Delhi rains disrupt IGI flights as IndiGo, Air India urge flyers to plan ahead

Persistent heavy rain over Delhi on September 4 led to waterlogging at Indira Gandhi International Airport and widespread disruption to flight schedules, prompting major carriers IndiGo and Air India to issue travel advisories urging passengers to plan extra time and monitor real-time updates.

Heavy downpour triggers flight disruptions at IGI Airport

Delhi’s latest spell of intense monsoon rain on Friday brought operations at Indira Gandhi International Airport under strain, as water accumulated on approach roads and parts of the forecourt while low visibility and strong winds slowed aircraft movements. Published coverage indicates that at least nine flights were diverted from Delhi between 3:30 pm and 4:30 pm, with services rerouted to Jaipur, Lucknow and Ahmedabad as pilots avoided the worst of the weather.

Reports from multiple outlets describe a rare squall over the airport area, with wind speeds reaching around 76 kmph and visibility briefly dipping to about 600 metres. These conditions, combined with heavy rain, affected both arrivals and departures and led to holding patterns in the air and knock-on delays across the evening schedule.

Publicly available information shows that arrivals from key domestic sectors, including Ahmedabad, Mumbai and Port Blair, were among those experiencing delays as the weather system moved over the capital. While some of the waterlogging around terminal access roads was brought under control relatively quickly, traffic congestion and ongoing showers continued to slow passenger movement to and from the airport.

IndiGo issues advisory as IMD maintains red alert

Low-cost carrier IndiGo, which operates the largest share of domestic flights from Delhi, published a travel advisory on Friday warning that bad weather across the National Capital Region was affecting flight operations. According to news reports summarising the advisory, the airline asked passengers scheduled to fly from or into Delhi to keep checking their flight status on digital channels and to allow additional travel time to the airport as city roads faced heavy waterlogging and traffic snarls.

The advisory came as the India Meteorological Department maintained a red alert for the city, highlighting the potential for intense rainfall and thunderstorms over short periods. Coverage of the weather bulletin notes that the alert was issued for September 4, with a subsequent yellow alert outlining the likelihood of continued light to moderate showers and storms into Saturday.

IndiGo has issued similar advisories in previous weather events, including earlier spells of rain and winter fog, typically advising travellers to arrive early, track their flights closely and be prepared for last-minute schedule changes. The latest message fits that pattern, with the focus on minimising disruption for passengers while the airline adjusts its operations around adverse weather.

Air India joins calls for passengers to monitor flight status

Full-service carrier Air India also shared a passenger advisory in response to Friday’s disruption, according to business news coverage of the event. The airline alerted customers that heavy rain and low visibility in Delhi could lead to delays and short-notice alterations in flight timings, and it encouraged travellers to use official web and app channels to confirm their departure and arrival details before leaving home.

Recent press clippings compiled by the Airports Authority of India show that Air India routinely adopts a similar approach during major weather events, from intense rain to dense winter fog. In past disruptions, the airline has used social media and direct passenger notifications to signal that flights may be rescheduled and to reassure travellers that options such as rebooking or onward assistance will be managed through standard customer-support channels.

On Friday, the combination of advisory messages from IndiGo and Air India, together with an alert from Delhi International Airport, underscored how even a short but intense burst of monsoon weather can ripple through operations at India’s busiest hub, which typically handles more than 1,300 flight movements a day.

What travelers flying through Delhi should expect

With the IMD forecasting the possibility of additional rain and thunderstorms around the capital, passengers flying into or out of Delhi this weekend can expect some residual impact on schedules, even as water recedes from key access routes. Airlines often need several hours to reposition aircraft and crews after diversions, and delays at one end of a route can cascade across a wider network through the day.

Publicly available information from airline websites and historical advisories suggests that travellers may see longer-than-usual queues at check in, security and boarding if several flights depart within short windows once weather conditions improve. Services that connect through Delhi to other Indian cities or international destinations can also experience revised timings as carriers work to restore normal rotations.

Travel reports covering past disruption at IGI Airport indicate that while the airport infrastructure is designed to handle heavy rain, short bursts of intense downpour can still create temporary waterlogging in some landside areas and on approach roads, especially when combined with peak-hour road traffic. That can add unpredictable time to the journey from central Delhi or neighbouring NCR cities to the terminal.

Practical tips for passengers during weather-related disruptions

Recent advisories from IndiGo, Air India and the airport operator point to several steps that can help passengers navigate days like Friday, when weather and operational pressures coincide. Travellers are encouraged to confirm their flight status on airline websites or mobile apps shortly before departure, as these platforms tend to carry the most up-to-date information on delays, gate changes and diversions.

Given the reports of waterlogging between central Delhi and IGI Airport, passengers heading to the terminals are likely to benefit from leaving significantly earlier than usual and building in a buffer for traffic congestion. Those using public transport or app-based taxis may want to check for rerouting or surge conditions during and immediately after heavy showers.

Airlines also generally recommend that customers ensure their contact details are correctly entered in their booking records, which allows automated notifications about significant schedule changes to reach them quickly. For international journeys or tight onward connections, passengers may wish to keep flexible arrangements where possible, in case local delays in Delhi affect downstream segments of their itinerary.

Relying on official channels and verified news outlets for updates can help travellers distinguish between temporary slowdowns and more sustained disruption as Delhi works through the latest bout of intense monsoon weather.
