Delhi Airport Rain Disruption Delayed More Than 400 Flights on September 4

Source-checked update: This article brings together information checked against primary sources and independent reporting available at publication time. Full source links are listed at the end of the article.

Heavy rain and thunderstorms disrupted operations at Delhi’s Indira Gandhi International Airport on September 4, 2026, affecting flights and access areas during the afternoon. Nine flights were diverted between approximately 3:30 p.m. and 4:30 p.m., while more than 400 flights were reported delayed according to flight-tracking data cited by multiple news organizations.

The disruption was linked to severe weather in Delhi, including heavy rain and thunderstorms recorded by the India Meteorological Department. Water accumulated in parts of the airport’s approach-road and forecourt areas, although Delhi Airport said the water was cleared shortly afterward.

The verified disruption was concentrated on September 4. It should not be treated as confirmation of an ongoing major airport disruption on September 6, particularly as the IMD forecast showed no heavy-rain warning for Delhi from September 6 onward.

What Happened

Heavy rain moved across Delhi on September 4 as thunderstorms affected the capital and surrounding areas. Conditions disrupted flight operations at Indira Gandhi International Airport during the afternoon, with nine flights diverted to other airports.

Four of the diverted flights went to Jaipur, four to Lucknow and one to Ahmedabad. These are the destinations identified in the strongest independent reports about the event.

More than 400 flights were also reported delayed during the weather disruption. That figure came from flight-tracking data rather than a published airport or government operational total, so it should be understood as a reported estimate rather than an official airport count.

Rainwater accumulated in airport approach and forecourt areas, creating an additional access concern for travelers arriving at or leaving the airport. The airport said the water was cleared shortly afterward, but the episode demonstrated how quickly heavy rainfall can affect both airside operations and the journey to the terminal.

What This Means for Travelers

Travelers who were flying through Delhi on September 4 may have faced delays, missed connections or changes to their planned arrival airport. Passengers whose flights were diverted to Jaipur, Lucknow or Ahmedabad would have needed updated arrangements from their airline before continuing their journeys.

The reported delay total indicates that the effects extended beyond the nine diverted flights. Even when an aircraft is not diverted, thunderstorms and heavy rain can cause knock-on delays as flight movements are adjusted and aircraft or crews arrive later than planned.

Travelers should also distinguish between conditions at the airport and conditions on the roads leading to it. Water accumulation in approach and forecourt areas can make a journey to the terminal slower or less predictable, even when airport access is later restored.

However, the verified evidence does not establish that a major, airport-wide disruption was still continuing on September 6. The September 4 event was weather-related and time-specific. The absence of a heavy-rain warning in the IMD forecast from September 6 onward is relevant context, but it does not replace a direct check of an individual flight or ground-transport service.

What Travelers Should Do Now

Passengers with travel involving Delhi should check their flight status directly with the airline before leaving for the airport. This is especially important for travelers on connections, as a flight may be operating while a preceding sector has been delayed or changed.

Anyone whose itinerary was affected during the September 4 disruption should confirm the current booking, any revised routing and the airport from which the next flight will depart. Travelers should rely on the airline for rebooking or connection instructions rather than assuming that a diverted service will automatically return to its original schedule.

It is also sensible to check current airport access conditions before setting out, particularly after periods of heavy rain. Travelers using road transport should verify arrangements with the relevant transport operator or airport information service and allow flexibility for possible delays on approach roads.

If weather conditions change again, travelers should monitor updates from the India Meteorological Department, Delhi Airport and their airline. Forecast information can indicate wider weather risk, but only the airline or airport can confirm the operational status of a specific service.

Passengers connecting through Delhi may wish to avoid making tight onward arrangements until their flight status is confirmed. Where a connection is important, check whether the airline has issued any revised timing or rerouting information before traveling to the terminal.
