First time on Alaska. Multi-million miler on United. Alaska is much nicer.

We were stuck on the tarmac for an hour when the engine would not start but ended up arriving on time. I was provided a complimentary drink which was a delightful surprise. Seats were comfy too.

The flight attendants were very nice and helpful! Also, the pilots managed to land the plane safely, despite major turbulence caused by high winds. They deserve special kudos.

I loved how the pilot came out and introduced himself. I loved that he told us which states we were flying over. Great interaction with military that was traveling.
