Alaska Airlines is my absolute favorite, but they really slipped up here. Frequent flyer or not, you can't brush this kind of behavior off as "oh he's just a dirty man who flies with us a lot, just ignore him", while then continuing to just give him more alcohol. Allegedly even the flight attendants came by and apparently knowing these reoccurring problems with him, asked "So, are you behaving today?" with a smirk. Any economy class passenger would've been immediately thrown off the plane.
Disturbing and I would hope the fact that just because someone is rich doesn't supersede the comfort and safety around myself and Elsa when flying their airline also, as it's the main airline we use.
