had to take another flight, ticket agent was able to change me to a different flight on JAL. however, JAL could not access the ticket info and ticket agent would not take my payment. result was missing that flight, ticket manager told me it's my fault and tough luck no refund. American airlines told me the same, ended up losing my money for the ticket purchase. i booked another new flight with another airline direct. worst experience in my life using kayak.

The crew was helpful and friendly, my flight was inexpensive

The seats were incredibly uncomfortable! Also, many people did not understand how to turn off the televisions, so it was pretty distracting to have so many monitors going when we all trying to sleep.

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.

No hassle of changing terminals in JFK, no bagagge claim, AA check-in-this time, was a "good luck"....Connection in Helsinki, very quik!

Finnair flight AY06 are old aircrafts. Every other in-seat monitor was out of order, flight attendants could not do much. That created mess for passengers, trying to move their seats to the ones with working monitors.....

Almost everything. Only the food was lacking. I like their new planes. The outlet at the seat in coach. The magazine options at the seat as well. I did not look at the entertainment so I will not rate that. The crew was professional.

Just the food options. Ginger snaps was what was served for food and a beverage. I suppose this is what obtains on most airlines these days but can't I hope for something more like maybe a sandwich? AA has the opportunity to set themselves apart in this area.

I booked a LATAM flight for a 10.5 hour flight specifically because they have better in flight entertainment. I arrived at the airport and found it it was operated by AA. 10.5 hours with zero in flight entertainment. HORRIBLE EXPERIENCE.

I liked the expediency of being rescheduled for another flight and the kindness of the American Airlines staff. When I first received my boarding pass, the pass listed gate A24 as the one where my flight was scheduled to depart. The plane destined to depart from Dallas to LAX did not show up. However, a few of us were kindly offered a cot and blankets to sleep on. The next morning I folded the cot and the blankets and found an American Airline staff member who swiftly rescheduled me for another flight to LAX. She did state that the original flight had departed at 11:15 p.m.

From around 6 P.M., December 11, 2017, I was at gate A24 - the gate listed as the Departure gate for my return flight to Los Angeles. The last flight that left went to Saint Louis, I believe. There was never a flight to depart from Gate 24 to Los Angeles. I believe the gate may have been changed and for some reason, those who were at Gate 24 were not informed. Also, the travel instructions on the advertisement for scheduling the flight mentioned the ability to carry on luggage for no additional charge. When I received my boarding pass, it stated I was only allowed to carry on baggage that would fit underneath the seat and not in the overhead bin. I had to pay to check my baggage that I thought was free. In spite of the changes, the flight was a good flight. Thank you

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.
