It was fine since it ensure we went to our destination in time.

I bought the cheapest ticket. No meal, no checked luggage so I didn't expect much and was surprised by how good the flight and service was. Alaska is now my favorite airline.

No entertainment, food was cookies & juice,water, soda or coffee.

My baggage was in another flight, anit was delayed for one hour.

The maintenance delay was seemingly handled very poorly... Little to no information was provided to the passengers sitting on board for an extended period of time. On a brighter note, at least the cabin crew (flight attendants) did the best they could. They seemingly were provided very little information with regards to the delay. Unless absolutely beyond my control, I can’t imagine buying a ticket on Alaska airlines again, based on this and a previous experience my wife recently had, along with complaints overheard from other passengers.

The only issue was in the wheelchair waiting area before we got on the plane. They seemed very disorganized. Everyone we encountered after that was great! We loved Cassandra at check-in. She was awesome. The flight attendants were wonderful too! The lady helping with the waiting wheelchair when we got off the plane was awesome too!

Expect to get miles for us having to miss our first planned flight due to them waiting on passengers that decided to be late to the airport.

Up on arrival, due to twisted ankle, I wasn’t able to walk. Requested for a wheelchair. They immediately asked for it. After 10 minutes wait a young man named Carlos picked me up at the gate, got my baggage and took me to the pick up area. It was a great service. Thanks Alaska Air line

Once I was in my seat, it wasn't as comfortable. It was very tight (width wise).

Just a little delay in our takeoff but all was well and pleasant.
