If you are an expat like me or own a place in Spain and spend more time than you would like to at or between airports, then you ought to meet Gary Ingram. He runs a great site called Spanish Airport Guide and is more helpful than your average trolley dolly.
Gary has researched all the airlines, their destinations, the cheapest car hire and transfers at pretty much every airport in Spain. He currently runs a message board where he answers any questions and posts travel tips like how to save money on flights, for example.
In fact his message board has become so popular, he is looking at turning it into a forum, so he can answer more of your questions. Isn't he good?
