I assume from the absence of any further postings on this subject that there is no problem with transits (or you're all still holding awaiting clearance). Thought so. ATC's job is not to disrupt you as many seem to think, and from my time at Liverpool, I can't remember denying anyone a VFR transit either. Since DSA's radar service is provided by the same controllers, the same would go for Donc. Most ATCO's take pride in moving the traffic and giving the pilots what they want whenever possible. From my experience as a DSA radar controller it is much easier to give a control service rather than a RIS or RAS.
I get the impression from some posters that it is felt that the provider, in this case Peel, has a policy about who can and can't transit the airspace. I can state categorically that this is not the case. It is purely the ATCO on the day who decides, and this is based purely on the traffic situation at the time. I can't speak for other service providers though.
