Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) will go completely silent on Thursday, May 7 — no takeoffs, no landings, nothing. Both the primary runway 09/27 and the secondary runway 14/32
will be shut from 11:00 AM to 5:00 PM for intensive pre-monsoon maintenance, making this one of the most significant planned disruptions at the city’s only major airport. If you have a flight tomorrow, read this before you leave home.
Mumbai International Airport Ltd (MIAL) coordinated this closure with airlines and aviation authorities six months in advance, so most carriers have already reshuffled their schedules. Still, hundreds of passengers across domestic and international routes will feel the impact through cancellations, delays, and rerouting.
Why Is This Even Happening?
The annual pre-monsoon maintenance is essential to keep CSMIA’s expansive 1,033-acre airside in top shape, with a special team checking runway surfaces for wear and tear. Mumbai’s monsoon is notoriously brutal — think relentless rain, waterlogging, and high humidity — and the runways need to be in peak condition before the season hits.
Will My Flight Be Cancelled?
Very possibly, if it is scheduled between 11 AM and 5 PM. Check your airline app or the CSMIA website right now for your flight status. Airlines may reroute flights through nearby airports, including Pune, Ahmedabad, and Goa, or offer transfers via Delhi, Bengaluru, or Chennai.
What Should I Do If My Flight Is Affected?
Contact your airline immediately for rebooking or refund options. If your flight is before 11 AM or after 5 PM, you are likely fine — but build extra buffer time anyway, as the ripple effect of a six-hour halt on an airport handling over 1,000 daily movements can stretch delays well into the evening.
One Last Thing
This closure comes after CSMIA had already cancelled over 170 movements in March due to West Asia airspace disruptions — so the airport has had a rough spring. Tomorrow’s shutdown is planned and necessary, but preparation is entirely in your hands. Check, confirm, and leave early.
