Pros: Crew was nice and professional. Bags arrived in tact in the right place and so did I.

Cons: The corner cutting is starting to cross a line. I had so little room that my knees touched the seat in front of me and I couldn't grab my bag below the next seat without disturbing the people next to me. I didn't pay to request a certain seat, so I was in the middle seat of the last isle for each flight. The "free" entertainment was ads to purchase entertainment. Obviously they now make you pay a about 20% of your ticket cost to bring a rollaway now.

Pros: I liked arriving home in a timely fashion.

OR the Mother Superior flight attendants that couldn't wait to point and nag about seat backs and tray tables. I wonder if either of the women noticed they were talking to someone who wasnt't an English speaker? United needs to fly Southwest to learn the right way to do things.

Cons: We were delayed in Chicago due to weather coming home from Europe. We were not allowed to use the business class lounge even though we paid for business class tix. My family is still sitting in the airport waiting on their flight to dallas. We have been up now for over 24 hours. We should be allowed to be someplace comfortable for the price of the business class tickets. poor form on Lufthansa’s part.

Cons: This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane.

Pros: Nothing was positive while using Frontier Airlines

Cons: Everything was pretty unpleasant: 1.) hidden baggage fees ($45 round trip would be one thing for a CHECKED BAG, but $90 collectively for the round trip is FRAUDULENT) Especially when most airlines don't charge for carry on bags or it's at least calculated in the final cost. At first when I booked this trip with FRONTIER $180 for my tickets looked like a decent deal, UNTIL I WAS TOLD AT THE COUNTER THAT I HAVE TO PAY $45 each way for a FRIGGIN CARRY ON BAG!! turning my reasonable and anticipated $180 trip turned into almost a $300 (NEARLY doubled my cost!) had I known I could have at least packed more into a checked bag for that price. 2.) my flight was delayed 4 hours on my outgoing flight, cutting into my personal time off and no compensation or even a kind gesture like a free McDonald's sandwich when you land...you guys really have poor quality and seem like you don't really care about the paying customer 3.) staff seemed clueless and didn't know how to answer customers questions as to why our flight was delayed!! 4.) mechanical issues with plane were the cause, or at least that's what the copilot or captain Just HAD TO MENTION TO US RIGHT BEFORE TAKEOFF, causing everyone to stir and raise eyebrows. 5.) to top off him mentioning the mechanical issues they were having with the plane the flight was rough..I've never been more tense or anxious on any of the other 30+ flights I've taken in my life. Pilot didn't seem to know how to handle turbulence.

Pros: Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights.

Cons: Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours.

Pros: The flight attendant finally took care of it after I complained a couple of times.

Cons: That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions.

Pros: O'hare airport.

Cons: I was unable to print a boarding pass at one of the many kiosks - it informed me I needed to speak with a Frontier agent. The line for the agents was about 2 hours long, too long to wait to make the flight. After being told by a frontier employee that I'd just want to get in to the line to rebook on a later flight (9 hours later) I proceeded to speak with a momentarily vacant agent who, helpfully, printed and handed me my boarding pass. I arrived at the gate to a closed door and ended up needing to rebook anyway. I decided to just not go on the trip.... wasn't worth having to deal with Frontier 2 times in one day.

Pros: Well I liked that I got there and that the price for the flights in total was $190 (kayak SLAYED at getting me the right price). But I was expecting a continuation of excellent service that I got in white planes New York to continue, and be elevated, because they didn't have the same troubles that my previous airport did.

Cons: There were just too many failed opportunities. The biggest was the gate agent who was "just filling in for another guy who's suppose to be here." I'm like well if someone is in line, even if they hop in line, you need to give them the best service because you're the face of the company.

Good 6.0

Pros: I feel like there is more leg room in the seats then in other discount airlines! I like the snack and drink, this breaks up the flight a bit. This is nice for me because I don’t like to fly.

Cons: The staff seemed miserable. No one was nice or even smiled. Just felt like they couldn’t wait for this leg of their day/trip to be over.

Pros: Crew was great. Planes with built in TV was even better.

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.
