I think a IST-MAN-LAX would work very well.
Why not IST-LAX direct?
BD would certainly help fill the plane, if LH allow them to take some of their traffic from their own German connections!
Ja, our planes are much too full and profitable so let's send our passengers on two partner airlines to the US. NEIN!!!!!
The route must be one of their best performing 2-class routes on their network and I think it can take an F class service!
No no no no no no! Quickest way to ruin a route is to assume that. There is almost ZERO proper F class demand outside of London. Lots of business class of course but First? Even premium flunkies BA are removing First from their new B777s from Heathrow. Singapore might use an F class aircraft but only because they are juggling aircraft, certainly little call for F on a non daily service.
