The staff is so nice and why not bring some presents. It's not for expecting any better treatment it's just humanity culture exchange . And while we have holdiay they are working. I also bring chocolates for cabin crews because I know they love snacking during their private times in the cabin kitchen
Tea and nuts is good idea. We ll travel from the Nordics (Finland ) this time. Might bring some salmiac or liquorice. And tea to flush down the flavour
