The Indira Gandhi International Airport (IGIA), New Delhi has been declared the World’s 4th Best Airport and APAC’s Most Improved Airport for Airport Service Quality (ASQ) in the 15 to 25 million passengers category by the Airports Council International (ACI). In 2006 when its transition was effected, IGIA’s ASQ rating was 3.02 points, which went up to 3.15 points in 2008. This figure jumped to 4.16 points for the year 2009. Being a brownfield project, this spectacular improvement in such a busy airport is a very special and rare achievement.
