saw outside of LaGuardia. We were delayed leaving (which I understand); however, once we were on the plane we didn't leave for a long time. It may have been two hours?? - all I know is that we sat there for a long time with no information as to why we were not taking off. Finally, after 45 minutes to an hour (maybe?), the pilot gave us an update that no planes were able to go in the our flight path direction (or something like that) due to weather. There was nothing additional added. What does this mean? Why is this? What are the options? When will you give us another update? There were no updates for maybe another 30-45 minutes. There was no explanation as to why we couldn't be rerouted to avoid the weather. We had no information at all. We just sat on the plane (for about 2 hours) with very limited information. All I would have wanted is an explanation as to what was going on. Tell me there is bad weather coming our way. Tell me they are working to reroute us around it (which is what they did). Tell me SOMETHING.

My 4pm flight did not leave until about 10pm. I did not enjoy this experience.

I had an extensive delay on my previous flight and we had another delay due to the crew not being there. We were scheduled to have a late arrival but due to the delay it was even longer.

Had one of the worst travel experiences I've ever had. 1.5-hour delay turned into being held on the tarmac and our pilots timing out. Was supposed to take off at 4pm and didn't take off until 10:30pm.

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

The flight was delayed at the very last minute and no information, both of my round trip flights were delayed at least the BNA to Boston was informed earlier but the return one was horrible

Nothing really it’s just the flight availability that hurts sometimes

Delayed, then set on termac before taking off for 45 minutes. After landing had to sit on termac for another 30-40 minutes. Total disaster of a flight

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

My flight from Honolulu (UA 1221) was on a very old 757, no video monitors anywhere. If you wanted to watch a movie, you needed to do so using the United app on one’s phone. WiFi was $8 for Mileage Plus members; I demurred, choosing to spend my time reading a novel using the Kindle app on my Samsung S26. The meal was okay … Breakfast on any domestic airline is so-so as a rule and this one was no exception. The best part of the meal was the fruit plate and the warm croissant. The highlight: The flight left on time and arrived early.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late

The plane left over an hour late. I missed my connection going to Tokyo. They haven’t sent my bag to Thailand, where I ended up. It took me over 32 hours to get here. Very bad experience so far. I hope they can fix this and get my bag to me, within 24 hours it doesn’t look good at this time.

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

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Tired of being nickel and dimed for every little thing, especially carry-on luggage.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.

Late start, late arrival and very uncomfortable seats. No legroom, no elbow room because the person next to me was fat. I had to press myself toward the aisle or be rubbing arms with them. As a result, I was bumped every time someone passed in the aisle. But I couldn't get away from the hip encroachment. Who wants to rub hips with an oversized stranger for over 2 hours? I'm not fat, just tall and larger-than-average frame so I need to leg room but it would be nice if other peoples' body parts weren't squeezing under and over the arm of the seating. Why should it cost me so much for simple comfort so United can get a little more profit?
