I appreciated that the staff went out of the way to make sure I was taken care of.

Terrible. Would never fly again. Took them several hours to prepare the plane and and reached my destination 4 hours late.

Our boarding was delayed due to two flat tires, but I appreciate the focus on safety. I also appreciated the additional offerings for drinks which never happened before except on Hawaiian Airlines. The hospitality is fantastic! Glad I upgraded to premium seats for the extra leg room as I was getting frustrated when the person in front of me was very restless and kept shifting. Otherwise, it was a fantastic experience.

Had to sit and wait to get off the plane for closeto a hour. My son also flying to a different destination that day also had like a 2.5 hr delay

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

Could not check in online - had to get boarding passes at the ticket counter and our daughter got bumped off our connecting flight. NOT OK!

I needed more space to sleep on an overnight flight.

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

Wonderful respectful staff for a short flight late at night...lots of considerations all met!

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

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.

After being assaulted by a flight attendant I was then brushed off as oh well because he long braids didn’t mean to whip me in the eye. I have filed complaints and will see. But like any other issue I’ve had with kayak involved it’s been trash. Last time I’ll be using your app

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.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

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.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

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..,

They we able to seat my companion and I next to each other. Plane’s temperature was very cool. Willl be more prepared on return trip.

What an amazing flight. I haven’t experienced this level of service in a flight in years. This will be the only way to fly to Hawaii for me in the future.

Love you guys are so friendly and kind and wonderful

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.

Hawaiian airlines has awful customer service. Told me to keep a flight I wasn’t boarding, instead of rebooking me under two separate reservations, which caused my whole reservation to be canceled. Major issues with leadership and management. The staff at Hilo was reluctant to give me a refund, so I had to by a first class ticket in order to get on a flight the same time as my partner. The blame was pointed at me without sincere apology until the supervisor came out, who also apparently had no authority to refund me. Still waiting on correspondence from the airline days later.

I could not believe that on a 5 hour plus flight we were not given a complimentary meal . That should be illegal. Or it would be nice to be informed beforehand that a complimentary meal would not be provided. The wording in the email I got about pre ordering food was phrased in a way that made the food seem like it would be free. Very misleading! Also during boarding we were informed there would be empty seats we could move to if we wanted, all we had to do was wait for an announcement, however an announcement was never made. Then when we tried to change seats ourselves we were singled out over the loud speaker and told we could not move without asking. Then the flight was about to take off , so we didn’t have time to ask . Then we were told we could not move to the exit row because you had to pay for those seats, but we were not told where we could move. Also no one was in the exit rows so , if something happened no one would be there to assist the passengers. Also people should be allowed to move there if the airline wasn’t able to sell them. One passenger asked if he could pay for the upgrade and the flight attendant said she did not have the capability to charge for the seat on her mobile device, so the airline ended up losing possible income anyways . So why not let people move there during flight if you have no way to charge them? Then the landing was bumpy and awful and many passengers complained out loud when we landed .

The flight was great! The flight attendants were friendly and attentive. I would definitely fly Hawaiian Aurlines again!

You have to buy the ear buds and they only offers little cup of water twice.

Flight was on time, crew was friendly and prompt with the service. The only thing that could be improved is the seat space, but that's wishful thinking

Cons: Rode a newer Airbus - had the same rattle in the panels above my seat (plastics not secure b/t lighting and panels) as the last Airbus I rode. Cabin was quite warm, borderline hot. Asked to pay for headphones. And the reason I am writing this - when we arrived it took over 20 minutes to get our door open due to nobody on the ground ready for arrival. Likes: Staff was friendly, helpful, and professional. Sandwich was quite good.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

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.
