hello Sam
I learnt to fly at LGC - in GBP and EVX and FBV and what I learned gliding has been invaluable over the years. I towed gliders at various UK clubs to build hours and flew aerial survey, aeromedical and charter piston twins to get my career going. I moved to business jets and am now sitting in Tortola in the BVI having just done a tour all round South America. The work is very varied and I still enjoy it enormously. Don't restrict yourself to the airline dream - whilst that can still be a very good career there are other ways to make a decent living in aviation. Keep gliding - you will find that the contacts you make through the sport will be invaluable to you as you progress.
good luck chap - go buzz the flamingos for me..
