Delhi flights hit by weather chaos as over 500 delays reported

Heavy rain and hail over Delhi in recent days have triggered extensive disruptions at Indira Gandhi International Airport, with more than 500 flights reportedly delayed and travellers facing long queues, missed connections and diversions across the network.

Stormy skies trigger cascading delays across IGI

Published coverage from Indian media and aviation trackers indicates that a powerful spell of rain, thunderstorms and pockets of hail over the Delhi-NCR region led to widespread disruption of air traffic, as aircraft movements were slowed or temporarily halted for safety checks. As visibility fluctuated and crosswinds picked up, airlines were forced to space out departures and arrivals more cautiously than usual.

Operational data collated by flight-tracking platforms and local reports suggest that the number of delayed flights at Indira Gandhi International Airport climbed past the 500 mark over the course of the weather event, affecting both domestic and international services. Many departures left Delhi hours behind schedule, while inbound flights were held in airborne holding patterns or diverted to alternate airports when conditions briefly worsened.

Passengers described crowded terminals, long waiting times at security and check-in, and difficulty rebooking missed connections to smaller cities. With aircraft and crew out of position, knock-on delays spread well beyond Delhi, contributing to late running on routes across northern and central India even after the heaviest showers had eased.

Airport operations also had to contend with surface-level challenges such as waterlogging on access roads, slower turnaround of ground support equipment and temporary congestion on aircraft stands, all of which complicated efforts to bring schedules back on track quickly.

Why heavy rain and hail hit flight schedules so hard

Weather-related disruptions are a familiar issue for Delhi’s busy hub, but intense convective storms featuring lightning, strong gusts and hail can be particularly disruptive. According to publicly available aviation safety guidance, heavy rain reduces visibility, affects braking performance on wet runways and can interfere with the safe operation of ground vehicles around aircraft.

Hail and strong updraughts add another layer of risk. Aircraft approaching or departing through active storm cells may be exposed to sudden wind shear, turbulence and ice impacts, requiring pilots to delay take-off, divert around storms or hold at a safe distance until conditions improve. Even short suspensions of operations during peak hours can create substantial backlogs at an airport that routinely handles more than a thousand movements a day in the summer season.

Once flights are delayed on the ground, turnaround times tend to stretch as catering, refuelling and baggage handling crews work in challenging conditions. If aircraft and crew exceed legal duty-time limits because of prolonged waiting, airlines must reschedule rotations or cancel services outright, extending the impact of a single storm across the day and sometimes into the following one.

Recent compilations of global weather incidents shared by climate and aviation watchers have highlighted how increasingly volatile pre-monsoon patterns, including sudden downpours and hailstorms around Delhi, have already caused multiple episodes of disruption this year, reinforcing concerns about the resilience of airport operations during rapidly changing weather.

Will Delhi see more flight disruptions today?

Forecasts from the India Meteorological Department and other publicly accessible weather models for Saturday, 9 May 2026, point to a continued spell of active pre-monsoon conditions over parts of north India. Outlooks for Delhi-NCR indicate the possibility of more clouds, intermittent rain or thunderstorms in and around the region, although the exact timing and intensity remain uncertain.

Current guidance suggests that while a repeat of the most severe hail-bearing cells is not guaranteed, the atmosphere remains unstable enough for fresh development of thunderstorms, particularly in the late afternoon and evening. If strong convective activity redevelops close to the airport’s approach paths, further short-notice restrictions on take-offs and landings cannot be ruled out.

Publicly available information from aviation planning tools shows that airlines and airport operators typically factor such forecasts into their schedules by building in modest buffers, but dense peak-hour waves leave limited room to absorb fresh delays. Travellers flying into or out of Delhi today therefore face an elevated risk of schedule changes compared with a typical clear-weather day.

Travel analysts caution that even if Delhi itself avoids the most intense storms, adverse conditions at other airports feeding traffic into the capital can still trigger indirect disruptions. Weather-related ground holds or diversions at regional hubs often cascade back into delayed arrivals at Indira Gandhi International Airport, compounding local congestion.

What passengers flying through Delhi should expect

For passengers with departures scheduled from Delhi on 9 May, publicly available updates from airlines and airport channels emphasise the importance of monitoring flight status closely, especially in the hours leading up to travel. Same-day schedule changes, gate swaps and revised departure times are more likely when storm cells are moving through the region.

Travel experts recommend arriving at the airport with additional time to spare, as queues at check-in, security and boarding can lengthen quickly when multiple flights are rescheduled around the same time. Those with tight domestic-to-international or international-to-domestic connections may wish to explore earlier feeder flights where possible, given the heightened risk of knock-on delays.

Passengers connecting through Delhi from smaller cities may also encounter aircraft changes or rebookings if inbound flights are held or diverted due to localised thunderstorms along their route. In such situations, airlines generally prioritise safety and regulatory limits, which can result in last-minute adjustments that ripple through the day’s operations.

Given the potential for further weather instability over the weekend, experienced flyers often advise packing essential medications, a change of clothes and basic necessities in cabin baggage, in case extended waits or overnight stays become unavoidable during disruption-heavy periods.

Outlook for the coming days and impact on summer travel

Meteorological outlooks for the coming days suggest that the broader north Indian region, including Delhi, will remain under the influence of pre-monsoon systems capable of producing additional rounds of showers, thunderstorms and gusty winds. While not every day will bring disruptive conditions over the airport itself, the pattern raises the likelihood of further episodes of weather-related delays during May.

This comes at a time when India’s domestic aviation market is entering one of its busiest travel windows, with school holidays, pilgrimages and summer tourism driving high passenger loads. High demand limits the availability of spare seats, making it more complicated for travellers to secure quick rebookings when flights are cancelled or severely delayed.

Industry observers note that in recent years Delhi has faced disruption from a range of weather extremes, from dense winter fog to unseasonal spring storms and heavy downpours. The latest wave of rain and hail, with its tally of more than 500 delayed flights, adds to growing pressure on airlines and airport operators to refine their contingency planning, invest in rapid recovery measures and communicate more proactively with travellers when schedules unravel.

For now, the immediate advice for anyone flying through the national capital today is to stay alert to evolving forecasts and real-time airline updates, build extra flexibility into itineraries and be prepared for the possibility that further bursts of unstable weather could again put Delhi’s air traffic to the test.
