There is no airside connectivity between Terminals 1, 2, and 3. One major problem has been with connectivity between terminals. While IGI Airport might be one of the best in South Asia, its staggered development means that it faces several issues. While the terminal can quickly become crowded as traffic increases, it is undoubtedly far better than IGI’s older offerings. Terminal 3 has gone on to win several accolades for its service and design, elevating its global status as a hub. Terminal 3 marked a significant modernization of IGI, with its distinctive architecture and large spaces. In addition to international services, select airlines also moved their domestic operations to T3, including Air India. This marked the closure of T2 for renovations and the new terminal became the exclusive one for all international departures and arrivals.

T3 opened its doors in July 2010, a full 24 years since Delhi had a new terminal. While this is lower than other major airports globally, it is a significant increase from T1 and T2’s capacity. Led by the GMR Group and Fraport, T3 has the capacity to cater to 34 million passengers every year. The construction of Terminal 3 took place from 2006 to 2010, taking just over three years in total. This time, the government opted to hand over the management and construction of the airport to a private group, with the contract being awarded in 2006. Two decades after Terminal 2 opened its doors to travelers, Delhi once again needed a bigger and better airport for the growing passenger numbers. With more airlines serving India, T2 began filling up quickly too, with a need for more modern facilities. Terminals 1 and 2 were overwhelmed by the early 2000s, with T1 handling 45% more passengers than its capacity. However, aviation demand has grown exponentially in the last 20 years. While 1A is now closed, 1C serves as the domestic arrivals terminal and 1D for domestic departures. Terminal 1 was split into 1A, 1C, and 1D. However, the airport was expanded soon after, with a new terminal being constructed and completed in 1969 at the cost of ₹900,000 ($123,300) at the time, according to BusinessLine. At first, the airport could process a maximum of 1,300 passengers an hour, catering to the limited domestic and international flights. In 1962, Palam Airport officially became a passenger airport. After India’s independence, Palam continued to serve as an Indian Air Force base until the government decided to change its purpose due to the rise of commercial aviation in India. Palam first began as a Royal Air Force base during the Second World War, serving British war efforts in Asia and beyond. Indira Gandhi International Airport traces its beginnings back to the erstwhile Palam Airport. Delhi Airport is home to all of India’s major airlines and an important destination for scores of foreign carriers. Let’s dig into the past of IGI Airport and its rise to the busiest in India. However, the airport has a long aviation history, dating back to the 1930s. Delhi’s Indira Gandhi International Airport (IGI) is the busiest airport in India, catering to over 67 million passengers every year.
