Jeez, y'all. It's not as if ShamRockSteady is seeking advice in re: thank you notes to billionaires for paying their fair share of taxes -- s/he just wants some help guesstimating how many chocolates/trinkets/Birkin bags to buy. People have been bringing small gifts to flight attendants since forever and a day. And that being said, OP, I have no idea, so I'm also of zero help to you.
