I got to say that's its kind of ridiculous that there are like five Airbus' total and over 50 747s. Who could have possibly been able to use those 747s on day one?
In a sense, the demand for new aircraft is completely artificial. People are buying planes out of desperation. If I were Embraer I would be rushing 170s and 190s to market.
And realistically what broker would be sitting on aircraft (they have to pay for) with demand this high? And vice versa what broker would be flooding the market with 747s with demand so low and knowing all the airlines can't afford.
In real life, when you go to the bank to get a loan who would plan an airline without knowing they could or could not get planes?
