"London Oxford Airport" - they're having a laugh aren't they?
Go to the Oxford Airport website and you'll see they have just re-badged themselves as a London airport!
It has taken many years for me to sometimes refer to Luton as "London Luton" and I only finally did so because I realised it is a few miles nearer London than Stansted, which I have always considered to be a London airport, largely because it was only there in the middle of the countryside for one purpose (to be a London airport) and has a dedicated rail link....and it still sticks in my throat!
London airports (the only ones that will ever be refered to by me as London airports)...
