Awesome and helpful crew

Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location. Food was not good, and drink service was only done twice on 17 hour flight. It took an hour to start taxiing after we were all seated and left the gate.

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.

Flight was on time. The united employees were really nice.

I recently had knee surgery. So, I booked isle seats for my trip. However, I was placed in window seat on regional jets. It was pretty uncomfortable.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

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.
