Just came to think once reading other thread that there was an elderly couple onboard AY few weeks ago that I remember captain announced in three languages they had 50yrs anniversary (kultahäät) and all pax clapclapped.
They were served a fullsize domppabottle or I was not sure seeing which. I wonder if that was AY offering or did they pre-order it for tge flight?

(would be very FT to get to platinum anniversary, thats 80yrs!!)
