ayebmi, hardly surprising they can't make money using a 330 with 220 seats on a route (TLV) you can use a 737NG or 757.
That tho is the least of their problems: even on RUH with the dearest economy seat £447 to the cheapest,THY £286, for the same dates in Feb the 330 lease must be astronomical!
On the same dates the VS Y ticket to BGI is about th same price per nm as the bmi ticket to RUH so the Caribbean could easily be profitable given the right lease rate.
