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.

Jet Blue didn’t transfer my baggage to the company which I would fly with after, and if the office didn’t call me I would have my luggage lost. Not to mention that I had to stay caring it around the airport for 13 hours, until the time of my next flight.

There was a huge glitch in your ticketing, resulting in me confirming the same ticket 3 times. After calling Jetblue for customer service per your advice, they first suggested to give Jetblue credits for extra tickets. When I insisted that the issue was solely caused by kayak-jetblue ticketing connection issues, they supervisor approved to cancel 2 credit card payments... BUT I have to wait for 2 weeks to see the cancellation on my credit card. Unfair and ridiculous, if you as me.

There was only one individual checking people boarding. Two individuals at the boarding gate would have been even more efficient.

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 call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

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.

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!!!!!

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.
