Cons: "N/A"

Pros: "Good timing"
Cons: "All went well"

Pros: "Love that they have free movie choices and free earphones. Also, loved the menu for drinks and food!"

Pros: "Short lines, efficient service, most of all kind staff all the way from the counter attendants to the pilots."

Cons: "We were delayed for 40 min and had a last minute gate change"

Pros: "Seats are comfortable and feel roomier than most, boarding was easy, flight was turbulant but still comfortable and even arrived early, fantastic crew, never have an issue."
Cons: "The following are not complaints just my review of the topics given: I did not purchase any food on my Alaska flights because there were no plant based (vegan) options. I was unable to use the in-flight entertainment that was advertised (many times) for unknown reasons."

Cons: "Flight was delayed"

Pros: "On time"

Cons: "Great crew! Smooth flight. Need more hot options for food"

Pros: "Nothing"
Cons: "Missed connecting flight"

Pros: "Even though plane was full, comfortable"
Cons: "needed appropriate food for red eye Miss warm cookies and milk"

Pros: "All good with Alaska and Virgin America"

Cons: "No free food was offered. Movies were not free."

Pros: "Great service and perks in first class."
Cons: "Entertainment tablets did not include some of the titles available with gogo wifi service. Gogo entertainment required downloading an app without play store that is generally not secure. Food was good but salad should be fresher or replaced with some winter option."

Pros: "timeliness, courteous, comfortable, charging outlets at every seat."
Cons: "weak movie selection"

Pros: "Pleasant attendants"
Cons: "All good"

Pros: "Boarding was efficient, seat was comfortable. I appreciate that food and drinks were offered often."
Cons: "One particular flight attendant purposely ignored me when I tried to ask for cream and sugar for my coffee which she did not offer when handing out drinks. Then she looked right at me twice as I tried to give her my garbage which she was collecting, but she ignored me again and left me holding my garbage until a different flight attendant came much later and took it without incident. It made me wonder if it was because I looked Asian- she was helpful and polite to the white women next to me. I was polite and was not being difficult in any way. I'm half white, but was often treated like this in Illinois when I was growing up. She should have been professional and if she had I would have rated the trip as excellent."

Pros: "Great service. Offered me a seat switch on full flt! Internet was tough and not working well but gogo almost always is. That was minor. Easy nice flight."

Pros: "Appreciated the outlet at each seat to easily charge phone/ tablet. Often not enough time seated in airport to allow much charging. Pilot got us to destination almost 30 minutes early, so that was also nice."
Cons: "I absolutely hate having to pay for even the 1st checked bag. 1st bag should fly free; I have to remember to take Southwest whenever possible in the future to avoid that added cost! The baggage fee added $100 to our roundtrip cost, thus making it MORE expensive than my usual others."

Pros: "nice helpful employees. On time service."
Cons: "nothing"

Pros: "Seats are a little larger n more legroom for my 6'2" big man of a husband"

Pros: "Your typical airlines for check-in, baggage etc but I was pleasantly surprised when our seat assignments were together for the return trip w/out having to select them. Baggage was extremely fast on the outbound flight but took a few minutes on the return flight."
Cons: "Again, as with most airlines, the seating room leaves a little bit to be desired but the leg room was adequate for a 6'4" man."

Pros: "I've always had a good experience with Alaska Air."

Pros: "Plenty of overhead bin space; no excessive announcements; ultra clean cabin; flight deck explained the lengthy ORD taxi time to the arrival gate"
Cons: "FA's appeared to be rushed during boarding. I was asked to put up my tray table, and I spilled all of my French fries on the floor as the flight attendant watched. I had to leave the mess all over the floor. My seat neighbor offered to help clean the mess. I cleaned it up on my own with a safety information card as a scoop and dumped the mess into a puke bag. The flight attendant should have offered a trash bag as there was plenty of time before takeoff. I flew for your airline as a flight attendant for almost four years, and I know AS flight attendants are among the best."

