flower,
you were answering bpilatus' post.
I wasn't having 'ago' at anyone, just pointing out that GA do pay when GA use the service, which is a common misunderstanding because I've had this discussion before...
BTW, you attract charges without using airways too - this is another misunderstanding.
File IFR = incur charges. Even if it's night and there's no VFR because everything (UK) is IFR at night...
Anyway, back to NOTAMs
