Re: Problem at Dubai just now?

A good test for the Emirates AOC. My guess as an outsider is that they will under deliver/ under perform, due to commercial elements having too much authority within the airline.

Re: Boeing CEO’s statement next new airplane will cost $50bn

They have to start spending billions up front before ever getting any revenue, time value of money eats into profitability. Imho, China and India will eventually g...

Re: A220 in Europe’s Airlines strategy

Starting with the CS500 would have put Bombardier dead in A/B’s gunsights. The point of the 100/300 was to offer a plane that wouldn’t go head-on against the duopoly. It was designed to be a regional plane with great field performance to serve small to mid-sized cities. It wasn’t designed for long,...

And what is amazing to me is that, apparently, Boeing wanted to cease the project in spite of that massive outlay of cash.
