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.

It was a great experience, although our seat was taken and we did not want to be rude and ask the person to move. Flight Attendants need to make sure that people should be in their assign sitting that are paid for. Other then that, we had a great flying experience with Alaska Airlines.

Too many people with oversized carry-ons. Uncomfortable seats. flight was too crowded.

Assigned last seat in row Did not recline at all Alaska Air seemed to have more leg room than my last few flights on United Yay!

The WIFI didn't work well enough to get through even 5 minutes of a movie I had selected (it just kept pausing and spinning), and I just gave up and read a book. The selection of movies was a little sparse though, so reading wasn't that bad of an option. This was an older 737-800, with undersized overhead bins -- but it doesn't make sense to me that we are told to slide our bags in with the wheels facing us (most people ignore that and put the handles facing us). This makes it more difficult to remove the bags (no handle). The flight went well, and the fruit/cheese platter I pre-ordered was good -- although it is a little annoying to have to pre-order for this (but I suppose it saves time). When I pre-order it automatically gets charged to my personal credit card (Alaska VISA), when I'd prefer to use my corporate card for that on business trips.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

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.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

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

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.
