"ere is no reason that modern variants of the 747 can't compete against new comers"
Except the newer designs will still use less fuel, even if that fuel does cost less. That extra cost means your prices need to be higher than your competitors to cover your costs. That means using one puts you at a competitive disadvantage. Comparison websites and dynamic pricing and all that mean that you only have to be $1 more expensive to lose customers.
