India's aviation sector is set for a significant expansion in 2026 with the upcoming operationalization of Noida International Airport at Jewar and Navi Mumbai International Airport. These new greenfield airports aim to alleviate congestion at Delhi and Mumbai hubs, offering airlines capacity for new flights and improved operational flexibility. The expansion is expected to broaden aviation catchment areas and facilitate more domestic and potentially international routes, though airlines still face challenges like crew shortages and supply-chain disruptions.
