Flight operations at Chhatrapati Shivaji Maharaj International Airport (CSMIA) in Mumbai will be suspended for six hours on 17 October due to scheduled maintenance work. Both the main runway, RWY 09/27, and the secondary runway, RWY 14/32, will be out of service from 11:00 to 17:00 hours that day. As a result, flight schedules for arrivals and departures at Mumbai Airport will be adjusted.


Airlines and related agencies were notified six months in advance to minimise the impact on flight operations. The airport typically halts air traffic for runway maintenance post-monsoon.
