Is that likely to work?

I fly IFR into Ontario, California IFR on my run and do it VFR on top as
much as possible. It cuts down on our run time as we fly a more direct
route, and since we are on a schedule it helps a lot.

ATC may, after all, deny the "on top" clearance.

They can, but unlikely. It frees up the controller to focus on other
things.


That certainly makes sense. But what about when I want to return to (let's
call it) "full IFR". I could be well off my flight plan at that point,
right? It may mean less work in the short term, but possibly more work
long term (for the controller).

Of course, perhaps the controller can hope that this'll be the next guy's
problem laugh.
