The destination, the time and direct flight.

When I got to check in at the airport I found out I had to pay $100 per bag. This was never told to me when booking. I was also made aware that if I had booked my bag when I checked in on line each bag would have been 75$ . Of course I hadn't checked in on line and this was a huge surprise.

The economy seats are more comfortable than average transatlantic flights on other airlines, albeit far from perfect. The meal was nicer too. The crew both onboard and on land was nice and attentive.

The entertainment system is slow and the selection of films to watch could be better.

I paid for priority boarding but never had the chance to board early.

The flight crew from the mel to lax route were excellent. One was especially attentive to my 2 toddlers and gave me a bit of a break, something that has NEVER happened in over 40 flights traveling with children.

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.

The computer system really needs a lot of improvement. We were checking in with our infant daughter and it took 50 minutes to check in with a senior person helping the check in person and phone calls to their technical assistance. We were told an infant is difficult in their system, and our dual national daughter was another layer of complication.

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.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
