The flight was great. The pilot was great. It was really annoying that the staff had facemasks on. Hard to hear what they’re saying when a mask is covering their mouth. I enjoyed the flight, but there was a crying baby in front of me. You guys should offer flights baby free. I would be very into that me and the person next to me discussed how they should make free flights for all of us that don’t have kids. I wouldn’t mind paying extra to not have to deal with the smell of a dirty diaper or screaming of a child. Also, if they had a separate room, the babies could be sent to the back with a curtain or something muddle the horrible sounds.

Smooth. Courteous. Fun. One problem: the wheels on my checked roller back were broken when I picked up baggage at destination. Must have happened during flight baggage handling but I don’t know where.

Staff very helpful and friendly, in flight entertainment poor. Flight left late and thus arrived 20 minutes late to final destination.

First time flying with Alaska and the staff were All professional from checkin to departure! I do plan to book more flights with Alaska. Thanks

Boarded the plain and had to wait 1 hour for crew Captain to arrive from another flight

Overall good flight, smooth and on time and comfortable. Disappointing that food is not served and you can't purchase the snack packs on the plane.

There was a row with three women who were very loud - talking and laughing. In an open, outdoor setting that's fine. On an airplane, no. The flight attendants told the women they were the fun row. It took the woman sitting in the row ahead of the loud women to tell them they were too loud, but everyone in the general vicinity was irritated. I didn't think it would be possible to be so rowdy for so long. Then when we landed we weren't let off at a gate. We had to be bussed in and the bus contended with airline traffic. After dealing with the loud passengers, this was not what I was expecting. An incredibly disappointing experience with an airline that I have always regarded as one of the better ones.

They oversold my flight by 9 seats so when I went to check in I was not assigned a seat and the only one available if I didn’t want to chance it were 100 dollars more

Was not happy that we had to wait an additional 50 minutes for passengers that were still in TSA. This delay made us miss our connecting flight in Seattle to get home to tuck in our two little toddlers. We ran off the plane and ran across the entire airport trying to make this flight only to get to the gate to see that they have ended boarding. So they were willing to wait for passengers in Hawaii but not Seattle?? Especially when this wasn't even our fault. I expect to receive miles for missing our flight and spending an additional 4 hours in Seattle.

Better organizing of entry and exit onto the plane regarding all of the baggage people haul on. There should be a better system so those with no baggage can get in and out more quickly. The baggage haul-on situation is absurd.
