hi ramy
so nice to meet you
to join airline like egypt air ..you must wait till egypt air needs employee and the other airlines will get its employees from travel agents
so the chance first will be in travel agent
if so ..you must have a good knowledge about the computer system used in this field
so u can attend course in arab academy in alexandria to study amadeus system ..after that and after you have a chance in travel agent you can study a iata diploma
with my best wishes
