Significantly, Air India was one of leading contributor in Changi Airport's traffic growth from the South Asian carrier in 2015.
The flag carrier currently operates 42 weekly flights between India and Singapore, with daily services from Delhi, Mumbai and Chennai.
"The airline (Air India) registered a strong 25 per cent year-on-year growth in passenger carriage on its Singapore routes in 2015, largely spurred by an increased passenger capacity due to aircraft upgrade, as well as an expansion of routes in the last two years," according to Changi Airport statement.
Changi airport had logged a 2.6 per cent growth in 2015 with 55.4 million passengers using the airport last year and Indian fliers accounting for a little over six per cent in the overall growth.
