How to become a expert in Flight Operations Business? (Flight Dispatch, Weight and Balance etc.. )
It depends on where you are located and what country you are located in as to what kind of license will be beneficial to you. If you are in the United States, obtaining a FAA dispatch license is a common route to working in flight operations. There are community college programs to prepare you to take the exams. The benefit to the FAA license is it never expires. In other countries there are similar licenses you can obtain. I would be cautious to IATA programs mainly due to the price and many are geared towards existing professionals in the industry.
