I like the seats in the plane.

When we were bording, we had 5 bags and one very small handbag. And then the bording the lady who works there told us that we couldn't have more then 5 bags, because we are five people. She count that small bag as one. In addition, I realized that because we have different race, she did let us go.

One of the flight attendants was very customer-friendly. I had asked for a meal and they had a long, in drink service so it took awhile for her to come back to me. She didn't forget and she gave it to me at a discount so I was very happy about that as well.

The dirt cheap, I can't believe an airline can operate at this low an airfare and still turn a profit-ticket prices

The hidden checked-baggage fees that were almost half the cost of the actual ticket for one bag. The non reclining seats. The lack of legroom. The feeling of cattle being herded into a slaughterhouse. The lack of friendliness with the RDU and MCO gate/ticket counter agents. The cost of having to pay $12 to ensure I sit beside my 5 year old son on the flight. Besides a free seat belt, having to pay for everything else under the sun. Surprised AC was free. Not even an in-flight magazine or barf bag. Which is exactly what I feel like doing after giving you my money......

We sat at the gate because United oversold the flight. They offered passengers a great comp and a woman gave up her seat. It took 30 minutes for United to get her off the manifest and the other passenger on it. What a joke

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

I dislike that once I got to the airport in Cleveland before boarding schools go to Orlando they charge me $45 for a suitcase that if I would have painted with my ticket it would have been $25 and that's what it told me I had to pay at the airport if I wasn't going to pay it with my ticket it was only $25 not $45 so they charge me $45 and then when I went to board the plane to go in they tried to charge me $45 for a backpack that fits under the seat and wasn't a carry on then they charge like $3 for a can of soda I don't think I'll ever recommend Frontier to anyone or I would never travel again with them that is ridiculous being a disabled person and being taken advantage of is unacceptable

Amazing flight to Dulles international Airport. The United representative came up and saw that I was traveling alone and upgraded me to first class. It was the first time I have ever flown first-class. I was excited I didn't sleep at all so I can take advantage of all the programming that was on TV. I'm so very appreciative of the flight because I could enjoy stretching my legs out and enjoying a comfortable seat. The very attentive crew allowed me opportunity to quench my thirst with countless glasses of water and to watch and keep up with my sports programming throughout the entire flight. Now it will be extremely hard to ever fly coach again. I have flown United the last couple of summers and I have been nothing but thrilled with their service and their staff. Moving forward United would be the only airline that I would care to fly. Thank you for everything and thank you for my safe travels!

Nothing at all. Everything was amazing. United is now my only option for air travel. Thank you for everything United. My business will be with you for the rest of my days.

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,
