obviously bored on a monday night - London Oxford Winston Churchill C.S.Lewis Inspector Morse University Airport is exactly 39.9 miles from Hillingdon (Greater London) which you might argue qualifies it for 'London' status don't you think?
If you lived say in Notting Hill, you're going to get to OXF quicker than it would take to get to Stansted - no question whatsoever.
Forget public transport, anyone in the markete to fly 'regional' drives.
