Re: It all works fine in theory
"Surely it can't be cheaper to have your planes grounded by the civil aviation authorities......
The issue here is that it costs Boeing nothing while the planes are grounded. They can still demand that the airlines pay for the planes even while they're not flying. The *lawsuits* from the airlines *after* the fact might cost Boeing something, but thats for the lawyers to fiddle with, not the beancounters.
