My only complaint is lack of WiFi on board. I believe they mentioned an issue with it, but my phone wouldn’t connect.

I really like the check in process. I wish the plane would board first class, then back to front. I kept getting hit by people’s bags as they walked by and when people had a backpack on trying to get luggage into the overhead compartment. Maybe a flight attendant helping people that are trying to get settled

My delta flight seat had more room and way better entertainment than my Alaskan flight. In my opinion Alaska should take notes from delta in every aspect of the commercial passenger flight industry.
