My first leg from Beijing to Narita was a good experience and then on to Honolulu was among my best flight experiences ever! My second leg was a five-hour flight at night so I knew the crew would have some downtime as most passengers would be asleep. During the two-hour layover at Narita, I purchased a box of Chocolates for the flight attendants to share and gave it to them when boarding. They at first thought I wanted them to store the bag for me and I said no, it was for them to share with each other. Now I often do this because I am usually traveling as a backpacker and I am not especially well dressed after weeks/months on the road, on this occasion it was jeans and a Great Wall tourist tee-shirt. Foremost I like to do it because I know how hard they work and I want to express my gratitude for their efforts, that it also removes me from the category of just another person in cattle class in their eyes is a nice bonus. I am not sure if bringing a gift hit a Japanese cultural button but the reaction was like nothing I had ever experienced before. At different points of the flight, each attendant stopped by my seat to personally thank me and chat a bit, asking if I was a pilot or at least an airline employee. I literally could not pay for a drink, the Champagne flowed all through the night! Even when I insisted I had not done it for any kind of reward and would like to pay after the second one their response to this was to give me a diecast B777 in JAL livery, and more Champagne! When you fly your three biggest tools are, don't be a jerk, show appreciation and empathy to the cabin crew, express your gratitude before that moment at the door when deplaning!
