The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

I really hate the seat assignment at the gate. I understand it is so families can sit together but it caused me and others a lot of unnecessary stress and confusion, enough for me to not fly Alaska again. The app is so awful that it did not even update my seat assignment on the boarding pass but sent me a notification of my seat... it showed in Apple Wallet but not in the Alaska app itself. That only made the stress worse. I think most people like myself prefer to know where they are seated at check in 24 hours before so they don't have to anxiously hang out at the gate the entire time. This is not a good use of your agents time either to be dealing with all of us asking where we are sitting. You should automatically assign the multiple seat purchases to be together before they check in and fill us solo travelers in those gaps as we check in.

Alaska Airlines have beautiful new airplanes that have comfortable seats but tight for a tall person like myself. They do provide upgrades to flyers but at a $140 cost. My flight went smooth and prompt as well as without a hitch. The flight crew were warm and friendly as well as very attentive. I'd recommend this airline over Frontier airlines any day.

Did not like that every price option offered, even the more expensive one, required I pay for my seat. My seat was changed without my consent My TSA did not show in Boarding Pass

Boarding passes could not be received online, even after online check-in. While they appeared on the Alaska.com app, they did not transfer to inbox or messages and were not available at all on the Alaska.com app following the check-in process. There was no choice other than to get boarding passes at the airport counter.

Poor, the last leg of our trip was cancelled and we didn't know about it until we arrived at the airport. Another flight on the same airline was not available until three days later which would have ruined our vacation. Luckily we were able to get re-blooked on another airline after spending hours at the airport.

The flight was fine. The connecting flight was a nightmare. Gate change without text or email notification was super frustrating and I ended up missing my connecting flight. Return flight was delayed and had I not quadruple checked flight time, gate and refreshed the Alaska Airlines app every 5 minutes, I would have taken a flight that would not arrive in time for my connecting flight. Ended up flying Delta home.

The flight was delayed so we didn’t get into San Diego until almost 1 AM. Otherwise, it was lovely.

I always like flying with Alaska, great service and leg room

They changed our flight from a one stop 3 hour layover to a non-stop. Saved us hours and got us there sooner.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

Previously flown Hawaiian Airlines on similar routes, I found Alaska Airlines to be noticeably more comfortable. The seats on Alaska Airlines provided better support and cushioning, which made a significant difference on the long flight to the islands. When you’re spending 5-6 hours in the air, seat comfort really matters, and Alaska Airlines delivered where it counts. After comparing both carriers, I’ve decided to book with Alaska Airlines for all my future Hawaii trips. The superior seat comfort alone makes it worth choosing Alaska over Hawaiian Airlines. If you’re planning a trip to Hawaii and prioritizing comfort, I’d recommend giving Alaska Airlines a try. You won’t be disappointed. Highly recommended for Hawaii travel!

I received several emails about my 3:10 flight. When I showed up to the airport at 12:30 to check my bags I was told the flight was actually at 1 pm. They grudgingly rebooked me for a flight at 5:22 to Vegas to get a connecting to LAX. I did find the gate for my original 3:10 flight but they were booked. I proceeded to receive status updates and gate change information for the 3:10 flight, even though I was apparently never supposed to be on that flight

The crew was EXTREMELY helpful And sweet and the flight was smooth!

The Kayak confirmation number did not work for checking in the day before. I checked in at 8.30 using my ticket number. When I arrived at the airport, I was informed that the flight was overbooked, and since I had checked in late, I did not have a seat. The Next flight was not until ten PM. I called my wife, who had been taking care of our kids all weekend, and she was upset, calling me a liar and telling me to stay in SD. It turned my weekend getaway into a nightmare! I blame the Kayak website and will not book flights using your app in the future.

One hour waiting time after boarding, but arrived in time. I am satisfied

Flying with Hawaiian Airlines is a treat! They have the best crew, food and drinks! I’ve always enjoyed flying with Hawaiian Airlines and will continue to use them!

Amazing all female crew, including the pilot. Great flight attendants and smooth trip. Food was good. Boarding the plane from back to front would have made things significantly smoother. Took forever to wait for people to clear the alley. A little extra leg room would be nice also. Please thank your flight crew!

We decided to take our mom on vacation but we were worried how well she will do on the flight, she's a senior and required special accommodations such as transport chair since she can't stand for long periods. To our surprise my whole family was given priority boarding, my mom was given chair, we were not standing in line and were given seats in good area next to our mom. A+ experience!

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

After the door had been closed, the cockpit makes an announcement that catering is running late and it is not the airline's fault. It is their fault in the sense that we had to sit for 2 hours or more when we could have stayed in the terminal. Poor communications between catering and airline. This caused a young man to lose his temper and he went storming out hitting objects. He had complained to the gate agent that he had already waited at the gate 7 hours and when can the airplane leave? Airilnes do a poor job of explaining delays, maintenance issues, etc. whereas being truthful may gain more sympathy or understanding.

We were told the flight was delayed 5 times, then it was moved to the next day.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Loved the crew . Absolutely no complaints. Except for luggage lost

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

We are too tired and frustrated to comment politely at this point

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

This airline sucks. They offer low rates then charge you for everything, the app does not work well, the seats are the most uncomfortable. Maintenance issues on the flight, and you still have to sit through their credit card commercials. People are nice enough but does not make up for overall poor experience.

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
