What is the most cost effective route to Heathrow?
I might have some spare time coming up, which gives me an opportunity to burn some Avios.
The cost of travelling to Heathrow and parking would dwarf the cash I'd have to spend on Avios redemptions to Europe.
I'm trying to find the cheapest route to get to, and fly out of Heathrow.
I live in the Midlands.
I wouldn't want to hitch, but would welcome any ideas, knowledge or sensible (!) suggestions people might have?
Are there any threads/websites I should be reading?
