A late-night thunderstorm fuelled by a western disturbance barrelled across Delhi on 4 May, forcing the diversion of 24 aircraft from Indira Gandhi International Airport and prompting the India Meteorological Department (IMD) to issue a red-then-orange alert for the capital. Wind gusts reached 70 km/h between 23:30 and 00:30, toppling ground-handling equipment and delaying dozens of departures. Airlines rerouted flights to Jaipur, Lucknow and Ahmedabad, while Vistara and IndiGo waived change fees for affected passengers.

Travellers unexpectedly rerouted or facing extended layovers may also discover unforeseen visa or transit-document requirements. VisaHQ’s online platform (https://www.visahq.com/india/) can rapidly check entry rules for alternate airports, arrange emergency e-visas, and even courier renewed passports, ensuring that weather-induced detours don’t turn into compliance nightmares.
The disruption highlights the vulnerability of India’s busiest hub at the start of the pre-monsoon season. Mobility managers should note that the Directorate-General of Civil Aviation (DGCA) has instructed carriers to ensure minimum fuel reserves for 45 minutes of holding plus one alternate airport until 15 May. On the positive side, the storm slashed Delhi’s Air Quality Index from 175 (moderate) to 88 (satisfactory), allowing the Commission for Air Quality Management to lift Stage 1 restrictions under the Graded Response Action Plan. However, IMD warns of another thunder cell on 6 May, suggesting continued schedule volatility. Travellers transiting Delhi this week should build in longer connection windows and monitor airline apps for gate changes; corporate travel policies may need temporary flexibility on missed onward flights.
