My Alaska Airlines return flight, although worked out in the end, didn't start off well. The initial plane that my family and I boarded was grounded because of a mishap that happened to one of the engines and everyone on board had to disembark the plane. Thankfully we were accommodated with a another plane but our initial flight was supposed to have departed at 11 pm San Diego time for Orlando but instead we ended up leaving at 1:40 am San Diego time. All Passengers were informed that part of the delay was that the plane had to be inspected by the captain, the food had to be stocked and the individuals responsible for fueling the plane left for the evening and had to be summoned to return to fill up our. The Alaska Airlines crew at the airport and on the plane were awesome and apologetic. I know that the crew wasn't responsible for the mishap of the engine but I think in the future the airline should offer a complimentary drink or (1) item of food other than pretzels, nuts or chips to all passengers since we're not to blame for the extreme set backs. The airline in general is good and I recommend to all flyers.

Late leaving so threatened our connection in Vegas to Seattle. We did make up time and made our connection.
Dropping off of the checked bags took way longer than it should have. The agent for the pre-tagged and ready to drop off line was gone and didn't come back for about 15 minutes. The other bag check lines were barely moving. Agents were standing around and not much was getting done. Everything else about the flight was great.
Was late but $50 voucher was great benefit of the summit card.
See previous. It was the flight from Honolulu to Kapalua that was cancelled.
I’m not sure there is anything that can be improved, even the cost was fantastic.
I truly appreciated the kindness and attentiveness of the staff and flight attendants. They did their best to be prompt with departure times to San Diego and back to New York! Alaska Airlines ... you are awesome!!
I've never flied them before but liked them. Weather was bad so a little scarey but they did a great job landing.
It was all good, no delays which was a worry. All great
I recently traveled with my service animal, and before boarding, a gate agent kindly arranged for me to have an empty seat next to me to give my dog more space. However, once on board, a male crew member spoke to me in a rude and loud tone, insisting my dog stay on the floor or my lap—even after I explained what the gate agent had approved. His tone and behavior were unprofessional and made me feel uncomfortable in front of other passengers. I understand and respect airline policies, but I would appreciate if this could be reviewed to ensure better awareness and sensitivity toward passengers traveling with service animals. Thank you for your understanding.
We got exit row seats both flights. Everything was running on time
The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.
No delays and arrived to destination 30 min early. Staff was super friendly.
San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.
Everything a cheap airline should be at normal airline rates.
Full cans of soda would be nice. A choice between two snacks would be appreciated.
Tried watching free movie and it kept freezing so I couldn’t finish.
I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.
No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.
Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.
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 food options were limited and very specific. Some type of entertainment option for a 4.5 hour flight would have been nice.
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.
comfortable but the food is horrible. I have flown Hawaiian several times now and no matter what they say the food is its the same squashed bread with melted goop inside. Tastes fake and isnt what they represent, its quite nasty. What happend to real food? And there is NO entertainment!! so not sure why they are asking for a review on that.
Good and friendly staff. Nicely enjoyed the complimentary drink and snack.
I was very, very cold and a stranger loaned me her sweater next to me. I didn’t wanna buy a blanket just for a four hour trip when I did not need the pillow or the earphones. I don’t mind purchasing a blanket, but I only needed that not all of it accessories. Cold air pretty much blew the entire trip. Two people in front of me both bought the blanket packages. Maybe that’s the idea. The crew was exceptionally nice and passed through multiple times.. the restrooms were very clean and usually accessible.
3 hour wait on customer service after flight was cancelled. Was bumped to a flight where I wouldnt have gotten to my destination for another 2 days. Had to fully refund flight and book a new one the following morning. Paid twice the amount for the flight than I had originally booked. Very disappointed I was not offered any sort of discount or points for all of the frustration, in fact the airline profited twice as much off of me by cancelling my flight and and changing my entire trip.
I understand that both Hawaiian and Alaskan are in the process of merging but I could not get real-time flight info or access my boarding pass on either app
Had a hard time checking into my flight on my phone because they gave me the wrong confirmation number. Otherwise everything else went well.
All was good and they were able to seat my travel companion next to me. Thank you.
The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?
Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.
Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?
They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.
Our flight from Eagle to Vail was delayed to the point we missed our connection to Savannah. Now we’re a family of 4 in a hotel room with luggage, no toiletries, no clean clothes. Gate attendant said the delay was mechanical but it was put in the system as something else so no compensation. That’s just wrong.
I take this flight about 6-8 times per year. It is convenient and saves an hour or two by skipping PDX, SEA, PHX, or ORD (but it takes longer to get bags to the carousel than Alaska Airlines). I wish the food service were better (but they might cut back on it because it is a red-eye). The WifI seems to go down about an hour out of Anchorage, and then comes back about an hour later...so be warned if this is an issue for you.
WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.
Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk
The entertainment package was vast and the selections were very current. Keep updating it was great.
The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.
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.
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.
baggage clamed had to wait over a hour and half for all people on my flight it was terrible
My flight was canceled I was promised a reginf still not received.
The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.
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.
Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
