I like the leg room. Coffee was so bad that it gave me stomach pain.

Read more about Alaska Airlines

I like the leg room. Coffee was so bad that it gave me stomach pain.

Cons: "Better business class seating, better food and in seat entertainment as it isn’t enjoyable watching movies on an iPhone."
Pros: "Alaska airlines staff from checking in to flying set the bar in service standards. I have never been disappointed with their professionalism and will continue to use their services exclusively when I can."
Cons: "Nothing."
Pros: "The flight attendant was so amazing and observant that she noticed myself and classmates all wearing our alma maters sweatshirt and gave us the loveliest a shout out!! We were headed for our college reunion and had unintentionally been on the same flight. That was so much fun!!"
Cons: "Free headphones"
Pros: "Smooth flight, easy on and off."
Cons: "Staff could have paid a little more attention to what the were doing. Asked 3 times for apple juice and got orange juice. By time I realized what he had given me, he was gone ☹️"
Pros: "Even though I was in Group C, I was one of the first to board (Groups A, B, and C were called to board all at once). Since the gate agent said the flight was full and there would be limited space for carry-on bags, being one of the first on the plane was nice. The leg room (I'm 6'2") was good."
Cons: "The crew only did one pass through the cabin with soft drinks. Perhaps because it was a red-eye? Anyway, on a nearly 5 hour flight, I would have liked more than one small cup of refreshment."
Pros: "Kind crew and comfy seats."
Cons: "The seats were too compact, and the water tasted funny. Also IAD is not well equipped for snow."
Pros: "The crew was very good, caring and concerned."
Cons: "I don't think anything, this was another amazing flight with Alasks"
Cons: "More plentiful food selections? Everything served had dairy which I can’t do."
Pros: "Lots of entertainment options"
Cons: "Need a snack on a six-hour flight. Also, didn't receive drink service until a couple of hours in and was only served about 1/4 cup worth of soda. Disappointing"
Pros: "Jet blue flights seem generally good. Like the WiFi access to be Able to use flight time efficiently."
Pros: "Crew was amazing. It was the pilot’s last flight before retirement, so it was fun celebrating with him and the crew. Seats were comfortable."
Pros: "Comfortable seating with lots of legroom; clean; ease of boarding and de-boarding; on time; nice variety of entertainment available ; everything was timely!"
Cons: "Some of the channels on the direct tv were not available throughout the whole flight; one flight attendant was not very friendly (she wasn’t rude either)."
Pros: "Personalized service, even in economy. Friendly faces, who seemed intent on providing the best customer service."
Cons: "Not much."
Pros: "Flight was on time, extra room seats were very comfortable."
Pros: "Crew was super nice and helpful"
Cons: "Agent at gate was hard to understand when making announcements - not due to accent or anything like that - he just spoke too quickly and directly into mic. He kept saying something about our flight moving to a different gate but it didn’t- very confusing"
Pros: "The crew was very good. The seat was okay."
Cons: "There was some sort of breakdown and the flight was delayed about 40 min"
Pros: "Not applicable since flight changed to direct flight to FLL"
Pros: "only two flights a day both of them got delay for more than 5 hours unacceptable"
Cons: "Delayed 1.5 hours, in spite of good weather at both airports."
Cons: "The crew was overly aggressive with mask policy enforcement. They patrolled the aisles and routine pointed at passengers directing them in a hostile manner to keep their masks on their faces, even when they were trying to eat or drink. They also threatened customers by stating it was a federal law several times. It was very uncomfortable to say the least. I will not fly delta again by choice."
Pros: "Crew was friendly and engaging"
Cons: "I wiped down my seat area to clean it. It would be nice to know what Delta is doing as well."
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Pros: "No comments"
Cons: "Cleaners had not done a great job. There were paper napkins left over in the seat pocket from earlier flight."
Pros: "The crew were average seats were comfortable."
Cons: "Being on time... I missed my connection to Eugene. They boarded late because the plane came in late but then fiddling around with paper work for 20 minutes. We were then one hour late and they unloaded on the ground and bussed us to the terminal making us even more late. Also $40 added at check in"
Pros: "Nothing"
Cons: "I was not allowed to board the flight. I arrived 30 minutes before departures and they refused to print my ticket. The lady claimed it was an airline policy to stop printing tickets 45 minutes before the flight leaves but on my original departure from Dallas I arrived 30 minutes early and waited in line until about 10 minutes before departure and they still printed my ticket. if its policy why was I able to do it the first time with no issue? i had to buy a whole new ticket with a new airline. I want a refund."
