Regional Air Connectivity in India is growing rapidly. The government aims to connect smaller cities and regions through a 4-tier model using aircraft of different sizes. Over the past decade, domestic passenger traffic has grown by 14.2% annually and India now has the 9th largest aviation market. However, connectivity and air travel penetration remain low compared to other countries. Expanding regional connectivity through initiatives like non-scheduled permits and smaller aircraft can help develop the civil aviation sector and connect more of India's population. Challenges include high fuel costs and the need for government support of regional routes.
