Back in the olden days (2015-ish?) KLM was having a really, really cheap business fare sale JFK-AMS; I snagged it with Delta miles (if I recall correctly) - and flew there and back in their 747 in the upper deck (just to take the flight; didn't have anything to do in AMS). It was really quite nice; it was the first and apparently last time I've taken the 744. I'm really glad I was able to do it.
