Funny we actually have the ANA F booked for the next lunar new year (FRA-HND ANA F and then SQ C HND-SIN-HAN). Should be a very nice trip, 12 hours in tokyo for a nice dinner and then redeye to SIN with a short hop back to HAN.
I have done the JL F many times, but really keen to see how ANA, especially the new product, compares to JAL offering. I am very partial to japanese food and service!
Would love if they allow to reroute me SIN-HND-FRA-KBP on the return on SQ and ANA F as INVOL, though not sure they will - luckily again my TA is a skilled master of the craft!
