Hello Ahmad2021,
An individual must be 16 years old to solo an aircraft, 17 years old to obtain a Private Pilot Certificate, 18 years old to obtain a Commercial Pilot Certificate and 23 years old to obtain an Airline Transport Certificate. FAR Part 121 (major airline regulations) require all pilots to retire at the age of 65.
Many Epic students from outside of the US will return to their home country to seek employment once they have completed their pilot training at Epic Flight Academy.
Every airline has its own set of hiring requirements, and we encourage our students to review a particular airline’s hiring requirements before applying for a First Officer or Captain position.
Here is an article on hiring requirements for airlines around the world: https://epicflightacademy.com/commercial-airline-hiring-requirements/
