What do you think is the nicest small gestures that you can have onboard or on the ground by the FA/ground personnel that makes you feel appreciated? Or maybe feeling welcomed?

A small thank you note perhaps? A great smile as you are greeted onboard? Captains giving you business cards?

I've always found it very pleasant to be greeted with a 'enjoy your flight' by the ground staff, followed by a nice smile by FAs onboard as I entered the aircraft.

It's the little things that makes flying worth doing sort of things..
