I know that route frequency is important in a way that flying a route 2/3 times per week is not good. But considering the LH flights that last more than 11 hr one way, then plus the turnaround, which more than likely, would take more than an hour, the total would take more than one day. That means I need 2 aircraft to fly that route 3 alternate days per aircraft (of course they would fly some other routes as well). And if I want to fly that route for the whole week, that means I need 3 aircraft and their pattern would be like 2/2/3 or 3/3/1. I know that the profit margin on LH or even ULH routes is not that much anyway, but apart from this, would the load factor suffers as well, which in turn affects the revenue on this route?
