Mumbai Airport shut 6 hours today for pre-monsoon runway work
Synopsis
Mumbai's Chhatrapati Shivaji Maharaj International Airport goes completely dark for six hours on 7 May — both runways shut for pre-monsoon maintenance. Airlines were notified six months ago, but passengers flying in or out of one of the world's busiest airports today face significant schedule disruptions.
Key Takeaways

Both runway 09/27 and runway 14/32 are closed, making the airport fully non-operational for six hours .

The maintenance covers airside infrastructure spread over 1,033 acres .
CSMIA has seen prior disruptions — 107 flight cancellations on 3 March and 66 cancellations on 8 March , linked to the West Asia conflict .
Flight operations at Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai will remain suspended for six hours on Thursday, 7 May, from 11 am to 5 pm IST, as both runways undergo scheduled pre-monsoon maintenance, officials confirmed. The closure renders the airport completely non-operational during the designated window.
Which Runways Are Affected
The shutdown covers runway 09/27 and runway 14/32 — the airport's only two operational runways. With both closed simultaneously, no arrivals or departures can be processed during the six-hour period. The maintenance is part of CSMIA's annual monsoon preparedness programme, designed to ensure airside safety and smooth flight movement during Mumbai's notoriously heavy rainy season.
What the Airport Operator Said
Mumbai International Airport Ltd (MIAL), which operates the 1,033-acre airside infrastructure, said the work is essential for the upkeep and long-term safety of the facility. The operator added that stakeholder consultations had begun nearly six months ago to allow airlines to adjust schedules in advance and minimise passenger inconvenience.
Point of View
Today's planned closure adds to a pattern of compressed air connectivity at a hub that has no meaningful alternate airport to absorb overflow. As monsoon season approaches, CSMIA's infrastructure resilience — and MIAL's crisis communication — will face a sterner test than a single maintenance window.
