The percentage of all international passengers flying to and from India that are served by Indian airlines as opposed to foreign airlines is known as the Market Share (%) of Scheduled Indian Carriers and Foreign Carriers in Terms of International Passengers Carried in India. This metric aids in assessing how international traffic is split between domestic airlines like Vistara, IndiGo, and Air India and international carriers like British Airways, Singapore Airlines, Emirates, and Qatar Airways. In order to determine how the international aviation market is split between Indian and international airlines, market share is usually computed as a proportion of the total number of passengers carried internationally over a specific time period. When evaluating the success and competitiveness of India’s aviation sector, this metric is quite relevant. Increased fleet capacity, better worldwide connectivity, and greater trust in Indian aviation services are all indicated by an increasing market share of Indian carriers. On the other hand, a large percentage of foreign carriers may indicate solid international alliances, but it also emphasises the necessity for Indian airlines to become more competitive and expand. This measure is crucial for policymakers to assess bilateral air service agreements, tourism inflows, and trade facilitation. It also influences strategic choices about route diversification, infrastructure development, and India’s goal of becoming a significant international aviation hub.
