So now you're confusing me because you only just wrote that it is impossible to state whether any particular seat is profitable or not.Of course you can.
Fixed Cost: $10000
Variable Cost per pax: $100
Number of seats: 100
If QF only sells 100 x $120 fares, then each seat is at least meeting the marginal cost per passenger. But the plane will make an overall loss.
However, if QF can sell 50 $300 fares, and 50 $120 fares then the flight is profitable. Perhaps "subsidising" is not the correct word, since it's impossible to divide the fixed cost across pax until the number of pax is known. However without the expensive tickets being sold, the plane isn't going to fly.
The claim has been made that expensive fares subsidise cheap fares and the basis for determining that is how qantas set their fares.Sure you can say that qantas won't sell a plane load of cheap fares - we know that, based on our experience of buying tickets. There is no way to claim that a plane won't fly without expensive tickets being sold because qantas never sell only cheap seats. Then we have the example you gave of 1 J and 1 Y pax. That plane flew.
My contention is that in the example given there will be no fares lower than $200.
