We had to take the train to our next gate but had time to eat a meal. When to our next gate and asked employee about gate and got informed that gate had been changed so back on train to next gate. So thankful she was there and informed us of gate change. Because of the issue the boarding was slow but employees were there and busy helping all and keeping it organized.

Very pleasant and the flight felt like it went by quick

All flight entertainment is from your own device and there was an $8 charge to connect. also 1 drink and a small bag of pretzels was all that was given to us. other that that the seats were good and the flight itself was as expected.

It is very bad they do not give you money back

They lost our bag and it took them days to find it. Terrible communication and lots of lies about where it was. Their system hasn’t merged with Hawaiian yet they route people on shared flights with Hawaiian, creating an administrative nightmare.

Major flight delays, it was a 1.5-hour delay. The gate kept changing about 3 times in Seattle. very hectic and chaotic.

More leg room in back seats. Can you require people to smell good on planes? ha ha Staff was great! Plane was comfortable. I enjoyed the movies and TV. Smooth take off and landing.

The only problem was the time delay. Kudos to the counter agent in Seattle. Very helpful and gracious.

This flight was how a flight should be. The flight from Hawaii to Seattle was terrible

Quick and easy check-in. Love how technology has helped speed up the flying process. Smooth flight to a Seattle and back. 10/10

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

I am very bothered by the events today. I can't believe the flight attendants allowed someone to take my seat and made me move. It was embarrassing. I was in the right. The lady just didn't want move. I can't believe delta would allow this to stand and disrespect my rights as a passenger. The lady complained about her leg and that she couldn't move. Firstly somehow she was able to make it to row 24. Not sure how much her leg could have hurt. Secondly, I'm in plenty of pain myself. I just finished chemotherapy a several weeks ago. My body is constantly sore. Yet deltas flight attendants didn't appropriately protect my rights. In the end they found me a seat on the plane but I want to understand how delta can operate this way. They in essence allowed a bully to get their way.

Flight was canceled with no voucher of any kind and next available flight was two days later.

Boarding was chaotic. Microphone not working properly and second agent was distracted from task with baggage and late arrivals.

I DID NOT GO TO HAWAII ON HAWAIIAN AIRLINES. YOU DID NOT INFORM ME THAT BY CHOOSING BASIC ECONOMY, I MIGHT BE REQUIRED TO FLY STANDBY. I AM ELDERLY AS WAS MY COMPANION WHO IS ALSO SEVERELY DISABLED AND THERE WOULD BE NO WAY WE COULD TRAVEL ON STANDBY. THEY TOLD ME THAT ALL OF THE BASIC ECONOMY SEATS HAD BEEN SELECTED BY OTHER PASSENGERS AND WE HAD TO PAY AN ADDITIONAL $942 TO GET A SECURED SEAT ON THE PLAN AND, IN SPITE OF THE ADDITIONAL COST, WE WERE NOT ALLOW US TO AMEND OUR TRAVEL PLANS TO EXTEND OUR VACATION. ULTIMATELY, THE FLIGHT WAS DELAYED. WE WERE OFFERED A REFUND IF WE CANCELED OUR TRIP ALTOGETHER WHICH WE DID. IT IS YOUR DUTY TO INFORM YOUR CUSTOMERS OF THE POTENTIAL PROBLEMS THEY MAY FACE, AND YOU DID NOT DO SO. I WILL NOT UTILIZE YOUR SERVICES EVER AGAIN.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

the people at the counter, NEED TO BE MORE HELPFUL. we had three suitcases to check in and we were not trying to be an INCONVENIENCE TO YOUR clerks. but she was not helpful and made our trip back home memorable but not IN A GOOD WAY. Sadly to say, you guys need to teach to be and to go above and beyond to help THE CUSTOMER BY ANY MEANS POSSIBLE. they need to leave aside whatever they are going thru in their lives, THEIR WORK DEMANDS THAT OF THEM, IF NOT THEY ARE NOT IN THE JOB THEY SUPPOSED TO.

Because the airport is under construction and because Hawaiian air just changed terminals we missed boarding out flight by 5 minutes. That cost me a night in an airport hotel and several hours of rebooking to make it to my destination. Costumers need to know that airport construction is a problem and they need to add an hour to deal with the air train delays from Federal Circle.

Half of my family members didn’t make it because they involuntary bumped off . And their seats where given away

Hawaiian Airlines staff is always professional & quick & easy check in & boarding process

Customer service by Susan of Alaskan Air was outstanding. We missed our flight out of JFK. She got us rebooked the following day. Way to go Susan.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

The flight was 2 hour delayed, otherwise everything was excellent. The delay was due to the hourly limit requirement so given that as a reason, I'm happy with the flight!

Weather delay for 2.5 hours followed by half hour crew delay, did not have ginger ale, uncomfortable seats

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

It’s a great flight. Service is good. Staff is awesome.
