Airport History
Indira Gandhi International Airport traces its origins to Safdarjung Airport, which served as Delhi’s primary airport before the development of a larger facility became necessary. As air traffic increased in the mid-20th century, a new airport site was established at Palam, which eventually evolved into the modern airport.
The airport was officially renamed Indira Gandhi International Airport in 1986 and gradually expanded to accommodate growing passenger demand. Over time, new terminals and runway infrastructure were developed, allowing the airport to handle increasing domestic and international traffic.
A major milestone in the airport’s development was the opening of Terminal 3 in 2010, built ahead of the Commonwealth Games. This terminal significantly increased capacity and introduced modern passenger facilities, helping transform the airport into a global-standard hub.
In recent years, continued expansion and modernization projects have further improved infrastructure and operational efficiency. Today, Delhi Airport stands as one of the leading aviation hubs in Asia, balancing high passenger volumes with ongoing development to support future growth.
