I’m biased. I work at the airport and within these systems so I know how to be effective. On top of that part though everyone was friendly and helpful. Both legs of my trip were on time. My baggage was handled with care. Alaska’s part of my experience was top notch.

I’m biased. I work at the airport and within these systems so I know how to be effective. On top of that part though everyone was friendly and helpful. Both legs of my trip were on time. My baggage was handled with care. Alaska’s part of my experience was top notch.

Hello, Our flight arrived late, and the flight we were to connect to the departure time was moved up. At first our flight was scheduled to arrive at 10:40, but it arrived at 10:56. Our connecting flight was scheduled to leave at 11:25, and it was moved to 11:20. Also the terminal was moved from N to S. N would have been in the same terminal as the one we arrived in-- to get to S we had to take 3 trains to get to. And when we arrived at the gate, around 11:15, they said the gate was closed and would not open it. We had come from a funeral in Boston, and the person that helped us get new tickets said, "did you come from a girsl trip?" No, we did not. We were coming from a funeral. This experience was not what we expected/wanted. My friend, because she had to run to S, got a migraine and turned pale. In addition, I paid an extra $70 for an aisle seat that was more upfront, to make sure I can get off the plane faster and make the connecting flight. The fact that the plane not only did not wait, but left earlier, is absolutely unacceptable. This was a terrible experience, and I hope that I can be refunded for this horrible experience.

A gentleman at the desk for my boarding from Seattle to Anchorage randomly selected me and told me they would need to check my carry-on despite having multiple lithium-ion batteries all of which were in communication devices essential for time in Alaska. There was ample overhead compartment space and I was lucky non of my equipment was damaged due to his unnecessary use of power. A quick check with the flight crew would have likely resulted in an answer that ample space remained allowing me to keep my personal and important items near by. I did lose WiFi twice and that detracted from my entertainment which I do not commonly use.

The TSA pre check with photo linked to Alaskan airlines was extremely fast & convenient.

Flight was cancelled which destroyed the rest of our journey.

no lounge in Orlando while waiting for flight no inflight entertainment screens in first class

Thanks for all you do to keep us safe and on time!

My very first, first class flight! Loved the comfortable seats, foot rest and beverages. Did not have food due to short flight. Crew was very friendly!

This was my first time flying first class. I was really disappointed with the food option and lack of entertainment. I wasn’t given an option of what to eat. The breakfast was less than desirable. It was a bowl of some type of granola cereal, dried fruit, almond butter and 3 biscuits that we pretty much tasteless. There was so much fiber in that meal I was afraid I would poop myself in the flight. There was absolutely ZERO entertainment available. No tv screen to watch a movie or listen to music. No charging port for my phone. I recently flew Delta Airlines Comfort class and I had a tv screen with numerous options of music to listen to and movies to watch. Also I had a charging port for my phone. I expected more quality from first class. Please understand I am not some prima donna that feels entitled. But the price I paid for first class wasn’t worth what I experienced.

I've been loyal to Alaska Airlines for nearly 25 years and before the merger I had much better benefits. However, since the merger with Hawaiian Air, you've bumped me from group A to B or C and I now get poor selection of seats in the back of the plane.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

The rear seat on the second leg should be illegal. There’s no way you should make somebody sit that close to the washroom. Very awkward.

Terrific in every way. On time, professional staff, multiple movie options to select, great food and drink.

My bags were misplaced!!! Im in a foreign country with no bags

The entertainment options on the seat back video boards were nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

Dinner was good, but the breakfast served in the morning was horrible.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

Got home at 3am after deboarding the plane. No compensation offered by American

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

The seats need better cushioning for a nearly 5-hour flight, it was a bit uncomfortable. I'm glad American has free wi-fi but there were was a bout 30 minutes in the middle of the flight when there was no connection which was frustrating.

My original flight got delayed day of so I had to rebook it from one layover to two layovers. The flight also left earlier which was a slight inconvenience but manageable. Then my first connection flight got delayed 3 separate times for a total of 2 hours delayed, causing me to miss my second connection flight back to Santa Barbara. Now, because of this missed flight, I am missing my college classes that I pay for.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.
