Airline reviews
Pros: "The crew was very friendly. The seats were comfortable. But most of all, I felt safe on the flight."
Cons: "Nothing I can think of. Thank you for a peaceful flight."
Pros: "The crew was very friendly. The seats were comfortable. But most of all, I felt safe on the flight."
Cons: "Nothing I can think of. Thank you for a peaceful flight."
Pros: "Seat comfort. Seats are really roomy."
Cons: "The landing was impactful; we literally hit the ground. Landing could have been smoother. We sat between runways for 15 minutes. Not good."
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: "Great crew, smooth landing."
Cons: "The “Mediterranean tapas” meal is basically a tiny tiny school lunch, minus the comfort of PB&J. Want dried apricots? You get FOUR. All in all not too bad though. The entertainment/WiFi system is limiting- maybe REMIND us to bring headphones? And no WiFi unless you have T-Mobile? Tease."
Pros: "decent leg room and the headrest could bend to allow you to sleep upright."
Pros: "New and clean aircraft."
Cons: "Very few movies available. Huge delay to get off ground."
Pros: "Clean, newer plane on time with courteous professional staff. All went very well."
Cons: "Not a thing."
Cons: "If there was a less than one star that is what they deserve. SFO flight was late. They gave away my seat on my connection to Kalispell. They basically blamed me for being late and not being there on time. Two others from my flight were allowed to make the connection but told me that they gave my seat away because I was late. We all showed up at the same time from the late flight. I talked to 3 people including customer service and did not get a single “I’m Sorry”. Do they not communicate with each other when a flight is late and they have passengers for connections running late? They told me they don’t talk. The best they can do is put me standby for 9:30 flight and if I cannot get on that flight I have to wait until morning. My daughter is in a competition tomorrow morning and thanks to Alaska Airlines I’m going to miss it. I’m sitting here writing this review, paying for a dinner I should not be paying for and probably searching out a hotel room until morning when I can catch a flight. Unbelievable the lack of empathy."
Pros: "The crew was so darn efficient and the pilot was so funny over the speaker! Thank you Alaska for slaying this flight"
