Hi Charlie,
I have a ppl and live near to Malaga. General aviation, down here, is nothing like in the UK as it seems to be purely for the wealthy and elite few.
There is a flying club at LEAX and I called them to enquire about membership and was told that membership only cost 3,000 euro each year. On top of that they sounded unfriendly and indifferent to my enquiry.
I have been down to fly-in-spain at Jerez and found them very proffesional and friendly and would reccomend them, but, Jerez is a two and a half hour drive from Malaga.
Recently I found a guy based at LEAX that advertises flying lessons and aircraft rental. I phoned him and he speaks English and sounds very friendly and helpfull. I have'nt got round to going over there for a flight yet so can't give any reccomendations.
Take a look at
