IndiGo, Air India, SpiceJet and Akasa Air have issued travel advisories warning of possible flight delays as heavy monsoon rain continues to affect Delhi into Saturday, August 8, a day after the city recorded its wettest August day so far.

Friday’s rainfall — 60.4mm at Lodhi Road and 59.2mm at Safdarjung in a 24-hour window — triggered a red alert, at least nine house collapses, and 16 fallen trees across the capital, with the disruption now extending into a second day via continued flooding on South Delhi’s MB Road.

For India’s airline operators, back-to-back severe-weather days at the country’s busiest hub are effectively a live resilience test: each carrier’s advisory language — IndiGo citing ‘extended wait times,’ Air India flagging both weather and airport congestion, Akasa Air warning of road-access delays — reflects differing operational playbooks for the same event.

The pattern is also a recurring one this monsoon season, with Delhi-NCR having already seen multiple rounds of IMD alerts and airline advisories in recent weeks, suggesting airlines serving the route are building institutional muscle memory around monsoon-driven schedule disruption.

For businesses dependent on reliable Delhi connectivity — logistics firms, event organisers, and startups with distributed teams — this is a reminder that monsoon-season buffer time into travel planning isn’t optional in the NCR corridor between roughly July and September.

The IMD’s Saturday morning bulletin, issued at 9:15am, forecast continued rain over Delhi, Haryana and Chandigarh, with yellow alerts still active for Ghaziabad and Gautam Budh Nagar.

The India Meteorological Department had earlier issued a red alert for Delhi during a three-hour window on Friday morning, before downgrading to orange alerts across most of the city through the rest of the day.

At least nine houses collapsed and 16 trees fell across the capital since Thursday night, with three women requiring rescue after a tree struck their residence.
