Mumbai Airport to Close Runways from 11 AM to 5 PM on November 20: Discover the Reason

Flight operations at Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) will be entirely suspended for six hours on November 20, as the airport carries out its annual post-monsoon runway maintenance.

Airport officials mentioned that a required NOTAM (Notice to Airmen) was issued six months ahead, giving airlines and other stakeholders ample time to adjust their schedules in response to the closure.

During the maintenance period, specialized engineering and airside teams will perform thorough inspections of the runway surfaces, focusing on both micro and macro structural elements that gradually deteriorate due to frequent aircraft operations.
