Thanks for Clarification SSK
and yes
Correct me if this wrong, but AFAIK, it can be done one ticket, by booking a multi-sector journey, with a 24 hour stopover at the European hub on the outward journey, e.g on KL: LHR-AMS on monday; AMS-NRT on tuesday.
That was my take re outbound !
Plus the price differentials between using what can be descibed as "dumped capacity" is lower than premium service direct...its completly skewed when there are multiple examples of fares like;
£700 Manchester - Newark
£300 Manchester CDG - Newark
