Outbound flight on KLM economy, the attendant always addressed me by my name and (secretly, hidden from other pax) brought me a delft house when I asked for one.

Return flight on AF economy, both myself and my partner (who is gold) were auto-upgraded at check-in to premium economy.
3 attendants greeted me personally before the take-off. One of them guessed my country of origin based on my surname, and spoke to me in my native language, which is not a spoken language at either the origin or destination. It was a pleasant surprise.

The pursur checked on me again prior to landing.
