Cons: The flight was first delayed from 10:40 pm to 11:20 pm. After boarding to leave by 11:20, the pilot announces they have a problem with a seat belt in the cockpit. This leaves us grounded till 1:00 am. The crew didn't lower the lights in the cabin so people could sleep, and this was due to "policy". If I can avoid it, I will never fly with Frontier again. What a disaster of an airline.

Mediocre 2.6

Pros: Seat was okay. Flight Crew was okay. I got where I needed to.

Cons: Either Frontier or the third party I purchased my ticket through on Kayak (Kiwi.com) sold me a ticket as if it were a complete flight from point A to B with a layover in between. In reality however, it was two totally separate flights which required me to go to the Frontier ticketing counter upon my arrival at my layover destination, get a ticket printed for my second flight, pay to recheck my bag a second time ($45 x2 = $90 which was total BS), go through security again (also BS) only to walk back clear to the other side of the airport where I just was. To top it all off, our flight took off late and upon arrival we didn't even have a jet bridge available. So, all of the passengers had to get off on the tarmac and wait to be bussed from wherever we were all the way to the main terminal. Then they switched the baggage claim caracul on us. What a mess. This will probably be the last time I buy a ticket on Kayak, Kiwi and possibly even Frontier.

Cons: I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER.

Pros: The flight crew was very competent and welcoming.

Cons: The gate agent at JFK was annoying. She forced us to check carry on bags for no apparent reason. Much larger carry on’s were allowed both before and after us. Her fellow agent seemed like she wanted to apologize for her capricious behavior, but was understandably hesitant to do so. The airplane seating was cramped and uncomfortable. The rntertainment choices were very limited unless you enjoy superhero movies or a very limited range of audio/musical selections. So it goes in coach class.

JFK
SEA
Excellent 8.0

Pros: The flight was not even 1/3 full, which made everything easy. Was able to find a spot for my bad above my seat. The seats next to me were to empty, so that added benefit through out the flight. The in flight entertainment on the app is a not annoying if you don't download it first but there's a work around if you know it.

Cons: Minimal food selection.

Mediocre 2.0

Pros: Nothing

Cons: Out of the four frontier flights I’ve taken in the past six months each one has been delayed for some reason. First one was over an hour late and caused a majority to miss connecting flights. Today’s experience was not a whole lot different. First leg of the trip was behind schedule, second was delayed at the terminal for the “cleaning” of the aircraft. I will walk to my destination before ever flying with frontier again

Okay 4.6

Cons: Flying from New York to Atlanta on business class there was no access to the lounge because I was not flying to Lima on the same day. I bought the whole international business ticket to Peru together, I don't understand why Delta consider my first portion not part of my international ticket!

Mediocre 2.0

Cons: I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER.

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,
