I never heard about the special reduction (I'll have to read into it), anyhow I checked the ADP thing on HMRC, and then checked it against WebFlyer Mile Calculator and it's well within the 2001-4000 mile thing, I think it's really quite insane, I checked Halifax from LHR and it appears not to be exempt from the excessive ADP.

Reason: Found out Halifax isn't exempt.
