On the MSP to ATL leg the gate crew made a huge deal about checking rolling bags. They even stopped us at check-in and nearly begged us to check our bags pointing to the backed up jetway. But we had a lot of unpacking to do before checking our bags so we politely declined three times. On getting to our seats there were at least 8 open slots for bags near us. I heard a crew member call forward to say "tell them no more rollaboards" so they forced everyone left to check. On departure they slammed shut several very large empty overheads. WTF

Flight was on time and I received my checked baggage.

Seat was uncomfortable due to insufficient foot space. All (about 6) overhead bins in the rear of the aircraft were full because crew stored “essential equipment” in them. Crew was not professional. After takeoff they never came around to see if anyone needed anything and not even a glass of water was offered for the entire flight. They didn’t even ensure that everyone wore seatbelts on landing - woman next to me was stretched out hugging her companion while landing wilth unbuckled seatbelt. Entertainment screen did not wirk properly.

I was delayed for over and hour and a half after arriving. I had to stop and eat in the airport. With chronic health issues addressed this way I will probably not use United again.

I guess San Francisco ATC (Air Traffic Control) decided the plane couldn’t leave San Fran until way past our take off time. Then it takes two plus hours to get the plane here unload and refuel and rest. So I missed my connecting flight to Redding. Which meant I had to fly to Sacramento. Then I had a pleasant 3 hour drive on I-5 (can you sense my sarcasm?!) didn’t reach my destination until 5 in the FREAKING morning. Around 8 HOURS LATE TO MY DESTINATION

I flew economy. We left the gate on time, the seat was comfortable, entertainment was varied, flight attendants that I came in contact with were professional and pleasant, food was hot and very good, pilots got me where I wanted to go, and that little container of ice cream - oh I love it! The plane was not completely full, which made the seating more comfortable than it would have been if the plane was full.

I was ushered into what became a very slow line to board. The employee at the end of my line had to deal with a few problems so I ended up boarding close to the end, behind those with higher group boarding numbers than I. Having a single line up to the two boarding employees, would avoid that, albeit make a longer line to begin with.

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,
