I have never been so hot on a plane. Even with the air blowing on me I was sweating! It was crazy hot!

Friendly, attentive staff. Good service. My toddler, husband and I boarded first because of our child, so we had plenty of time to get comfy on the plane. The flight attendants served sufficient drinks and snacks for the 1 hour flight.

Flight was delayed two hours so my toddler and I had significantly longer to wait, which is not too fun. However, I understand this is unavoidable sometimes.

I hadn’t been on a plane in almost 10 years. People were very helpful at the airports. The plane ride was comfortable. The crew was nice both ways. I would. The price was excellent!

Nothing, absolutely nothing.

The flight attendants were pretty much what I've come to expect on U.S. airlines--overweight, older, and sloppy in appearance. One of them looked like she had rolled out of bed ten minutes before arriving at the gate. It was the complete antithesis to the flight attendants on Hong Kong Airlines. Ah, for the good old days of air travel. Before the plane ever took off it was announced the the entertainment system on the seat back ahead of those in comfort seats was not working and wouldn't be for the duration of the flight. Having paid an additional $239 for the comfort seat in the hopes of making a 16-hour flight go by a bit faster, this was unconscionable. The food was far inferior to Hong Kong Airlines. In short, it was the trip from hell.

I left New Jersey during snow storm. Flights had been cancelled on the previous days but our flight was not. It did not leave on time, had to switch planes before we actually took off. My luggage was lost. I did not make my connecting flight. Had sty over in Panama. Got to my destination a day late without my carry on ( checked at the gate...lost). Still have not located my other 2 bags. Very stressful expirence. Will not fly united again. Staff at my lay over was poorly trained at handling the situation and my luggage issue is taking a very long time to correct.

Good Movie Selection, food was descent, no screaming children,

Layover in Frankfurt too long; Unable to sleep on flight, nearby windows were open creating too much light, seating a bit too close to relax.

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,
