The temperature on the flight was unbearably hot and they were unable to serve waters and did t make any adjustments. This impacted us both when leaving, we pushed away from the gate but didn’t taxi for takeoff for awhile then arrived ‘early’ yet were stuck in the plane for longer than we should have been.

Terrible - the flight was delayed taking off after boarding. Then the flight circled lga before landing. Significant delay

The actual flight was smooth and we arrived earlier than expected which was great. The flight attendants gave unclear instructions and were rude. They seemed overwhelmed or flustered for the flight. Inflight service was delayed and unsure why.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

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.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

My return flight to Honolulu (UA 1170) was on a 777-200. I’d forgotten the weird seating arrangement in first-class (2-2-2); I was in 1B, so I faced the passenger in 1C. Unfortunately, there was a problem with the flight computer, so we left LA an hour late (6:05pm). The meal I chose was Korean BBQ Glazed short rib. It was served with a nice salad and fried rice. This meal was better than breakfast on the outgoing leg. All in all, a decent flying experience. Ratings: 777: 3.75, food: 3.5, service: 5 (out of 5).

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

I did bought anything… I don’t understand how this book appears to me . Ridiculous

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#$%".

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.

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.
