Alaska drastically changed our flight from a direct flight to a flight with connection and a long layover. So we canceled the Alaska flight and we learned a valuable lesson that we will never book through kayak again because the third party travel agent tried to withhold our money.

Alaska drastically changed our flight from a direct flight to a flight with connection and a long layover. So we canceled the Alaska flight and we learned a valuable lesson that we will never book through kayak again because the third party travel agent tried to withhold our money.

It was a super old plane so the first class experience was just not luxurious

I’m not sure there is anything that can be improved, even the cost was fantastic.

We were singled out, greeted and helped with check-in at the busy airport. They offered to take our bags there and gave no fuss when we said they were carry-on. With United just last week I had to put up a fight just to get onto the flight with my one authorized carry-on.

The flight was jumping between being delayed and closer to schedule about 5 times. Alaska air website showed incorrect times while google had latest info. This panic was horrible to deal with.

The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight delay was inconvenient and exhausting getting in at 1 am. However the crew and lounge was very comfortable.

I had never flown Alaska before. Years ago I flew constantly. Flying these days is not a glamorous experience. It’s not that easy to get inexpensive direct flights either. Not glamorous but reasonably priced and comfortable. I appreciated the inflight WiFi (for messaging only but that’s ok, I like to read on flights). I didn’t check the inflight entertainment, see above. I was lucky on the AUS => SFO flight—they needed volunteers to check bags at the gate. That bumped me up a level in status so they let me move to an empty exit row. The return flight I was assigned a seat in one. Very nice. As pleasant a trip as possible these days.

It would be nice if you had free internet. Text messaging is appreciated.

Plane hit turbulence diverted to Houston. We'll probably get in after 3am
