Interesting......I don't have one here unfortunately. But is this a VFR corridor, in the sense that you can just fly it that doesn't require a clearance (like the Manchester LLR) or is it a transit that is normally approved.TIA.
No it isn't really a corridor - it's more of a suggested route with an entry and exit VRP.
Personally I've never used it. Just call up Luton (usually the same person works Stansted and Luton but different frequencies) and ask for a transit. Again, you may end up having to hold, but they're pretty good.
