Flight cancelled an hour before takeoff due to "unscheduled maintenance". New flight makes me have to wait for 5 hours in the airport, at a gate totally on the other side of where I'm at, requiring me to take a tram to get from the N terminal, to the C terminal. After waiting for 5 hours I'm informed my new flight is no longer at the gate I'm at, but instead is back in the N terminal where I was previously.

Flight cancelled an hour before takeoff due to "unscheduled maintenance". New flight makes me have to wait for 5 hours in the airport, at a gate totally on the other side of where I'm at, requiring me to take a tram to get from the N terminal, to the C terminal. After waiting for 5 hours I'm informed my new flight is no longer at the gate I'm at, but instead is back in the N terminal where I was previously.

Delayed an hour and sat without updates. Ended up an hour late to destination

The flight was decent again if there was a place that you could put crying children that would be great. Or maybe make a rule against allowing infants on the plane.

Everything was fine -- on time, clear, clean. I don't want to pay extra for in-flight wi-fi

The flight was delayed because the pilots had not arrived on their previous flight yet. The flight was 100% full so it was pretty crowded. I miss having the screens on the back of the seats. It would be great if the Alaska planes had the clip so you can put your phone or tablet on the back of the seat in front of you to not strain your neck. Everything else was very smooth.

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.
