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#$%".

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.

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.

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 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 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.

It was my first time flying with Alaska Airlines and it was a pleasure!

DFW notification of changing the gate notice was an inconvenience.

Our gate was changed several times, and the gate agents were just as in the dark as all of us in knowing when our plane would arrive at PHL.

Very long delay at PHL. The old section of terminal F is a disgrace. Take-off was 3.5 hrs late. It was not just the bad weather, but also too many jets occupying too few slots, a very PHL-based problem.,

Aa cancelled my flight where I was in first class seat 4B. They auto rebooked me on another flight, did not give me a seat assignment until at the gate. Where I got seat 29f, for a 4 hr flight. No accommodation at all for my first class ticket. Left 3 hrs late as well.

It was delayed 5 hours due weather and your app should be rebuilt or disabled. I could not change my original flight on delta so I did it through the delta app. Then rebooked on American once delta cancelled all flights from LGA to PIT on 8/27. American Airlines was fine once the flight took off 5 hours later. I wish my company would find a better provider than kayak.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

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