Taken from the Living Spain website:-
"To celebrate the launch of the new Living Spain magazine website we have teamed up with British Airways and you can win a pair of tickets to any BA destination in Spain"http://www.livingspain.co.uk/layoutBody/home.asp
Closes 26th October
Take note, if you win tickets it states you have to pay taxes and surcharges, "British Airways are offering a pair of free flights to any of their destinations in Spain, including the Balearics and Canary islands. All you pay are taxes, fees, charges and surcharges. For each passenger these are approximately £37.40."
At some times of the year you could probably get a return to Spain for this with a budget airline!
