This whole Sunweb charter deal sounds like something that didn't quite turn out as planned.
Had the SSJ100's arrived by now, they would probably have used one of those for the flights to Egypt. Which sounds like a pretty good way to make full use of these machines. As it stands though, I can't help but think VLM isn't - to put it mildly - making a ton of money fulfilling this contract with Sunweb.
