The aisles were very narrow for passing and too long to get to the restrooms. You asked to check carryons at boarding, but the bag was not at the luggage carousels on arrival and no information given as to where to pick them up.

The aisles were very narrow for passing and too long to get to the restrooms. You asked to check carryons at boarding, but the bag was not at the luggage carousels on arrival and no information given as to where to pick them up.

I truly can’t give a review regarding the food or entertainment it did not apply to my flight. But everything ran very smoothly.

I had the worst seat neighbors thry literally snored so loud and the man next to me man spreaded the whole time i couldnt sleep

Why is a fanny pack considered a third carry on? This shouldn't be regulated at the gate

The crew in first class did an amazing job keeping me comfortable, well fed and with plenty to drink. They work hard and deserve to be recognized

Mid flight we were bothered by a bee. Kind of odd, but a bee allergy made it a bit stressful. Attendants passed by our aisle during service multiple times. Otherwise, it was fine.

The airline said get there three hours before the flight if you do not have the new Real-ID. Except nobody is at the check in desk and i had to stand in line for 30-45 minutes for somebody to start checking in/accepting baggage.

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.

I was unfortunately placed in the middle seat. Very, Very cramped.

I have to eat gluten-free due to celiac disease, but so far no Alaska Air flight has offered a gluten-free option for the snack given out with free drinks. It seems like that wouldn't be too hard to do.
