Happy and helpful crew even though there were many upset and stressed out travelers.

Extremely long lines at check-in at SeaTac, over 1 hour spent in line just to drop off a bag. My flight plus the two before me were delayed.

The airline staff are great about boarding and exiting swiftly, which makes it convenient, especially for any delays.

The lack there of options for flights to my destination makes it difficult, especially when the layover then becomes an entire day of just waiting.

The crew made the best out fo the terrible situation.

Right after we boarded the plane our flight was delayed because of thunder. Instead of keeping us from boarding until our flight was clear to go. We stayed on the airplane at the gate for over 3 hours. In those 3 hours we were served pretzels and one cup of water. When the legal time limit had been reached and they were about make us exit the plane they decided we could take off.

In less than 24 hours I cancelled my reservation but they don't refund unless you cancel 7 days in advance, but I bought the ticket less than two days before my travel date and then cancelled the next day in the 24 hour grace period. They said I could get a credit to use in the next 3 months,but I will not be needing a ticket in The next three months. My travels are over. I am really pissed off. I will NEVER FLY FRONTIER again.

The crew was friendly.

Far and away the most uncomfortable and worst value-for-money international flight I've experienced. This plane is so old it should be put in a museum. The warm food was terrible and the non-hot food was completely frozen so even if I wanted to eat it, this wouldn't be possible. Individual seat in-flight entertainment screens have been the norm for many years, yet this plane had the community-style in-flight entertainment. Half of the time, the screens weren't working, which just made matters worse. The total lack of legroom and chair ergonomics made getting comfortable nearly impossible. I was literally in pain sitting in these seats. I live in Prague and visit family in the US often. This was my first experience with American Airlines' newer direct flight option from Prague to Philadelphia; based on the extreme discomfort of the inflight features and to top it off it was the highest price I've paid for a flight back home...(total lack of value for the money! )I would go out of my way to make sure I never take this route 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.
