Love Hawaiian you can’t go wrong, still provides you good drinks and little snack at the end

No tv’s. Had to walk 45 minutes to connect to next flight. Couldn’t get dinner as a result. Ended up eating pretzels until I felt sick.

Great plane, seats, and crew. Super smooth experience and delicious coffee

The pre-flight check in process was bad. The app didn't allow check-in online and forced me to check in at the airport. Alaska didn't have self-service kiosks for check in (only bag tagging stations), so I had to wait in line with people who were checking bags just to get my boarding pass.

Hawaiin airlines never let me know the alaska airlines confirmation number. it took chat and call with customer service to get that.

I think you should still be able to pick a seat at check in no matter the price tier. But the plane was decent. Seats were a little narrow so I imagine larger folks would have some discomfort but I was fine and the crew was great.

Crew was excellent......in flight medical emergency handled very professionally.....

The flight is supposed to be Hawaiian, but it's operated by Alaska. As such, I could not find my reservation on Hawaiian nor Alaska website. I could not check in on line. At the airports, even the kiosk could not find my reservation. I needed to wait in a long line to check in even though I have no bag to check. Good thing I got to the airport early enough.

Overall a great experience. The starlink internet was amazing addition.

Every customer service agent we came in contact with was rude, tired, overworked and indifferent

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Everything went as planned. Crew was great. Seats were still not that comfortable.

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.

It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
