On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

We had the best flight attendant ever! Her name was Sharon on Eandeavor / Delta Cnx, and she made the experience the best flight I've experienced. Thanks Sharon for being awesome!

The flight staff was rude, the wrong gas was put in the plane causing a delay, I missed my connection because of this where they wrote it was delayed because "it was snowing in Savannah" which was a blatant lie, but made it so they did not have to help me in any way since their delay was "weather" related. They could not get my to my destination until noon the next day which forced me to buy a new flight on Alaska air. My flight on Alaska was absolutely fantastic and I regret ever buying any United flight and will not in the future.

I ordered a special meal and it was delicious! Because I have dietary concerns, I often have to order a special meal. Usually, I find that the alternatives meals are second thoughts and thus can be rather tasteless. I was very thankful for my meal.

The plane was so tiny we were packed in it like sardines. I am a rather small person (barely 5 feet tall) and usually have no complaints about space on a flight but even my knees hit the back of the seat in front of me.

There was a change in our flight. According to Delta you didn't confirm every leg of our flight and the plane was over booked.

The crew was late so we were delayed two hours. I find that extremely infuriating when you are a passenger and have to show up two hours before your flight. I also would lose my job if I was two hours late for a client.

no greeting from the captain and no other update from the crew during the flight. The plane was new, and had a utilitarian feel, not luxurious for sure( but not bad)

We did not crash. Eventually we got to our destination.

All flights were awful. None were on time. I paid for economy plus aisle seat but was put in economy middle seat anyway. Asked for refund and was sent to 3 different people. The final person, a gate agent for my departing gate, Peggy Hunter, told me that she has 35 years experience and she knows everything about United Airlines’ processes. Told me the only way I might get a refund is to submit online but that paying extra for a seat upgrade doesn’t mean I will actually get one and that I should read the fine print on the ticket. Had previously spoken to another gate agent who had told me that I could ask for a refund at the departing gate. Wifi didn’t work. On one of three delayed flights had to beg for water to take my medicine. I will make extra efforts to avoid using this mediocre airline.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
