My flight wait is 3 hours delayed due to Unknown reason. We waited a very long time in the tarmac. Our flight 24 was scheduled @ 7, therefore we left my house at 330 to park our car. We were at the gate @ 530, then we were told at 6a that it will be late , we boarded at 930 but did not take off until 1015. Therefore my arranged pick up in JFK was cancelled because of no show. Before all these I got an email offers of changing my flight to a different date which I took a day earlier. I will never again take Alaska Airlines, very Inefficient and Disappointing.

Such great crew, from checkin to the plane. So friendly and helpful, I was genuinely impressed.

Seats extremely uncomfortable, no entertainment, no snacks, and when boarding, half of the passengers needed to check in the carry on luggage without any explanation.

The flight was jumping between being delayed and closer to schedule about 5 times. Alaska air website showed incorrect times while google had latest info. This panic was horrible to deal with.

I always heard this was a terrible airline but I was happy to experience otherwise. The seats were more comfortable than delta. They did board late and gate was a little chaotic, which is to be expected for a budget airline. I would definitely do it again for that price.

Very expensive for short flights. Can’t communicate with Alaska Air about passport issue at check-in. Also no replies to my text messages. Wanted to extend our vacation for two more days but this expensive flight ticket is called SAVER and I couldn’t make changes or cancel or get a credit even, so I paid another airline for the return trip. Extremely disappointed.

They canceled my flight then changed me $155 for the same flight the next day

Our flight time was drastically changed which caused us to lose a day of vacation

I like the new adjustable headrest. Unfortunately 2 crying children were in front of us. But it was the first time and not holding Alaska accountable for that. Alaska always seems to have everything in order professional but comfortable.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

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.

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

I would have liked to arrive on time - not 5 hours late!

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Delayed and took off even later than the scheduled delay time

My husband upgraded our seats and I don't know if it was due to the type of planet was or if they didn't upgrade our seats. We were supposed to be in I believe comfort seats and they were just as tight as any other seat- no leg room and we are very tall people but at least it wasn't extremely cold. My husband did put in a complaint about our seating because he paid extra and if we would have known that the space and the tightness would have been the same, we just would have gotten the emergency row emergency row seats that we normally get. We love Delta but both our flights coming home we're not good. Oh I forgot to mention that on our flight to Hawaii our luggage wheels got broke and we had to purse new luggage on vacation then we never had this problem so we didn't know protocol and reported it after we got home only for them to tell is we only had 24hrs to report the damage. Not sure what was going on with Delta this vacation trip.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

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.

The entire crew had everything handled and truly worked together. More than once, I saw them hustle down the aisle and back just to serve customers.

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.

The flight was great. But the problem is we actually booked a flight with Hawaiian Airlines. We even received a Hawaiian Airlines confirmation number. So this made it really difficult to check in the online. So I had to call Hawaiian Airlines to get our Alaskan Airlines confirmation code to check in. Also weren’t told we were flying on Alaskan, but once we got on the plane, everything went well!

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

Agents talk too fast over intercom. I know it’s memorized and we’ve all heard it before. Just slow down a little. Stop charging for checked bags. I was pleased to get my bags promptly at each end of my flight.

It was clean and the crew was great. I wish the chairs could recline just a little more and you would provide small pillows for people with bad backs. My back is fused and a little support would be great.

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.

I’m not gonna fly Frontier Airlines because booking is not an option. No water or food is for high price, not equipped for health emergency incompetent crew for emergency services. Cheap airline shows it is cheaper in all service categories. Boarding is the best of all airlines!

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 never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.

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.

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.

It was a short flight so no food or entertainment….

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.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous
