Get to the Lihue airport 3 hours before the flight because there are multiple security steps and extremely slow security processing. Even if you have TSA precheck/global entry.

Flight attendants were kind. Until the plane arrived and had a slow taxi. I was on the tail end of the plane and informed the attendants I had a connecting flight. They didn't do anything to help me get off in a more timely manner. Nor did they contact my connecting flight to let them know I was on my way. By the time it was our rows turn my connecting flight across the terminal D gate to C gate was already boarding. I had to run the whole way through the terminal and hope I caught a train inntime. They were calling my name last call by the time arrived at the gate. Then my connecting flight ticket would not work and a new ticket had to be issued requiring presenting my ID again

Flew first class. No headrest screens on either flight and the one flight had no foot rests either.

We tried for days to use online Alaska Airline app we needed to know what Gate to depart from . When we got there we were given a paper boarding ticket with the wrong gate on it . We almost missed this flight . It caused great stress and caused a health side effect. The previous flights April 24 started hour late mechanical issues . We were not allowed to depart plane in time to get correct gate and missed our flight .

Overall, we had a very good experience with Alaska Airlines on our flight from Honolulu to Seattle. The First Class cabin was comfortable, boarding was smooth, and the crew was friendly and attentive. The meal service was solid and the overall flight felt well organized. One thing that stood out negatively was the drink service. I was in First Class and, while quietly watching movies and not causing any issues, I was cut off after four drinks. I understand safety policies, but the cutoff felt a bit premature given the context.

I paid for WiFi but it never really worked. That was frustrating.

The kiosk was fast. I got in and got my baggage tag right away. There was a long lines at baggaged check in But it moved fast and checked my baggage with no problem. The flight was good. The flight attendants were very helpful, friendly and always smiling.

Alaska Airlines has horrible customer service. After sitting in a packed airplane for over an hour, they decided to cancel our flight and had us deplane. Instead of helping us nearby, we had to ride two trains (in Seattle Airport), from the S-Gates to the C-Gates; only to stand in a line for 3 and a half hours. Throughout the 3 hours, there was often 1 agent at the customer service counter to help the passengers trying to get information and accommodation on a flight that they cancelled. Do better!

Confusing now Hawaiian and Alaskan have merged, hard to check in - they need to uncomplicated things.

The stewards were too loud and chatty with each other

If the flight from Seattle to Eugene hadn’t been delayed for mechanical reasons we never would have made it. 45 minutes is not enough time to deplane and get clear across a big airport like SeaTac.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

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!

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

The counter service folks didn’t show up until two hours prior to the flight. The check in machines didn’t work, ALL CLOSED. Slow service, few directions. The plane was clean, but the restrooms need work from a space standpoint. I am 5’8” and I had to bend down. Very cramped and I am a thin person. Too bad it’s “profit over people” corporate mentality…
