Lights turned off at night, not a lot of announcements to disturb sleeping passengers. Plane was clean. Crew seemed fine enough.

To begin with, a three-hour delay on what was already just a four-hour flight, and no steps made to even offer snacks or discounts or other amenities to apologize for the gross delay. Very uncomfortable seats; even dead tired, I could not get much sleep. I usually use the food tray as a place to rest my head, but it was far too small to use for that. Upon landing, another 45 minutes of delay as we waited for our gate to become free, and again, no measures taken to apologize or make us as customers feel like they wanted us to feel even a little bit better about the situation. I get that it's a cheap flight option, but even so, the company needs to take more responsibility for its internal problems.

Plane arrived early

They board the front of the plane first, meaning the aisles get clogged up slowing down the process. Also, staff kept insisting pre boarding that more people needed to check their bags because there wasn't enough overhead bin space, but there were plenty of bins not full by take off.

We were traveling with a toddler and infant but put in different row because the tickets were purchased separately. Gate staff promptly put us together and even bumped us up to delta comfort. Was a very pleasant trip. Thanks delta!

Tough! other than the only flight available for the time, I would not have chosen it.

Extremely commercial in the name of budget airlines! The flight wasn't cheap or anything! But money speaks everywhere and ALL the time with this airlines. $2 for a can of soda. Carry on bags- pay! For whatever reason you decide to buy it at the airport- extra! Seats- very uncomfortable and you couldn't get better even if you paid because the whole flight has the same kind! Use this airlines at your own discomfort!

Well, this flight was a disaster. It already was a redeye as we were going to get into Chicago at 5:00am. But then our flight got delayed 3 hours in Seattle due to "technical difficulties" and we didn't touch down in Chicago until 7:45....then you know what happens? The flight doesn't have a gate because we were so late, and thus we had to wait in the plane for another 45 minutes. It was at this point frontier emailed me a voucher, which I was fine with....but then getting my luggage (which you have to pay extra for to be checked in) was shredded entirely on its side, as if they had dragged it on its side. Nice service.

Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league.

Honestly the WORST experience ever with a flight. Angry Kayak doesn't post the cost of luggage and carry one with them. Flight delayed 5 hours for non existent weather, leading to 1 hour sitting on the tarmac because they didn't have a gate at the largest airport. Then, they destroyed brand new luggage.

I hated the whole thing. Seats and tray tables are a joke

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
