On time, smooth take off and landing, efficient boarding. Gate staff excellent, stewardess grumpy, but civil enough.

No WiFi available. It was too late to order food also. Guy next to me was huge (not fat) so had his shoulder & thigh next to me the whole way. Plane was delayed leaving PDX due to 8 other planes waiting. Not my best Alaska airlines flight.

Check in, they should have told me that upon arrival i needed to exit the secure area and re-check in with Eva Air. I wasn't sure what to do upon arrival at S.F.

The direct service from Logan to PDX made travel so easy, I really appreciate this route. Pilots were very communicative with passengers about conditions and expectations. Everyone on staff was pleasant and helpful. Boarding was easy and efficient.

Flight last minute delayed 2 hours for crew calling out sick

Husband was new to the wheelchair accommodations this trip. What a blessing that was. All employees were helpful and customer service was excellent

Seats are still too crowded and uncomfortable on long flights like this cross country one.

Laney was very helpful. I am computer illiterate. She helped me obtain a boarding pass and preferred seat. She was warm, friendly, helpful, and smiled. I was impressed.

The actual flight I was rescheduled onto was from Seattle to Bozeman. The flight itself was fine, but due to delays/air traffic issues i spent the day hanging out at the Seattle airport and had to miss a day of work.

OUr pilot was very good and also a good landing in a very gusting Phoenix. Most important.

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.
