On a TATL flight I just completed on Delta two PAX brought with them a bag of fancy chocolates that they gave to the FAs. One of the PAX was using crutches because of a knee problem and did ask for ice to refill his ice bag. What surprised me was how friendly the FAs acted after getting the chocolates and they kept coming by and asking how the PAX were doing, did they need anything, and in a sort of attempt at secrecy gave them an amenity kit from the business elite class (they and I were in coach). As I usually fly CO, this was a rare Delta flight that I took because I didn't have to change planes, nonstop to Venice, and otherwise I found I like CO better, so I am wondering if I should start bringing chocolates to the FAs, particularly on TATL and TPAC flights ...
