The AFR lump at EDI was probably bringing in French supporters for a Scotland Vs France rugby match. These Rugby matches (along with Scotland vs Ireland) bring in a large amount of visitors, both airline & GA to the airport.
The same goes for Cardiff airport for Wales vs France/Ireland rugby matches, the airport attracts plenty of fixed wing visitors (again airline & GA) with any overspill going to Gloucester, Bristol Filton & occasionaly Bristol Lulsgate.
