Thanks for the info Oscar
For a couple of reasons I would prefer to stay higher than that, say at FL 070, which obviously extends the class A airspace significantly.
It is a bit of a hassle having to go down to 1500ft in Holland, not to mention that it's quite inefficient, you also can't do VFR-on-top. I was hoping for a special VFR all the way through the Netherlands basically.
any thoughts?
