Transition Layer's comments show why actual experience at this type of flying and consideration of all the facts is important before making comments as to what is possible and what is not. 36 hour slips in Europe are possible if the
airline schedule permits but often that's outside of the scope of the crew.
Personally I reckon that we can make some savings on some European sectors (and have suggested such to AIPA) but that just takes a nine day FRA trip down to eight days anyway!
