There's no "complimentary" snacks on Frontier. Which is fine, their flights are cheap and comfortable and the snacks are affordable. I also don't really appreciate having to pay for a carry on. I knew about this so made sure my bag would be considered a personal item, but I just don't know how I feel about that as a backpack may not even fit under that seat. But again, the flight was cheap. So, I don't know.

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.....

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

Its a scam! They act like they are giving you a break by having you buy cheap flights but in reality it costs more than a bit more expensive flight. I had to pay $45.00 each bag no matter if it was checked or carry-on. In total round trip I paid $180.00 extra just for my husbands carry-on as well as mine. Must add that our flights together cost 286.00. We should of went with American Airlines. On top of that we couldn't select our own seat if so, we had to pay extra, so we had to sit separated from each other. It was ridiculous! Never Again with this company!!!!!

The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

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.
