Introduction

Based in Delhi, Indira Gandhi International Airport (IGIA) is the primary civilian aviation hub of the city. Named after the late PM Indira Gandhi, it is the busiest airport in India in terms of passenger traffic since 2009 and is also the busiest airport in the country in terms of cargo traffic.
As one of the busiest aviation hubs in South Asia, Delhi’s Indira Gandhi International Airport (IGIA) plays a critical role in connecting India to the world. However, starting April 2025, travelers using the airport should prepare for some turbulence—on the ground.

The Airport has temporarily shut down Runway 11/29 for essential maintenance work, which is expected to continue until mid-2025. This necessary update aims to enhance safety, improve operational efficiency, and extend the runway’s service life. But in the short term, it could mean longer wait times and travel headaches for passengers.

Why is the Runway Closed?

The closure of Runway 11/29 is part of Delhi International Airport Limited’s (DIAL) periodic infrastructure upgrade plan. Runways endure tremendous stress from constant takeoffs and landings. Over time, cracks, surface wear, and friction loss can develop—posing risks to flight operations.

Reasons for the Closure:

1. Wear and Tear from Heavy Usage
   Runways handle thousands of takeoffs and landings daily, which leads to gradual deterioration of the surface. Cracks, rutting, and erosion of the top asphalt layer can cause reduced friction—potentially affecting braking performance, especially during rain.
2. Upgrading to Meet ICAO Standards
   The upgrades are in line with global safety guidelines set by the International Civil Aviation Organization (ICAO). These standards require periodic resurfacing and system modernization to reduce operational risk.
3. Preparation for Future Growth
   Delhi Airport is expected to handle over 100 million passengers annually in the coming years. A robust, modern runway is crucial to supporting this surge and avoiding flight congestion or safety issues.

Scope of Maintenance Work:

• Complete Resurfacing
  The existing asphalt or concrete surface will be removed and replaced with a new, high-friction layer to improve aircraft handling during takeoff and landing.
• Advanced Lighting and Navigation Systems
  Runway 11/29 will receive Category I or II Instrument Landing System (ILS) upgrades, which aid pilots during low-visibility conditions such as fog or rain. New LED lighting systems will also improve visibility and energy efficiency.
• Improved Drainage Infrastructure
  Enhanced drainage will reduce the risk of water pooling (hydroplaning) and extend the runway’s lifespan, especially during Delhi’s monsoon season.
• Runway End Safety Area (RESA) Enhancements
  RESA zones will be reinforced to comply with safety norms in case of runway overruns or aborted takeoffs.

Impact on Flight Operations

With one of the airport’s three main runways out of commission, flight operations are expected to face temporary disruption, particularly during peak hours.

Here’s what passengers can expect:

• Flight Delays: Domestic and some short-haul international flights may face delays of 30 minutes to 2 hours.
• Rescheduled Flights: Some carriers may alter departure times to avoid congestion.
• Longer Turnaround Times: Aircraft may experience longer wait times for takeoff or landing, leading to schedule changes.

According to DIAL, efforts are being made to optimize runway usage and minimize the impact, but the sheer volume of traffic at IGI means that some delays are unavoidable.

Travel Tips for Passengers

To make your journey smoother during this period, keep these tips in mind:

1. Check Flight Status Frequently
   Use airline apps or the airport’s website to track real-time updates.
2. Arrive Early
   Give yourself extra buffer time—especially for early morning or late evening flights when delays are common.
3. Stay in Touch with Airlines
   Airlines may notify you of schedule changes or offer alternate routes. Keep your contact details updated.
4. Plan for Layovers
   If you’re connecting via Delhi, ensure there’s enough time between flights to absorb any delays.
5. Consider Alternatives
   If you’re flying short distances (e.g., Delhi to Jaipur or Chandigarh), train or road travel might offer more predictable timing during this period.

Conclusion

While the shutdown of Runway 11/29 may cause temporary inconvenience, it’s a long-term investment in safer and more efficient air travel. As Delhi Airport continues to modernize and expand, these upgrades are crucial to keeping pace with India’s growing aviation sector.

In the meantime, a little extra planning and flexibility can go a long way in making your journey smoother. Stay informed, stay prepared, and travel smart!

The airport handles over 1,200 flights a day, and even a small disruption can hinder the overall operation. Authorities are urging its passengers to be patient as these infrastructure improvements are intended to enhance long-term efficiency
