Good 6.0

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.....

Okay 5.0

Good leg room

5 plus hour flight and one movie as entertainment option shown on a tiny screen from cabin headliner. Like in the 1980’s. and do not forget your headphones or you will be buying some earbuds!

Good 7.3

Oh the crew was very pretty. They spent more time on themselves their hair their make up and on their phones than they did the entire first class. Check our flights and miles. We fly AA ALOT for ourselves and other. WCB4350 Shipman. We don’t complain ever. But when you spend what we do and only just get your first drink with your dinner in the air is utterly ridiculous. Never got a clean up or a second drink. Had to interrupt the glam squad from their phones and make up bringing them our dirty glasses and trash asking for a second drink. Not impressed with this crew at all! Normally AA IS TOP KNOTCH. So it sets the standard that we’ve been accustomed to however complete and total letdown on this flight

Mediocre 2.0

nothing

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.

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.
