The most 'in demand' job in the airline industry is the cabin crew. The most important work of a cabin crew personnel is to take care of the passengers, answering to their queries and cater to their needs, serving snacks, drinks and meals to the passengers, applying first aid if situation arises etc. To become a qualified cabin crew, you need to obtain a certification for it. For this, you can join institutes that conduct the courses for air hostesses and flight stewards. These courses train and groom you for the airline industry and the duration of such courses is normally 1 year or sometimes more than that. The eligibility criteria for such courses is a higher certificate secondary or an equivalent. Most people think that cabin crew jobs are mostly meant for women and men do not have enough opportunities in it! However, I would partly agree to it, as each and every airline requires flight captains and therefore, there are ample career opportunities for men too.
