The problem with the concorde is that the game system does not factor in the increase in price that ppl (irl) are willing to pay in order to get to their destination quicker. What ends up happening is that you would be fighting spamlines with a plane that has a higher running cost with lower amount of seats. And we all know that you end up loosing a lot of money this way...

You'll have to wait for the admin to reset the world. Usually ain't too long!

I've mentioned this before. Ratio of F to Y should be 3:1 and C to Y 2:1. Sadly we'll probably never see these changes implemented

Fuel flow is a measurement of how much fuel each engine on that type of aircraft consumes per unit of measurement. Preferably you would want to choose an aircraft with lower fuel flow as that would mean less fuel consumption and therefore less money spent on fuel but bear in mind that this could also directly affect the speed at which the aircraft cruises (though in the game the differences are minimal). Newer aircraft also tend to have lower fuel consumption than older ones.

Is it specifically in your world? might be the game struggling to deal with all those spamliner orders...
