Heavy Rain Disrupts Delhi Flights as IndiGo Issues Travel Advisory

Heavy rain and thunderstorms disrupted flight operations at Delhi’s Indira Gandhi International Airport on September 4, 2026, creating diversions, delays and difficult road access to the airport. IndiGo issued a weather-related travel advisory as the India Meteorological Department continued to forecast heavy rain over Delhi for September 5 and September 6.

Travelers flying through the Indian capital should check their flight status directly with their airline before leaving for the airport and allow additional time for the journey. Conditions on September 5 have not been established as fully resolved or continuing at the same scale as the previous day, so passengers should avoid assuming that schedules are operating normally.

What Happened

Heavy rain and adverse weather affected operations at Delhi airport on September 4. At least nine flights were diverted: four to Jaipur, four to Lucknow and one to Ahmedabad. The disruption also involved flight delays, waterlogging at the airport and slower access for travelers approaching the terminal.

IndiGo advised passengers that bad weather over Delhi had affected flight schedules. The airline’s guidance was for travelers to check their flight status and allow extra travel time, reflecting both the impact on aviation operations and the difficult conditions on the ground.

The weather risk remains relevant because the India Meteorological Department issued a heavy-rain warning for Delhi for September 5 and September 6. That forecast supports continued caution for travelers, although it does not establish that flight operations on September 5 are experiencing the same level of disruption recorded on September 4.

What This Means for Travelers

Passengers booked to or from Delhi may face changes to departure times, aircraft routing or arrival arrangements if heavy rain affects airport operations. A flight may not be canceled but could still be delayed or subject to operational changes, particularly when severe weather affects aircraft movements and access around the airport.

Travelers should also factor in the journey to the terminal. Reported waterlogging and slower access mean that a normal road journey may take longer, even if the flight itself remains scheduled. This is especially important for passengers with fixed check-in deadlines, onward connections or time-sensitive ground transport.

Passengers connecting through Delhi should review the status of both their flight into the airport and their onward sector. A delay or diversion on the first leg can affect a connection even when the second flight has not yet been shown as changed. Travelers with separate tickets or prearranged transport may need to reassess those plans directly with the relevant provider.

The available information confirms significant disruption during September 4, but it does not confirm that all flights are currently affected or that conditions have returned to normal. The safest approach is to treat the forecast as a reason for active monitoring rather than as proof of a specific delay or cancellation.

What Travelers Should Do Now

Check the latest flight status directly with the operating airline before setting out for the airport. If the booking involves more than one airline, check each sector with the carrier responsible for that flight. Do not rely only on an earlier confirmation if travel is scheduled during the period of heavy-rain warnings.

Allow extra time for the journey to Delhi airport. Reported waterlogging and slower access can affect road travel, so passengers should build in a larger buffer than usual for reaching the terminal, completing airport formalities and getting to the gate.

Keep monitoring messages from the airline and be prepared for a schedule change, diversion or other operational adjustment. If the airline changes the itinerary, confirm the new departure airport or timing before traveling to the terminal. Passengers whose plans depend on a connection, hotel booking or onward transport should contact the relevant operator if a delay creates a practical problem.

Travelers who are already at the airport should follow airline and airport instructions and allow for possible delays. Those who have not yet started their journey should verify the latest position first, particularly if local rain or road conditions are deteriorating.
