In recent developments, Delhi Airport’s Phase 3A expansion has unveiled the upgraded Terminal 1 facility, marking a significant milestone in India’s aviation landscape.

This expansion project anticipates a doubling of annual passenger traffic. The upgraded Terminal is equipped to handle up to 40 million passenger movements per annum.

Apart from the integration of Arrivals and Departures of T1, GMR Airports-led DIAL has undertaken other development projects.

This will make Delhi Airport future-ready, keeping in mind its goal to become a Net Zero Carbon Emission Airport by 2030. A range of upgrades both passenger side and airside are under work.

Fourth Runway

The cornerstone of the Phase 3A Expansion project is the construction of a new 4.43-kilometer-long Code F runway, commonly referred to as the fourth runway.

Situated on the Southern Airfield, this addition positions Delhi Airport as the sole Indian airport boasting four operational runways.

The fourth runway not only accommodates increased air traffic movements but also enhances operational flexibility with dual elevated Eastern Cross Taxiways (ECT).

This infrastructure reduces taxiing time, CO2 emissions, and ensures swift emergency response with the establishment of a new fire station on the airside.

Primary Runway Rehabilitation

Delhi Airport has refurbished the British-era runway (RWY09/27) as part of its expansion endeavors. This rejuvenation aligns with Category-I (CAT-I) Instrument Landing System (ILS) standards, enhancing pilot assistance during low visibility conditions.

The realignment of a new taxiway reduces Runway Occupancy Time (ROT) and improves traffic flow.

Additionally, upgrades to the Airfield Ground Lighting (AGL) system ensure operational reliability and efficiency, further bolstering safety measures.

Dual Elevated Eastern Cross Taxiways

A pioneering feat, the dual elevated Cross Taxiways on the Eastern side of the airport connect the Northern and Southern airfields.

These taxiways significantly reduce taxiing distances, aircraft emissions, and operational costs while enhancing efficiency and passenger experience.

By streamlining taxiing routes and operations, approximately 55,000 tonnes of CO2 emissions are curtailed annually.

Moreover, passengers benefit from reduced taxi distances, ensuring a quick transition from runway to terminal.

Terminal 3 Upgrades

Modifications in Terminal 3 aim to elevate passenger comfort and convenience. The International-to-International transfer area has nearly doubled, while the addition of a 7th check-in island and Self Baggage Drop facility enhances operational capacity.

Upgraded IT systems streamline baggage handling, ensuring trouble-free transit for passengers.

These enhancements project a substantial increase in passenger throughput, enhancing overall airport efficiency.

Flyovers: Facilitating Transit

To streamline traffic movement and provide a hassle-free transit experience, Delhi Airport has introduced two flyovers: the Aerocity Flyover and the Parallel Access Road flyover.

The Aerocity Flyover, a four-lane one-way structure, facilitates signal-free movement from Terminal 1 to Terminal 3, reducing travel time significantly.

Meanwhile, the Parallel Access Road Flyover segregates heavy vehicular traffic, easing congestion and ensuring smoother airport approach roads.


Delhi Airport’s Phase 3A Expansion exemplifies a holistic approach towards modernizing aviation infrastructure.

The project sees runway enhancements to terminal upgrades and innovative traffic solutions. Each facet of this project is clearly geared towards enhancing efficiency, sustainability, and passenger experience

With the Indian aviation sector seeing robust expansion, Delhi Airport is positioning itself with a future-ready, eco-friendly travel ecosystem.
