More than 550 flights faced delays at IGI Airport on Friday after a red alert rain spell hit Delhi.

Palam saw the city’s highest rainfall total at 75.6mm, with Naraina, Janakpuri, Lodhi Road and Safdarjung also recording heavy downpours.

Ten flights were diverted during the disruption, with five sent to Jaipur, four to Lucknow, and one each to Ahmedabad and Chandigarh.

Flooding around Terminal 3 and the Vasant Kunj underpass slowed access to the airport, adding to the day’s travel woes.

IndiGo and Air India issued advisories urging passengers to check flight status before heading out and to allow for slower road travel.

IndiGo and Air India both issued advisories asking passengers to check their flight status before leaving for the airport and to allow extra time given slow road movement.

The IMD’s red alert signals the most severe warning level, reserved for extremely heavy rainfall expected to cause significant disruption to daily life and infrastructure.

Delhi has faced repeated bouts of airport disruption this monsoon season, with heavy rain periodically triggering diversions and delays at IGI in recent weeks.

IGI Airport is one of the busiest in the country, typically handling well over a thousand flight movements a day, meaning disruptions there tend to cascade across the wider domestic network.

Passengers travelling to and from Delhi in the coming days have been advised to monitor airline communications closely given the ongoing unsettled weather pattern.

Palam recorded the highest rainfall in Delhi at 75.6mm by late afternoon, while Naraina registered 54mm, Janakpuri 48.5mm, Lodhi Road 34.6mm and Safdarjung 32.6mm.

Five aircraft were redirected to Jaipur, four to Lucknow, and one each to Ahmedabad and Chandigarh as the airport struggled to handle the volume of traffic during the downpour.

Air India’s Delhi-Manila route is getting a bigger aircraft, with the airline set to deploy a 256-seat Boeing 787 Dreamliner from October 25, 2026, in place of the current 188-seat Airbus A321.

The daily service has grown steadily since it launched in October 2025 with just five weekly flights, a ramp-up that reflects sustained travel demand between the two countries.

Load factors on the Manila-Delhi sector have twice touched the low 80s, according to aviation analyst Ameya Joshi, a figure that helps explain Air India’s decision to add capacity now.

The move comes as competition builds on the route, with IndiGo applying for Philippine regulatory approval to begin its own flights to Manila and Cebu.

Philippine Airlines is separately preparing to launch Delhi and Mumbai services during the winter schedule, drawing on a bilateral agreement that permits up to 28 weekly flights between the two countries’ key cities.

Indian arrivals in the Philippines rose 43% year-on-year in the first half of 2026, with visa-free travel access for Indian passport holders cited as a major factor behind the growth.

Indian arrivals in the Philippines rose 43% year-on-year in the first half of 2026, with more than 60,000 Indian travellers visiting the country in that period alone.

Visa-free access for Indian passport holders travelling to the Philippines has been cited by industry watchers as a key driver behind the surge in leisure and business travel between the two countries.

India and the Philippines elevated their bilateral relationship to a strategic partnership in 2025, a diplomatic shift that has coincided with expanded airline interest in connecting the two markets.

IndiGo, which already dominates India’s domestic skies with roughly two-thirds market share, has been steadily building out its international network beyond South Asia and the Gulf in recent quarters.

The government is weighing a proposal to make drug testing mandatory for every pilot once a year, up from the current 10% sampling of the overall pilot network.

Civil Aviation Minister Ram Mohan Naidu said, “Right now, the rule says 10 per cent across the overall pilot network,” while confirming that the DGCA is in discussions with stakeholders on expanding the testing regime.

The proposal follows the August 4 Air India flight AI2379 incident, when the Phuket-Delhi Airbus A320 lost around 300 feet of altitude after a hydraulic failure, injuring 17 people onboard before landing safely in Delhi.

The incident triggered concerns after a subsequent confirmatory drug test of the pilot-in-command reportedly returned positive for marijuana.

Air India subsequently expanded drug screening across its pilot workforce, with two more pilots later found to have failed preliminary drug tests and being removed from flight duties as a precaution.

Around 400 pilots have so far been screened as part of the airline’s expanded internal testing exercise following the incident.

Naidu said the discussions on strengthening testing rules are separate from the ongoing investigation into the Air India incident itself, which continues under separate review.

India’s aviation sector has been expanding rapidly in recent years, adding pressure on regulators to scale up safety and compliance infrastructure, including staffing and laboratory capacity for expanded testing regimes.

The Federation of Indian Pilots has urged consideration of oral-fluid testing as a complementary methodology within the existing regulatory framework, to help expand testing capacity as India’s aviation sector grows.
