Hi Balaji,

The eligibility for air hostess course:
Age- 17 to 24 years.
Minimum Qualification- 12th pass and above, having a pleasing personality and good communication skills.
Selection procedure- The selection will be on the basis of personal interviews.

Both are good. I think that for becoming a director, more than your qualification, your creativity matters. You should have a good sense of people's emotions, wants, and opinions. You should think out of the box.
As such, in my opinion, a certification course can give you many new opportunities.
