Little leg room. I am 5'9" and could barely clear the seat in front of me. Trays were so small they were of no use. Seats did not have the ability to recline. You could pay extra for more leg room and a reclining seat but really? Baggage fees even varied as one cost one direction and $10 more coming back.

I checked in in advance of arriving at the airport, and the United personnel still made me use the kiosk, and the sit in a line for 40 minutes to drop my bag! Horrific Service!

I didn't like that Frontier has extra fees on top of the posted ticket price. It had extra fees for baggage and the prices changed whether you did check in online or at the gate, and then an extra seat fee and drink fees, etc. As it turns out, I could have gone another airline cheaper with no extra fees. I will not book with them again.

The crew was awesome and the pilot was honest about how delayed we would be.

AA was not upfront or clear on delays at all. The plane was very delayed and they did not communicate clearly.

The flight itself was fine

I bought the tickets together, but was informed at the ticket counter that i had only purchased tickets—not boarding passes. Boarding passes needed to be purchased by paying extra if my husband and I wanted to sit next to each other. I tried calling the customer service line through kayak and waited on hold for a long time with no indication of wait time. When the gate agent arrived, we asked and were moved to seats next to each other right away. The ticket agent at initial check in was very abrasive and non-solution oriented. if what she was saying was true— that we only paid for tickets and had to pay extra for boarding passes together— that was never made clear during the booking process. It’s unlikely I’ll use kayak again unless I know for sure what I’m buying.

Prior to getting in to the security area at RDU, my Mother in Law gets a pat down because she didn't have ID. (She hasn't driven in over 10 years). She kept her cool and cooperated.

I know the TSA was just following their protocol to help make us all safer, however, one look at her would tell you she was o.k. to go thru.

We could not check in online because we refused to pay for seats that I felt that already purchased or was entitled to one so I bought a ticket. When we got to the airport and checked in they did not put me and my traveling partner together meaning they didn't see them together not to mention. Our flight was delayed and we only have 4 minutes to get from gate a to gate. We got to the gate collected our boarding passes found out we were seated at the very very very back of the plane right next to the restrooms.........NICE

Arrived 1 hour early. There was no one else in line. Supervisor and assistant at desk spent 15 minutes talking to one another while my wife and I waited. After greeting us, we were told that our bags would not make it on the plane and that they might make it the next day since we hadn't arrived 45 minutes before the flight. Our bags were small enough to carry on and since I had already prepaid for checking bags online at the higher rate, I offered carry on as a solution. The supervisor stated I would need to pay and additional $40/bag. I said ok, gave her my card and she responded with "you can get that f##king credit card outta my face". Surprised, I asked if I could please pay and relayed that I meant no offense. The supervisor stepped away from the desk and said "ok, you're not flying today". I left and bought tickets on American Airlines. Don't fly 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.

If you have more questions or if you have a bad price to report to us,
