I was given the chicken dinner when I asked for the beef one - did not realize until the flight attendant was far away so I couldn't switch. This was a 13 hr flight - attendants did not offer water during the flight. No video options in English, only 1 channel on the screen on my seat, movie played on screen in front for all passengers to watch.

Boarding goes quick, nice seats in economy comfort

No free food besides pretzels on an almost 8 hour flight. Any decent seat is an upchaege to economy plus. WiFi slow, only can access entertainment if you have app download on phone.

Can’t think of a thing on this flight.

Delay after delay. Took way too long for de-icing. The storage compartmemt door got stuck and I could not get my bag out. The flight attendant blamed the issue on my bag. She claimed it was too big. It was not. I have carried the bag on several flights with similar planes, the gate agent slowed it on the plane as many have, and I had no issue opening and closing other compartment as I tried a couple after maintenance retrieved my bag.

The flight was over 4 hours delayed, and I didn't receive a notification that it was delayed until an hour after the flight was supposed to take off, which would have been ideal given that I had to pay 5x surge pricing for my uber to get there by the original scheduled time. Once we were about to board the plane, we were told again that it was further delayed. The crew was cranky and tired as they had clearly been dealing with delay issues the whole day. There were no tv's on the flight and we were told there would be free wifi to stream to our phones, however the wifi was so slow that it couldn't even load a single picture from the internet. Oh, there were also no decent food options on the flight. I will avoid United at all costs in the future, as my flight down was also over 3 hours delayed.

The crew was very professional.

The WiFi was very intermittent and made the entertainment hard to watch.

Boarding was delayed because the aircraft was being serviced. None of the tray tables or screens were cleaned. They looked like people sneezed on them. Disgusting.

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.
