I mentioned BRS-GVA as a possible route
Ah, I see. Yeah, it's a possibility.
I just returned from an 12 hour overland trip from East Yorkshire to Devon (my home county). It took so long because I did it by National Express - it would have taken perhaps 8-9 hours by car and cost much more in fuel. If only there was an air connection between an airfield near Bridlington and BRS or better still the minute airfield near me.
