They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

After landing in Seattle, 3 hours waiting to find parking space do to driving problems. Very uncomfortable.

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

Never got on because first part of trip was cancelled and we have no idea when we will get rebooked…

They cancelled the flight and provided no support to find another way home or how to get a refund. Links provided didn’t work and phone wait times were over eight hours. Battery on my phone couldn’t last long enough.

signage from the upper area to the tram down 2 escalator!

The WiFi worked for entertainment but a nearly 4 hour flight should have personal tvs

Generally very good. Waiting (due to de-icing and traffic) in plane to take off was a put-off. But it's not the airline's fault. I find Airbus more comfortable than Boeing.

Lot's of good food and free entanglement made the trip pleasurable and fun.

The food was terrible, worse that what you get with UA, an already one of the lowest standards to beat. How cheap one could be, providing that kind of junk food in first class. Unbelievable! The seats were not very comfortable either. And there were no screens either, not that I cared much but for you to know.

The WiFi was not working. That made for a long flight.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Flight was delayed due to crew being not on time

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

bulkhead seat had very little legroom - even in bsiness class.

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

Timing, quality of service, promptness and courtesy of the staff

There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

No charging outlets worked. Other than collecting trash attendants didn’t come around. No one could hear flight attendants announcements during the flight. Seat pads were horrible. Sitting on a board for 5 hours. What happened to Hawaiian airlines comfort, hospitality, and extras? Our pilots did an excellent job trying to minimize turbulence and incredible job in landing in windy conditions.

I like that if they asked you to checked in a bag at the gate they give you priority to board

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.

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.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

I like flying first class, and United has a nice one

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.
