Delhi’s Indira Gandhi International Airport (IGIA) has been ranked number one in the world on airport service quality ranking. Last year, in the highest category of handling over 40 million passengers per annum (MPPA), IGIA was number two, along with Singapore’s Changi Airport and after South Korea’s Incheon airport.
With 63.5 million passengers flying through the Delhi airport in 2017, it has surpassed Changi, Incheon and Bangkok airports in terms of passenger growth. It is now the seventh busiest airport in Asia and among the top 20 busiest airports across the world.
Airports Service Quality (ASQ) is the only worldwide programme to survey passengers at the airport on their day of travel. The programme measures passengers’ views on 34 key performance indicators, including airport access, check-in, security screening, restrooms, stores, and restaurants.
In 2011, the airport had achieved the position of World No. 2, which it retained for three consecutive years till 2013.
