Remember, if there's no competition, you can easily raise price to at least 30% above the suggested value once the route is mature. Without stopovers you could even go a little higher maybe.
On my JFK-Japan routes a typical financial overview for a Connie is:
Ticket Sales $51,100
(it flies a shorter route too, so the figures are just for comparison).
Now, when I up the prices of the Japan flights by 30% I get:
Ticket Sales $65,700
SO a 30% increase in tickets give me approximately an 88% increase in profits.
