Age 34! Finished IR/MCC at age 37. First TP job a few months later. One year on the Dash 8 then Airbus with a Big Airline. Five years on and looking forward to 777 course in the hopefully not too distant future or perhaps hanging on for a 380 course. All depends on your attitude to risk, critical assessment of your own potential and ability, commitment, cash and support from your nearest and dearest.
