Direct flight from Denver to Milwaukee. Didn't have to wait on tarmac so that was a plus.

Have to pay for every little thring down to the peanuts

The staff on the flight was awesome, very helpful and kind to my friend who is terrified to fly. We were even ahead of schedule.

To pay for a carry on item is just crazy to me... not to mention you have to pay for beverages and snacks. All you are given is water.

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.

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.

I was traveling for medical reasons and the Delta crew took great care of me, made sure I was at my connecting gate on time, and even put me in a better seat on the plane. Not sure if that was a coincidental upgrade, or intentional, but it was perfect.

Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule.

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!!!!!

The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

The price was good, and it was a non stop flight.

The crew was rude and the seats didn't recline.

Boarding goes quick, nice seats in economy comfort

No free food besides pretzels on an almost 8 hour flight. Any decent seat is an upchaege to economy plus. WiFi slow, only can access entertainment if you have app download on phone.

Nice seats, very helpful staff at ticketing and nice crew

Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location.

Awesome and helpful crew

Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location. Food was not good, and drink service was only done twice on 17 hour flight. It took an hour to start taxiing after we were all seated and left the gate.

The crew was helpful and friendly, my flight was inexpensive

The seats were incredibly uncomfortable! Also, many people did not understand how to turn off the televisions, so it was pretty distracting to have so many monitors going when we all trying to sleep.

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.
