Great video! Very informative. Paris is also a similar case although it doesn't have as many major airports. But it does has CDG, Orly, Bourget, Toussus and numerous smaller airports.
The economy is not what it used to be. There is no room for the Concord. Airlines don't want to spend that kind of money anymore. Everyone wants B777s and A330s, and looks like the A350 is a big hope for many airlines. It's still an interesting read nonetheless.
