There's only so many pax flying to/from and or through Haneda/Narita. It seems Delta would rather have a code share and diminish our Narita flying. Put another way, is there more $$$ to be made for Delta through a code share than by flying the pax ourselves? I'll take a guess and say the final product IF this deal goes through will be a combination of JV (Haneda) and our own flying (Narita).
