On PanAm from Rio to Miami on Christmas eve in the mid-80's, there was very, very light loading. The crew dressed up in Christmas elf costumes, sang slightly-off colored christmas carols, passed out gag presents, with the refreshments of a festive theme. No one slept. By the time we arrived, everyone was very "happy" (save the poor pilots) and the ground crew and customs/immigration people didn't know what to think.
