Delhi International Airport Limited (DIAL) has announced that approximately 114 daily flights, accounting for about 7.5% of total daily aircraft movements, will be cancelled from June 15 to September 15 as part of a major upgrade to runway 10/28.
The Indira Gandhi International Airport, the largest and busiest in India, handles around 1,450 aircraft movements per day. The closure of runway 10/28 for the upgrade will reduce daily movements by this amount during the three-month period.
DIAL CEO Videh Kumar Jaipuriar explained that the cancellations, which are higher than the usual 3-4% daily cancellations, have been coordinated in advance with airlines to minimize disruption. Flights have been rescheduled to reduce cascading delays and provide passengers ample time to make alternative arrangements.
The runway upgrade involves installing an advanced Instrument Landing System (ILS) to make the runway compliant with CAT III-B operations, a precision landing system that enables aircraft to land safely in very low visibility conditions such as dense fog. This enhancement aims to improve operational reliability during the fog season.
Originally scheduled for April-May, the upgrade was postponed due to unexpected wind pattern changes causing severe flight delays. Following directives from the Ministry of Civil Aviation, the runway was reopened on May 6, and the upgrade rescheduled for June 15 to September 15, with agreement from all airlines.
The airport has four runways and two operational terminals (T1 and T3), with T2 currently closed for maintenance. The upgrade is expected to enhance safety and operational efficiency during adverse weather conditions, particularly winter fog, by improving landing capabilities on runway 10/28.
Passengers are advised to check with their airlines for updated flight schedules and make necessary travel arrangements in advance.
