Extremely commercial in the name of budget airlines! The flight wasn't cheap or anything! But money speaks everywhere and ALL the time with this airlines. $2 for a can of soda. Carry on bags- pay! For whatever reason you decide to buy it at the airport- extra! Seats- very uncomfortable and you couldn't get better even if you paid because the whole flight has the same kind! Use this airlines at your own discomfort!

I would like if for my return from Paris to Chicago, Chicago Seattle I would be greeted by the personal and offered to flight first class without extra charge to compensate for the bad experience on my way going in. Thank you

I was told I would be able to choose the seats only 24 hours before the flight by going online. I tried to choose the seats online but could not have access to the site. I then called the number provided to ask for more help, and was told that I could then only choose the seats at the check in time. I was at the airport 2 hours before the flight schedule to book my seat and was told them that I could only choose the seats at the gate. Once I got at the gate I asked the person to please give me a seat at the aisle for medical reasons but after waiting until the boarding process had started I was giving a middle seat. Not only I was treated as a stand by passenger that had not purchased the tickets I was put nt on group 8 and at the moment of boarding the gate personal aggressively grabbed my carry-on bag because they insisted there was no more spaces in the compartment above heads. Once I got inside of airplane I saw many empty compartments available for carry-on luggage. I wish I had not purchased my ticket with Iberia Airlines operated by American Airlines. It was not a good, pleasant experience and do not recommend. I wil certainly avoid in the future and not travel this way another time. Thanks

Lights turned off at night, not a lot of announcements to disturb sleeping passengers. Plane was clean. Crew seemed fine enough.

To begin with, a three-hour delay on what was already just a four-hour flight, and no steps made to even offer snacks or discounts or other amenities to apologize for the gross delay. Very uncomfortable seats; even dead tired, I could not get much sleep. I usually use the food tray as a place to rest my head, but it was far too small to use for that. Upon landing, another 45 minutes of delay as we waited for our gate to become free, and again, no measures taken to apologize or make us as customers feel like they wanted us to feel even a little bit better about the situation. I get that it's a cheap flight option, but even so, the company needs to take more responsibility for its internal problems.

Well, this flight was a disaster. It already was a redeye as we were going to get into Chicago at 5:00am. But then our flight got delayed 3 hours in Seattle due to "technical difficulties" and we didn't touch down in Chicago until 7:45....then you know what happens? The flight doesn't have a gate because we were so late, and thus we had to wait in the plane for another 45 minutes. It was at this point frontier emailed me a voucher, which I was fine with....but then getting my luggage (which you have to pay extra for to be checked in) was shredded entirely on its side, as if they had dragged it on its side. Nice service.

I'm not sure how it's legal that spirit doesn't include the exit tax for a country when every single other airline does include it in their KAYAK posted price. There is literally a tax window in San Pedro Sulu, Honduras that says for "spirit airlines passengers" charging $47 per person that my family of 5 had to pay to get out of honduras. Continental would have been cheaper. The exit tax for a country is a required tax. Why is the tax included in the KAYAK posted continental price but not spirit? Only spirit airlines passengers had to pay it. That's messed up. Kayak should be more aware that prices they list aren't truly accurate as all the required taxes were not included. I'm not talking about baggage fees or meal fees or seat selection fees which aren't required if you don't want to pay it, I'm talking about a required tax to get back on the plane.

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.
