Pros: "I was sitting by the windows and it felt a little cramped on the Q400."
Cons: "I would liked to have wifi."
Cons: "It was poor flight took off late and it arrived in Las Vegas late I miss my connection connecting flight the put on a different airlines got in late miss my ride and now I'm stranded at the airport"
Pros: "Bryan was my steward on flight 1402 from Seattle to Portland and he was so kind and helpful. Will fly again just because of him."
Pros: "The snack was a whole sandwich that was quite tasty and in my opinion far better than the two meals I was served on my US to Europe flight on Condor. The staff were very kind, accommodating and served us damp linens to wipe our hands with before eating, which I did not receive on the Condor flight."
Pros: "Air traffic control re-routed the flight which delayed our take off and extended our flight time. The captain was good about keeping us informed about the delay, and the new schedule. The delay wasn’t Alaska’s fault, and the crew made the best of a not ideal situation."
Cons: "Missed 2nd leg of flight due to 1st leg not taking off at correct time due to improper scheduling on Alaska’s part at SeaTac airport. Forced to take next flight the following day without any accommodation for my wife and 3 year old son. Was told by Alaska service agent to just sleep at the USO."
Pros: "Food was excellent service was good"
Cons: "Boarding was too slow we sat at gate for almost an hour for baggage to be loaded"
Pros: "Free movies"
Cons: "First time on Alaska air, on my departure got delayed for 8hrs, then that one we end up deplaning. On my arrival, the plane got delayed again. It’s not a good experience all and all"
Pros: "Staff were all fabulous and who doesn't love free drinks?"
Cons: "30$ per bag made us reconsider/repack everything, lug around heavy carry on (which we measured in their box), only to have to check it anyway as told to MANY "this size doesn't fit this particular plane." Ot was a pain to pick up in pouring rain & made some miss connecting flights."
Pros: "Always enjoy flying Alaska. Especially like that I can get a good coffee or a good beer on every flight."
Cons: "Nothing."
Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Pros: "When I asked for a seat change the crew was very accommodating"
Cons: "With covid in Seattle I was placed next to a restroom. I did not see any bathroom sanitation occurring during the flight, and no sanitizer available anywhere."
Pros: "Crew was awesome! Service was quick!"
Cons: "One flight the plane was quite warm and the air overhead was blowing warm air.. didn’t cool down until we were preparing to land and then it blew warm air out again.."

Pros: "Flight was good and crew were good. Nothing very outstanding but by no means a terrible flight."
Cons: "The in flight screens weren't working well."
Cons: "Delayed flight planning - would have been nice to delay the flight before boarding."
Cons: "Flight into Seattle delayed, flight out of Seattle to Minneapolis delayed flights out of Minneapolis to Bismarck delayed. Ran from gate F to gate c24 arrived at 10:23 p.m. Slight to the park at 10:25 p.m. and they closed the door on me as I was running up there. Ran across the entire terminal to get there and they would not let me on. Last Flight of the night to Bismarck. Missed my uncle's 90th birthday party. Would not give me food voucher. Delta gate agent told me she would lose her job if she did not close the doors 8 minutes prior. However the Minneapolis flight waited for 15 minutes for people to board that plane. How does that compute? Why would they not wait 3 minutes for me rather than pay the money to put me up in a hotel?"
Pros: "Direct flight"
Cons: "Online check in, we’re charged for everything, EVERYTHING. For that I’ll take a connection next time"
Pros: "They sat my family together and the crew was amazing."

Cons: "Business class for 4.5hrs overnight without flat seats!! Zero entertainment!"
Pros: "Great crew!"
Cons: "We paid for WiFi but it was not working on this flight."

I missed my work meeting from this."

Pros: "Nothing...I missed this flight due to negligence, miscommunication, and incompetence by the front desk agents."
Cons: "Everything"
Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"
Cons: "Service for people not able to sleep on the long haul"
Pros: "I watched a good movie."
Cons: "The plane seemed old. Food was pretty lousy. Hummus was dry, crackers were stale."
Cons: "proverbially poor United service, this time compounded by weather-related flight delay. when gate agents are nowhere to be found and all the information one gets is terse departure update via the app, one knows that flight should have booked on a different airline."