Pros: "I liked the choices of food and the movies!"
Cons: "I thought it took too long to get the laptops out. I didn't finish my movie."

Cons: "Seating felt a little more cramped than usual."

Cons: "Wondering why a very intoxicated man was asked to sit next to me. He had two deep cuts in his fingers, couldn't focus on sitting down, awful hygiene, was sold two vodka cocktails, and he hit his eye on the straw because he fell to sleep then woke up to drink more. I felt very uncomfortable throughout the entire flight and would like to speak with someone from Alaska Airlines."

Pros: "Both my flights were great, and especially my outgoing flight from Chicago, the attendants at the gate were amazing. I don't think I've ever met more helpful, nice attendants--nothing seemed rushed, and they were helpful and happy. Similarly, the attendants on the flight were really nice and cheerful. Flights left on time, and I got in early on my first flight. I've flown a lot in the last year, but this was one of my better experiences with an airline. Check-in was really easy too."

Pros: "I like a lot the treatment"

Cons: "I requested an aisle seat because I have broad shoulders and a knee that hurts if I can't extend it. EVERY TIME a particular stewardess would pass, she'd SLAM into my shoulder, with no care or apology. This was very hard to enjoy a drink, or sleep, or do anything on the flight."

Cons: "See above."

Pros: "Wonderful seat and attendants."

Pros: "Straightforward. Love that Starbucks coffee is offered! Also love that you can charge devices. The inflight entertainment option works for me; I usually come prepared but I was happy to pay to watch a movie, although the cost seemed unnecessarily high."
Cons: "There was quite a bit of wait at boarding time while standby seating was sorted out. I wasn't sure why ticketed customers could not board on schedule; instead, everyone was standing around at the scheduled board time while names were announced, etc."

Pros: "I have become a major fan of Alaska Airlines. Check In is so easy, the attendants are friendly, the food is worth purchasing (although a bit too spicy for me), the choices of flight times is impressive. I have flown with Alaska three times in the past year and every flight was booked solid. Must be lots of others who feel the same way I do."

Pros: "Having an exit row"

Pros: "On Time, polite staff."
Cons: "Tablets for entertainment for additional cost. THe most significant point is that nobody can hear the announcements when listening to their tablets."

Pros: "Seats, beer selection, very friendly staff I will be flying again if I get the chance and I never say that anymore about other carriers."

Pros: "On time"
Cons: "Nathing"

Pros: "Pilot information/anoucements."

Pros: "Not much at all really. Getting off the plane was nice."
Cons: "I didn't like being at the airport all day to be within 15 minutes of boarding and all of the sudden the flight was delayed 5+ hours. I could have gotten a hotel for the night again. Then after we get on the flight we have to sit in Seattle for an hour and a half because they had to fuel the plane up and switch crews. Not impressed."

Pros: "The flight was fine. Typical of any other airline company."
Cons: "They managed to lose my box of fish on a Direct flight from Anchorage to Chicago. I might be more understanding if I had connecting flights. Unacceptable..."

Cons: "For such a long flight at night we weren't offered a pillow to use or blanket and the seats are so small and cramped it was hard to get comfortable.one snack was offered the whole flight and the prices were too expensive to order."

Pros: "Everything was on time considering the heavy Holidays travels."

Pros: "individual headphones and screens for entertainment"
Cons: "better advise about duty free items"

Pros: "Landed safely."

Cons: "Delayed a total of four hous!"

Pros: "NOTHING"

Cons: "Think it is ridiculous that I had to pay so much to select a seat ahead of time, and it was just a regular seat. I can understand for extra legroom or exit row, but for a regular seat, that is ridiculous. Then there was a fee to change priority boarding, so I could ensure I was able to have my carry-on with me, instead of risk having it go underneath. Unable to use the entertainment, as I was unaware had to use my own device, which I had not set up in advance."

Cons: "The boarding process. Again, not the staff's fault."
