Since your world switched to company currencies, the route planner's "Earns a week" and "Breaks even" box showed the wrong numbers for any airline not using US dollars. It was reading your fares as dollars.
So yen, yuan, lira and francs made routes look way too good (lots of "breaks even 0%"), and pounds and other strong currencies made them look about half as good as they were. Japair's Osaka-Singapore showed 57 billion yen a week at 0%. It now shows about 354 million yen at 9%.
Fixed at 04:51 UTC today. Only the estimate was wrong: your bookings, revenue and route accounts were always right. If you planned routes off that box, it's worth a look at how they're actually doing.
