You no longer give receipts for baggage at the counter. And it is next to impossible to get it on your webpage. Spent 20 min trying and gave up... I need receipt to submit for reimbursement and don't have time to waste on your poor webpage Disappointing .....

The flight attendants were unkempt and show no customer service skills. They avoided eye contact. There were no smiles and they were dismissive and snarky.

Complete flight rebooked and 6 hours delayed. Zero accountability from the airline or Kayak for the issues and I’m injured which is why I opted to pay more to fly than drive because it’s painful to sit or stand too long. What was supposed to be a 3ish hour travel day turned into a 9 hour excruciatingly painful experience that has left me in worse pain than when I initially started.

It was a good flight, short so there was no food or water service

Checking in very confusing compared to Hawaiian Airlines - much simpler! Front checking in at airport can improve. Hawaiian service always gives the extra mile, with a smile. Alaska can use and spread the Aloha Spirit. Mahalo nui loa Thank you 🤙

Plane was delayed getting boarded and then again delayed in take-off order. Alaska Airlines must have very little clout at JFK so they don't get priority treatment. All the delays meant we missed the last flight from Portland to Eugene. Alaska did give us hotel voucher for the night...but sent us to a downtown Portland hotel rather than to a nearby airport motel which made for a longer ride at night and then again in the morning. Just made an already long, late night even longer. Hotel was an old outdated Hilton in a slightly seedy part of town. Alaska gave us Lyft vouchers for getting to the hotel, but the return voucher for getting back to the airport in the morning didn't work.

Not a fan of a 5 hour delay. I received a text from Alaska Airlines advising I would get a $100 travel voucher via email. Several days later I still haven’t received it.

My email notifications were silenced, so I didn't get word that the departing flight had changed gates. It wasn't until I noticed that few people had gathered for the flight that I checked the airport schedule board, 20 minutes before boarding. I then told several people at the old gate of the change. If I was to receive a text I would have been notified of the change earlier, Or to hear an announcement over the airport intercom.

Canceled flight. No communication of this prior. Rescheduled to next day. Our good seats we purchased months ago turned into last row middle. No apology, reason, nor compensation for time and $ spent.

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Southwest's seats are the least comfortable I have ever sat in.

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.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

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?

Our flight was delayed, which I know things can happen. The bathrooms were dirty and a mess. It took over an hour to get our bags after the plane landed. Every flight was on the same 2 baggage claims. You would thing if we spent over 5 hours on a flight we would get more then a tiny bag of pretzels. The movie and tv choices were mid.

The flight was very smooth and the landing was AMAZING! I have flight anxiety and it didnt peak once! :) Thank you to the pilots and crew!!

Pillows and blankets were nice since it was an overnight flight, but the seats should be larger and there should be more space between rows so we have more leg room.

It was a great flight and nice experience. Would fly Alaska airlines again!

Alaska airlines is not what I expected Very disappointed Unfriendly Discouraging Very bad customer service, heartbroken trying to explain to them my situation.

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.

A second drink service on a 6 hour flight would have been helpful.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

The flight was comfortable with the exit row and great service

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.
