planes like cars
I think MOL needs to also think resale value, ie after he has these mystery jets for 5 or 10 years will he be able to sell them for anything? There's a reason BMWs and Mercedes cost more, they hold their value, and that has a huge impact on total cost of ownership calculations..
Of course the manufacturer may offer to buy their own jets back for a fair price, as the leverage they would get from exposure to a Western airline would be huge...
