We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced.

Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid...

Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade.

Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip

I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

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,
