Cons: "Delayed boarding but received notification from Kayak was good."

Cons: "Seat cushions are too thin."

Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Pros: "The flight attendants were friendly and professional and took time for a little personal conversation."

Pros: "Comfortable seats with nice details; power ports; drinks and snacks."
Cons: "Boarding in Seattle was ridiculous. Security took a massive amount of time, and we barely arrived in time for th flight despite arriving hours early. The attendants at the gate were a bit rude and begrudgingly accommodating."

Cons: "Employees who just don't care"

Pros: "Management as well as staff nice...First trip with Alaska and made my trip nice .. Got a good deal price too."
Cons: "Nothing."

Pros: "Plane very warm, not comfortable. Only one pass for beverage service."
Cons: "Very warm air vents did not work."

Pros: "- Crew was friendly as usual"
Cons: "- The plane was a bit older, so the seats were not as comfortable as most Alaska flights"

Cons: "boarding was late due to repairs on the plane"

Cons: "i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight."

Pros: "It was a short flight. The overhead bins weren't overloaded."
Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."

Cons: "Two out of three USB ports would not hold cable on my premium seat row. Would not recommend if something as simple as USB port inoperable is not handled by cabin service or maintenance. We paid additional fees for this seating and couldn’t keep device charged. Very disappointing"

Pros: "I didn't have to set next to a 500 pound cow."
Cons: "Your beer and wine is sooooooo expensive."

Cons: "Food and wine way over priced."

Pros: "Cimfortable seats on a brand new jet, with excellent food and wine, and great service!"
Cons: "Flight was too short"

Pros: "Brand new airplane with comfortable Recaro seats. Great food and wine. Excellent service."
Cons: "Nothing. Alaska Airlines provides the best service available."

Cons: "45 minute delay due to fog"

Pros: "I'm a big fan of Alaska Airlines and their partner Horizon Airlines. I travelled from Edmonton to Denver via Seattle last night. All the staff if pleasant and treats you as a valued customer."

Pros: "Boarding was a breeze, crew communicated well, seats were comfortable, plane wasn't too hot or too cold"
Cons: "Had a problem with checking my baggage in anchorage which led to $300 being held from my account for 5 days. They refunded my baggage fee though"

Pros: "Everything but…"
Cons: "You lost my backpack with $2000 worth of hiking gear that I will not be able to replace before I am supposed to leave on a trip. How could this happen?! This bag was full of all the material possessions in the world that matter to me."

Pros: "Seat was comfortable and in-flight service was very good."
Cons: "Gogoinflight didn't work for at least the first 30 minutes of flight. I upgraded to first class, but there was no service until we were above 10,000 feet. I don't know if this was a one-time thing, or if other airlines are just better at accommodating first class."

Pros: "Friendly staff. Made up time after a mandatory tire change."
Cons: "Other passengers not listening to the staff."

Cons: "No legroom unless you pay more for it."

Cons: "Gate 11c."

Cons: "Nada"

Cons: "not able to know my seat till a day before flight ."

Pros: "Almost everything. First time flying with Alaska Airlines thought the food would be better o thought the food would be better on such a long flight but it was enough to snack on until I got to Seattle great experience in between flights was able to get an earlier flight to Denver"
Cons: "Wish there was a little bit more offered for food but overall a fantastic experience mahalo"

Cons: "Service was amazing"

Pros: "Great service and very organized."

Pros: "price"
Cons: "delayed"

Pros: "Early flight, and short. I think I slept through it. Woke up sore, but eh I'm not surprised by that. I'm a giant and no one woke me up for anything so I was satisfied."

Pros: "The crew and captain were amazing and very apologetic!"
Cons: "I paid an extra $300 for preferred seating because I wanted the extra legroom to sleep. I'm over 6 feet so coach is very uncomfortable. My girlfriend and I got in our seats and 10 minutes later, a crew member walked back and asked us to get off the flight. We got off the flight and were met by police officer. Low and behold, the woman sitting next to us said that she believed we were intoxicated and feared for her safety. I am a police officer and my girlfriend is a nanny/preschool teacher. Not very threatening. The officer on the ground looked us over and asked us a few questions and determined we were not intoxicated and we were no threat to the other passengers. The airline asked us to get back on the flight and we would be sitting in coach because the woman adult children were now sitting in our seats. I told them to book us on another flight with the same seats that I PAID for or put us back in OUR seats on that same flight we just got kicked off of. We were escorted back onto the flight and the crew asked the woman's children to go back to their seats so we could have our seats back. They then asked us not to speak to the woman sitting next to us (which we never did to begin with!!!) and then told us we could have free food and drinks. The whole experience was insanely embarrassed and I can't believe that woman sitting next to us can get away with what she did. I am absolutely livid that they would ask us to get off the flight and then give our seats to the woman's ADULT children without vetting the situation and making the easy determination that we were NOT intoxicated. So embarrassing!!"

Pros: "Glad I discovered Alaska Airlines!"

Pros: "It got cancelled due to 3 inch of snow. And I missed work in Denver because of it. Very inconvenient"
Cons: "I would like to not have it cancel"

Pros: "Offering price"
Cons: "Real price. Ridiculous after carry-on and other fees"

Pros: "Attendants were very friendly and flight arrived early."
Cons: "We were stuck on the runway for 30 minutes."

Pros: "Newer aircraft"
Cons: "1-1/2 hours delay, no reason was given."

Pros: "Ditto statements above"
Cons: "Ditto statements above"

Pros: "good"

Pros: "Their staff was awesome as usual no issues with the flight ."
Cons: "So many bags that were suppose to go under the seat infront of you that weren't. So that those of us that boarded last had to wait while stewarts removed small carry ons. So that our one carry on that fit in the box but not under the seat could be stowed. It would be nice if the smalls bags that are to be stowed under the seat were. The family next to me had 9 bags in the over head. There were two adults and two children 3 and 4."

Cons: "Nicest people ever."

Pros: "Alaska airlines is absolutely wonderful. Friendly, happy and simple..."

Pros: "Roomy seats and plenty of legroom"
Cons: "The whole experience of making a connection in SEA detracts from the travel experience. There is little room for passengers to sit while waiting for their Alaska flight. It causes masses of people in the walkways, and makes it hard to walk through, or get out of the way for others. It may not be the airline's fault, but as I said, it detracted. I don't remember SEA being that overcrowded on previous trips. Our incoming flight was delayed due to weather. Again, not the airline's fault, but we were told we'd be able to make up the time and be on time in DEN. We were still late."

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Spacing people out until this covid is over"

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes...
