The crew was very attentive, boarding was orderly. I really liked the way Alaska Airlines gives boarding passes and dropping off my bags. Very smooth.

We never had an experience on Alaska Airlines. We missed our flight .

Overall, once we took off, our flight was good. Flight departure was significantly delayed due to mechanical issues. Upon arrival, it took wayyy too long to retrieve checked bags.

Wifi would be nice. Unfortunately the particular airplane was not equipped with wifi.

Seats very comfortable and legroom appreciated. All in all, it was a great experience.

Had to go in the bus to board the flight. Was traveling with just a carry on, but Carry on luggage was recommended to be checked in and it took a while to come to the baggage claim.

Everything was good. The flight attendants were great. I was disappointed that there wasn’t any screens on the back of the seats to watch movies, tv, etc. I only had my phone to watch movies on.

Ok I answered this already. Because it was negative did your AI Analytic Expert not submit it? Flight was boarded 35 late for supposed "maintenance" yet the crew calling over the P.A. for 3 separate individuals. There is NO food. There IS no entertainment. You charged me for checked baggage, then don't charge at the boarding area?! Shame on you for becoming Spirit Airlines. I thought you were better. At least you were at one time.

The return flight from Atlanta never has the same Alaska Spirit that every other route does. It might just be the fact that they live in Atlanta.

The Flight was late- Lost Baggage Still Haven't got bags. Dont know if I would fly Alaska Again

The flight was over 2 hours late.. once we finally got boarded things were fine

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

Flight was delayed for about an hour but overall good experience

Flight team was great and we even arrived ahead of plan!

The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

Flight was delayed but it was very smooth. Crew was very nice. Seats are uncomfortable but ok.

They didn’t offer a water, even after I asked

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.

I loved the staff on the plane. So friendly and helpful! However, there was an argument and misunderstanding by the staff and a customer at the gate, and the staff member was being unprofessional. When we arrived in Atlanta, we waited 1.5 hrs for our luggage to arrive. When I asked the airport attendant, they said Frontier had the longest wait for luggage out of any airlines, and that they could not be held responsible for the delay.

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
