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!

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.

1. Plane engine set fire while taking off... leaking fuel. 2. My bag fee was waived, but the next day after being grounded and put in a cheap hotel for the night, I was RECHARGED $100. 3. They knew my flight left at 9pm, still gave me ONLY 1 hotel voucher so I was kicked out of the hotel at 12pm with NOWHERE to go for NINE HOURS with 125lbs of luggage. 4. They provided a good voucher, but the cheap hotel they put me in didn't have a kitchen, USELESS. 5. The flight was LATE getting to London the next day and I missed my BRITISH Airway connecting flight to Thailand. Had to wait another 7 HOURS to get a flight out. 6. Terrible service, over priced and rude agents. The agent told me " I don't know who waived your fee yesterday, but I'm not." Cold, considering the plane I was on the day before was shooting fire about to explode. 7. I was rebooked no choice of seating or consideration.

The woman at the check in desk worked patiently with us until she found us an alternate route. We werare given food and hotel vouchers to get us through the night.

Our British Airways flight was downgraded to a smaller airplane and we were not informed of this until we were in an hour in to waiting in a very long line to check in at the airport. We were unable to check in online the night before but not told why, and then we were unable to check in at the electronic kiosk at the airport but also not told way. When we got into the very confused and long line at the check-in desk 2.5 hours before our scheduled departure, we waited for almost an hour before anybody told us what was going on. They then told us that the flight has been downgraded to a smaller airplane, and that the agents were individually looking into rerouting passengers as they came up to the desk. Yeah sure does that the flight would not leave until everything was resolved and that people who had purchased their flights earlier would have priority. We then waited another 1.5 hours before it was our turn to speak to an agent at the desk. She told us that we would definitely not be getting on the flight because we had not checked in in time, which we had been unable to do. She then worked on rerouting us and offered us what sounded like an excellent flight option direct to Amsterdam on KLM the following day, however when we went to KLM to check in for the flight they said it was overbooked and we could go standby but we would not be guaranteed seats. We went back to her again and she eventually booked us on a Delta flight through Salt Lake City leaving the following day. We are currently in Salt Lake awaiting our flight to Amsterdam. This gets us to Amsterdam 12 hours after planned, Shortening our vacation with friends and causing us to miss events that have been planned. We are very upset that there was no information provided to us earlier and that British Airways did not, as is customary, first seek volunteers to take later flights, before bumping people off due to a lack of seats on their available plane. Instead they gave priority to people that had paid more money to check in with priority. We booked our flights 3 1/2 months ahead of time and feel that we were grossly AND unnecessarily put out by the actions and lack of communication throughout the process with British Airways.

I think something was broken in our section (mel to lax) as it was uncomfortably hot and the flight crew tried to get it cooler but could not. I’ve never experienced a flight that was too hot, usually the opposite. It was stifling.

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.
