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.

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!

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

Re-checking our bags, the workers were not able to help us with boarding passes for the flight, told us to wait, then ignored us while they helped many other passengers. Until I got rude, they would have left us standing there, and even then they were very curt and dismissive in telling us where to get boarding passes printed. We made it to the gate just as they were starting to board passengers. It was just rude customer service.

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Absolutely filthy flight and not equipped for a trans US

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

This flight was late and did not meet the connecting flight.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.
