I've never experienced it as an Elite Plus. However my partner, flying economy in Lufthansa from ARN-MUC was aproached by an FA who thanked him for flying with them and asked if she could offer him something to drink. It was a very nice touch but since my partner was traveling with his group seated around him, he had to decline As a comparison, I flew first time as a One World Emerald in Cathay Pacific economy class from Singapore to Hong Kong last January and I was approached by an FA who welcomed me and gave me a bottle of Evian water. I think One World takes good care of their elites better
