Everything was great except having to check in at Alaska. That was a surprise and took extra time and effort. Should have been explained somewhere maybe on the HA electronic ticket.

Everything was great except having to check in at Alaska. That was a surprise and took extra time and effort. Should have been explained somewhere maybe on the HA electronic ticket.

I accidentally made this purchase and they wouldn’t refund me even though I called immediately to cancel it.

The flight was delayed and they didn’t have a pilot for the flight. Seemed very unorganized and took way longer than expected.

You. Changed my AIRLINE, CONFIRMATION CODE, TERMINAL. AND GATE COMM N CATION. WAS POOR AND SUBOPTITMUM AND RIDICULOUS MY AIRLINE WAS HAWAIIN. ,THEN SUDDENLY. YOU SAY IT WAS ALASKA Give me a break,,Black is not White I could not check in over the phone...all I received was Error. And info from Hawaiian air agent saying tooooo many people were trying to check in causing the problem On the other hand I am alive

I like that you have eliminated plastic cups, bottles and straws. The crew was conscientious about separating the used paper cups from the trash. This change to paper is a great move and makes me want to choose Alaska when I fly.

Attendants seemed un-engaged and indifferent when asked for assistance.

Overall it was a good flight. The thing I most appreciated was that you eliminated plastic cups and water bottles and stir sticks and had paper cups, wood stir sticks and cans. Plus, I saw that the airline staff were actually keeping the used paper cups separate and unfolding the used cardboard meal boxes and keeping those items separate from the trash. Good for them! This makes me want to support Alaska Airlines and fly Alaska again. Thank for taking this step in working to reduce single use plastics! Kudos!

Ok but why they need to sell the ear buds?

Your Hawaiian airlines record locator number did not work! I could not check in in advance at either Hawaiian or Alaska airlines website and had to wait on long lines to check in at the airport. This caused considerable stress and I was worried I would miss the flight and thus had to arrive even earlier than otherwise. Finally, I wanted to change my flight and could not do so because no record locator was recognized for me to make changes. This was a very poor experience. Also, I could not go in and check or change my seat assignments. I was assigned a window seat, which is my least preferred location, and which I have not flown in for years. Please advise as to what kind of customer service gesture you can provide to make up for this below par experience.

Departure was two hours late! Better than four hours late on our first flight

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Very bad! No good service delayed my second connection flight

They canceled flight. Hard to believe there was even a plane incoming for us to get on

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.

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.
