It is not the competing aircraft costing you extra money, but the fact that you are using these large aircraft. None of the large aircraft in AM are profitable. Large aircraft, like the DC-10 and L-1011, have huge maintenance costs and, due to the formulae used to calculate ticket prices, make proportionally far less money (not only are ticket prices much less when you use large aircraft, but long haul is also far less profitable than it should be, large aircraft are typically used for long haul).
My advice: sell them, use them on short haul between big cities or just accept that 200 million is the cost of being able to say you have a fleet of long haul DC-10s and L-1011s.
