Really interesting to see the vast differences in Premium Class beverage offerings between them all.
AA on LAX-JFK, as you know, was open bar the whole flight in Business (with refills proactively offered). Also for wine they had multiple normal sized bottles of both red and white....FA even brought both whites over to me so I could see and choose. They even left the bottles out on the galley counter so it would be easy to get another plastic cup of wine on your way back from the bathroom (poured by an FA of course).
