Take Alaska Airlines - Clear was great to have at both airports, especially seattle where there was a large security line

SeaTac does not have a very good or equitable system for security lines. First class passengers don’t have a TSA precheck option, while there are only 2 TSA precheck lines on opposite sides of the terminal. Highly recommend getting TSA plus Clear, as the airport heavily favors this combination, with each section of the terminal having one of these options. I almost missed my flight because the only TSA precheck line was about 45 minutes long.

Tight interline connection at LAX - barely made the flight. Directions from AS arrival gate to separate AA commuter terminal for AS codeshare flight connecting to TUS would have been nice.

If you have kids, bring your own screens. We were counting on the inflight entertainment and it was a definite letdown. Also, TSA Pre-check is only available at station 2, but wait times are posted at each station so you can see if it’s worth the walk.

People were friendly. Flight was a little delayed. Maybe I missed the reason for it. Overall a nice experience.

I was surprised by everything. The cleanliness, the punctuality, the friendliness of the crew… and the Wi-Fi! Please keep up the good work.

See what I wrote in the previous section. This was a terrible experience. I would like refund.. I even paid an extra $70 for an aisle seat closer to the front to ensure that I got off early enough to catch the next flight. The fact that the plane did not wait, and even left eearlier, knowing that the first flight came in late, and was moved to a terminal three train stops away is appalling. My friend that flew JetBlue, their flight was delayed and came in later and the connecting flight WAITED for them. How is it that JetBlue could do that, and Alaska could not.

It was a bumpy flight but the crew was very attentive and made it a safe and enjoyable experience.

Delay of more than 3 hours I didnt recieve neither a voucher for food Attention disaster

I needed to board early and that was no problem. The snack was just ok. Alaska is an EXCELLENT airlines . . . luggage fast and easy.

SeaTac was a mess first class check-in not clearly identified Temporary signage needed since only one door into Alaska check-in area directed you to coach baggage check.

I was in the very last row, across from the restrooms. It was Okay--no odors--but impossible to move the seat back, and there are no upper usable luggage compartments that far back. Not a problem for me as I didn't need one, but for other passengers, it did create a problem. It was a comfortable flight.

This is a horrible experience. I purchased upgraded seats months ahead of time. Seat 6A specifically for my wife, and 7B for myself. On the day of travel, we were issued boarding passes that reflected the seats that we purchased. However, at the gate when checking on to the airplane, we were told that our seats have been changed to the very back of the row next to the restroom. I explained that I purchased the seats ahead of time. And that this was important to us, hence why we plan ahead.the agent apologized and said that CA was given to somebody else so their family could sit next to each other. Family, who evidently did not plan ahead. Nor did they pay extra for that seat. Subsequently, my seat was also changed. I was told this was because somebody was handicapped and knew that seat. I can understand boarding early if you’re handicapped, but what does 20 feet of distance matter at all. I watched. The agent apologized and said that CA was given to somebody else so their family could sit next to each other. Family, who evidently did not plan ahead. Nor did they pay extra for that seat. Subsequently, my seat was also changed. I was told this was because somebody was handicapped and knew that seat. I can understand boarding early if you’re handicapped, but what does 20 feet of distance matter at all. I watched the so-called handicapped couple haggle and Hagle and Hagle and eventually the agent came in. They were Indian couple and I can assure you they were not handicap. I can also assure you that they did not pay extra for that seat like I did. This is some of the worst performance, and as well as customer service I have ever experienced. This is absolutely Unacceptable. The agent said I can file a complaint and try to get a refund issued for the extra money for those seats. I simply said to the agent the same thing I will say to you. I don’t care about the extra money. I wanted the seat. I paid for the seat. I expect a full refund for both of those tickets at a minimum. I hope you feel this is not reflect Alaska Airlines. I hope you will make it right.

It would have been nice to have wi-fi, but I only care about the quality of the flight, which was excellent- smooth takeoff, smooth landing, and very little turbulence. I don't care about food, entertainment, etc.

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

They canceled flight. Hard to believe there was even a plane incoming for us to get on

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

Most horrible airlines. Please avoid it. It's ok to spend $50 extra for delta, united or Alaska

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.
