Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.

Coffee or tea service would be nice for an evening flight, water or juice not good enough.

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

All good. Great food and entertainment when there isn’t any on a one hour flight

The flight was delayed over two and a half hours thus causing me to miss my best friend’s funeral. All because the flight crew had to get more rest. That was the reason stated. I understand however very unfortunate. Glad everyone is well rested and resting in peace.

All good except both the outbound and return flights were delayed about 1 1/2 hrs.

Not great. My flight was canceled due to a mechanical problem and I could not get rebooked for the same day. I needed to get to my destination yesterday, not today. I was able to book with another airline but it was a layover and ultimately a 1 hour flight took me 12 hours. Normally I like Alaska much more than Southwest, but Southwest came through with a not terrible price for same day.

The plane was late arriving. The Alaska people did a great job of turning it around quickly and getting us off. We took off about 35 minutes after it reached the gate.

I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines

Check-in process at SEA was very difficult, e.g., how to check-in and finding where to go to check-in. Staff that helped me was friendly. Security process very disorganized. Stopped at gate C2A to try to get on an earlier flight and four staff didn’t acknowledge me, some of the worst customer service I’ve experienced at a gate counter.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

I could not check in ahead of time. Kayak did not give me a proper confirmation number to check in.

I loved flying Hawaiian Air! We didn’t pay to sit together, but we were able to anyway. They had usb charging ports and even outlets in some seats. They served a hot sandwich that was not very good, but we were still pleasantly surprised. The staff was very nice. The seats really made my booty hurt but maybe I’m just not used to sitting so long. Also, the AC was really cold even though I was wearing pants, a hoodie, and a light blanket.

You did not have any vegetarians options for the free meal! I do not eat any meat of any kind! I asked the flight attendant and was met with kind of a rude statement like vegetarian? No we don’t have that kind of thing! Did not make me happy but made me feel like why would I want a vegetarian meal! Otherwise a good experience!

I was put in a middle seat with the people on either side of me kept passing their grandchild over me and talking back and forth while I was trying to rest or watch a movie. So inconsiderate and totally disturbing. I asked if they would sit next to each other to alleviate the constant impeding my comfort but they refused.

Late boarding, full flight. Absolutely no food and barely a bag of pretzels. No video screens and slim pickings of movies. No live tv and poor selection of shows.

Pre-Flight check-in Staff did a terrific job correcting a seat mis-assignment problem after I checked in the night before my flight. They really stepped up to make my flight home a joy. It was also my birthday, so the flight crew made me feel special a little treat.

Our flight delayed 2 hours, no WiFi in flight and the snack option isn’t great either.

I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.

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

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.

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.
