Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai will suspend all flight operations for six hours today, from 11 AM to 5 PM, due to essential maintenance on both its primary and secondary runways. This annual pre-monsoon maintenance aims to ensure the safety and longevity of the airport's airside infrastructure in preparation for the upcoming rainy season. The maintenance covers 1,033 acres and involves checking runway conditions, repairing wear and tear, and implementing preventive measures for safer landings and take-offs. The airport operator has emphasized that stakeholder consultations were conducted six months in advance, allowing airlines to adjust their schedules accordingly. Similar maintenance activities were performed twice last year, with both runways temporarily closed for six hours each time.
