Airline reviews

1. Denial of Basic Needs (SEA): Upon arrival in Seattle, the wheelchair attendant refused my urgent request to use the restroom, insisting on scanning documents first. She eventually took me to a restroom but then abandoned me and my autistic son at an unstaffed, deserted gate for over four hours. When I called the accommodation line for help, I was told to "get someone's attention," which was impossible. My son, traumatized by the prospect of me yelling for help, was forced to wander the terminal to find assistance. 2. Revocation of Accommodations & Threats: At the gate, an agent stated I had no accommodations on file, despite my previous leg having them. When I showed the app (where my bulkhead seat was erased and replaced with Row 14), he denied the evidence. When I attempted to advocate for my immobilized leg, he threatened to "yank me from the flight" if I said one more word. He coerced me into agreeing that I was "asking for accommodations for the first time" before he would allow assistance, effectively forcing me to falsify the situation under duress. I complied only out of fear of being stranded in a strange city. 3. On-Board Negligence and Injury: Because my bulkhead seat was revoked, I was forced into Row 14. With my leg immobilized and unable to bend, it extended into the aisle. During boarding and the flight: 16 different passengers tripped over my injured leg. 6 rolled luggage bags were pulled over my injured leg. The Flight Attendant (FA) was one of the people who tripped and drove luggage over me. I reported the issue to the FA after 10 trips and 3 luggage impacts. He ignored me. He only addressed me later to ask me to move my immobilized leg for beverage service. I informed him again: "16 people have tripped, 6 luggage runovers, I cannot bend it." He provided no medical aid and no incident report. 4. Resolution and Trauma: Eventually, a different employee noticed my distress and my original paper boarding pass showing the correct bulkhead assignment. He asked me to move up. I broke down in tears, terrified that moving would cause the gate agent to remove me from the plane as threatened. We were eventually moved to the bulkhead, but the damage was done. My autistic son was traumatized by watching his mother be trampled and threatened. 5. Post-Flight: I called to report these injuries, but was disconnected after a 45-minute hold. I require a formal record of this injury and these violations.

The food selections were not good, and entertainment was non existent.

We flew economy, it was what I expected. The seats are too upright for me

I would like if it had happened already. I'm still waiting for it.

Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

The flight was fine, but the Kayak app is terrible. I could not input my flight. I couldn’t use it for anything and it would not even let me try to add a seat once you purchased the ticket you might as well. Delete the Kayak app as far as I’m concerned. I’m done with kayak. Com

Food and entertainment not applicable - standard drinks and cinnamon cookies; crew did not do a song and dance for us so no entertainment. I like the slightly better leg room than American Airlines - at least it felt that way. Flight crew and atmosphere seemed more welcoming than American, too.

this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.
