im sorry learjet50 but you clearly have know idea about the daily opperations of oxford airport, the airport never has a quiet day and i know this because i fly from it everyday, just read this link
London Oxford (Kidlington) Airport EGTK/OXF - London Oxford Airport reports busiest weekend to date
as for commerical flights, its jersey route is very popular and on many flights it is completely full, this is definately one small airport thats time is definately not up.
can i also add that the only reason varsity express was not successful was beause its owner did not pay the aircraft lessor.
