The India Meteorological Department (IMD) issued a red alert for Delhi/Delhi‑NCR on and around 24–25 August 2026, as heavy monsoon showers caused widespread waterlogging and significant traffic disruption across parts of Delhi and neighbouring National Capital Region districts.

Flight operations at Indira Gandhi International Airport (IGI) were disrupted on 24 August 2026. Multiple inbound flights were diverted and many services were delayed or cancelled. Multiple outlets reported that about 15 flights were diverted from Delhi (with examples given of diversions to Jaipur, Chandigarh and Lucknow).

Reported counts of cancellations and delays vary across outlets. Some reports cited roughly 20–26 cancellations and described hundreds of delayed flights, with figures reported in different outlets including 'more than 200', 'over 280', and 'around 390–400' delayed flights. News reports commonly attribute the disruption counts to a flight‑tracking platform (Flightradar24) or to unnamed airport or aviation officials.

Airlines named in reporting issued advisories to passengers to check flight status and to expect potential weather‑related impacts.

The coverage and disruption figures reported by outlets refer to events occurring on or around 24–25 August 2026.
