The aviation industry in India is one of the fastest growing in the world due to government reforms and policies. It contributes around 0.5% to India's GDP currently but is expected to contribute 5% by 2030 due to strong annual growth rates of around 24%. Key factors driving this growth include rising incomes, increased tourism and business travel, and competitive domestic airlines. However, challenges remain around modernizing fleets, expanding airport infrastructure, and reducing costs. The government is seeking to address these through policies to attract foreign investment, develop regional airports, and upgrade major hubs to handle over 100 million passengers annually by 2020.
