Airline reviews

Pros: "easy to travel. Thats it."
Cons: "better management of the lines and clearer postings of the lines to board."

Pros: "They were nice and calm workers."
Cons: "I asked to check my bag while at the gate, and I was told yes just give me one second. They proceeded to call groups to enter the plane. I wasn’t helped. They forgot about me, then I went up 10 minutes before departure to board, and they told me I was late. It was a mess with overbooking too."

Pros: "Nothing"
Cons: "The flight was delayed so long, I missed my wedding day and had to rent a car and drive Shane was horrible"

Pros: "Flight arrived early Not full flight, more comfortable that way Boarding moved quickly, adequate overhead space Plane exit moved quickly"
Cons: "Flight attendant was rude as I switched into an empty seat following her count. Called out my move on front of other passengers with negative tone, but did not make me move, so OK overall. Without sale of open seat, the only way for Alaska to capitalize on that seat is to allow someone else to have a more positive flight experience with more personal space, so honestly she shouldn't have been rude. Tomato juice was hot from being outside, normally cool even without ice. Snack was fine, but minimal and snack boxes not available on short flight, so less stars for that. Entertainment nonexistent - film/tv access not available in flight without something in mobile device that was not explained, no plugs for charging."

I had my mobile boarding pass on my iPhone, and got to my departure gate. When it got close to boarding time, my email boarding pass disappeared!
