fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly...

Eddie, our flight attendant in the back was excellent. He was very kind and concerned for our happiness and comfort before and during our flight. He made the experience great. We had to deplane due to a ground delay and he made sure we had snacks and water to keep us comfortable while we waited. Overall, it was a great experience!

Flight was delayed which caused us to have to change our connecting flight. Grilled cheese sandwich was served very hot.

We were late so that was what was worst part

The Alaska app and website were not fully operational. I had to spend about 15 minutes at the counter doing things that should have been completed online. The agent was very nice and helpful, however.

Staff are helpful and patient. I don’t appreciate the almost 5 hours delay and also the delay of our luggage and being switched from one carousel to another to pick them up.

We waited over an hour for our luggage to arrive at the carousel in Seattle.

Good. They checked my bag FOR FREE so I didnt have to try to hoist it up into the overhead compartment. Also, they served free beverages, which I appreciated.

Everything was really good except it was really cold in the plane,

Delayed flight due to mechanical issues. You only serve water or apple juice which is pathetic. To get to connecting flight you need to take a train so dumb. All in all it’s certainly not about the customer is it? You make that perfectly clear. It’s the last time I fly with you no matter how cheap your fares are!

I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.

I booked on Hawaiian and was bumped to an American airline flight in a different terminal. I was traveling with my two kids and told to take an air train to check my baggage in. We were given the last three seats in front of the toilet. Never flying Hawaiian again. Totally unreliable.

The middle name gave us so much issue at check in we had done middle names when booking but Hawaiian/Alaska don’t recognize the middle names and gave us problems at check in. We have never experienced that before.

Everything was great except for the delayed flight times (it was delayed twice).

I was booked thru Hawaiian Airlines (HA) on Kayak in February. I got 2 confirmation emails from Hawaiian Airlines in February. Even though the flight ticket informed me the flight was marketed thru HA and operated by Alaska Airlines (AA), I was never given any confirmation codes or anything from Kayak or AA to check into my flight online ahead of time. They also couldn't find the HA flight number I was given on their website and was told my flight did not exist unless I searched thru the AA website for flight details that was similar to the info HA gave me. The only way to check into my flight and make sure the flight still existed required me to get there 4 hours early. When I arrived at the airport, HA desk told me to go to AA desk. First AA desk redirected me to another desk, second AA desk told me to find someone with an iPad, and finally the iPad rep was able to help me. I also had to chat with AA reps online the night previous to my return trip because the same issue occurred.

I did not board neither one of my flights because It got delayed and I had to be at my destination at a certain time

We were delayed at the SD gate for close to an hour before we were allowed to depart for SJ. Reason given was inadequate ground crew to move the plane from the gate.

Thanks to the supervisor Jose my pregnant wife and our family will not miss a very important ultrasound tomorrow. What he did was simply heroic. He needs to be promoted and praised. Please tell him our family appreciates him so so much!

Your crew shortage delayed departure by an hour resulting in us missing an event we had scheduled for that afternoon outside of Fresno.

The fact that I made my reservation with Hawaiian and then flew on Alaska really messed up my trip. From SeaTac to Omaha was awful, including having to rebook my flight for hours later because of not knowing I had to go to the Alaska check-in, thus losing time. Then I was back and forth across the airport because of gate changes that I found out about only during the final hour of a looooong day at the airport. Also, because of your system, I couldn't check in online ahead of time, either with Hawaiian or with Alaska. I feel like I never want to fly with either of you again. PS. I am almost 80 years old, have flown plenty, but do not have the stamina of a 30 year old. My phone told me I had to walk 11,000+ steps in SeaTac on the way out. It took me two days to recover when I finally got to Omaha.
