Mediocre 2.0

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.

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

I really like how your flights are inexpensive compared to others when trying to purchase a last minute ticket.

The last two times I traveled ( I flew with United Airlines ) and both times my flights were delayed. The first time it was delayed by 4 hours and made me miss an appointment. The second time it was delayed by over 13 hours. It was nice that United had put me in a hotel room for the night, but again it took away from time in which I needed to be somewhere else.

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.
