Express the need to arrive at the airport more than 2 hours ahead of BOARDING TIME due to super slow security lines at the Lihue airport. 4 ppl in a party of 9 nearly missed the boarding.

Express the need to arrive at the airport more than 2 hours ahead of BOARDING TIME due to super slow security lines at the Lihue airport. 4 ppl in a party of 9 nearly missed the boarding.

I am mobility challenged and ground crew were accommodating to my needs. One must walk up a ramp to board Alaska planes. Terminal to tarmac to ramp to plane.

In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

Flight last minute delayed 2 hours for crew calling out sick

This flight was delayed but otherwise comfortable except for some turbulence. The crew was minimally engaged with us but nothing particularly bad in our interaction. The pilot was incomprehensible mumbling whenever he got on the air - honestly, impossible to understand. However, there were two flights that multiple people were trying to connect to that were leaving in 10 minutes after our flight landed (one to Alaska and one to Oregon). The passengers in the back reported to me that they asked the flight attendents to assist them in getting out first to try to make those flights- they reported that they were told that this would not occur because "people aren't so nice". NOBODY from the flight crew announced that there were people who needed to catch a tight connection and to please let them off first. I was in row 16 and when I heard this, I made an announcement myself and worked to get those trying to make those flights out first. Unfortunately, a lot of people were already in the aisles and these folks were slowed getting out. But what is wrong with the Alaska team that they wouldn't help those passengers???? One of the things I love about flying Alaska is that generally the crews are special people who seem to enjoy their jobs (despite the challenges of working with the public) and try to assist however they can. I would have liked to see the Alaska crew make an announcement to assist getting passengers with a tight connection due to the delayed flight out first. I think that Alaska often stands out because of the niceness of the crews, but this was a fail. Honestly, a huge fail. Please do better next time. I really believe in Alaska and fly preferentially on Alaska, but that means standing out from the crowd to do the right thing in being kind when we can.

The plane was in pretty rough shape-- worn down with a bit of a smell. The crew as less than stellar as well.

Kayak and Alaska have our trusted traveller information stored in our profiles. But, that information never made it to Alaska when it came time to check into our outbound flight. As a result, we were not cleared for TSA recheck. I was able to add in that information for our return flight and we had TSA Recheck on the return. I really expected Kayak and Alaska to do a complete job with our booking given the amount of information you have on file.

Not good, because they don’t serve me any drink with my meal. I asked but he said he forgot my drink again

It was an amazing experience for the first time doing my second flight by myself. Crew are friendly and they makes sure the customers meet their needs. I will use Alaska airline again for my next vocation. Thank you all for your hard work.

Flight was delayed by hr and half, takeoff and climbing was frightening

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Its good expeince but in enternteiment please be like you tube the music i like or movie

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

The crew was fantastic. They were there whenever we needed. The wifi didn’t work which was brutal on an 11 hour flight. The onboard entertainment was boring. Nothing of interest

Not really their fault, but a 4.5 hour delay is pretty brutal

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

Flight was On time and landed 30 mins early considering we were flying into Newark. No complaints.
