On November 20, 2025, Mumbai Airport will remain closed from 11 am to 5 pm due to runway maintenance. MIAL cited security and technical investigation as the reason. Airlines were allowed to change schedules by issuing NOTAM. Navi Mumbai airport will also open in December.
New Delhi. Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) will be completely closed for six hours on 20 November 2025. This decision has not been taken suddenly, but the simultaneous closure of the runway of such a busy airport raises big questions in itself. Is the reason so serious that all flights have to be stopped during the day?
CSMIA is the second busiest airport in the country.
It is noteworthy that CSMIA is the second busiest airport in the country, where about 950 flights land and take off every day. In such a situation, the shutdown from 11 am to 5 pm is creating many discussions in the minds of people.
Why will the runway be closed for six hours?
According to airport operator MIAL, this maintenance is being done keeping in mind “continued safety, runway strength and global aviation standards”. But the question is also why such huge repairs are being done at one time?
Sources say pressure was continuously increasing due to heavy traffic on runways 9/27 and 14/32. Therefore MIAL issued NOTAM and informed all the airlines in advance. This helped in re-adjusting the flight schedule.
Will your flight be canceled or rescheduled?
After NOTAM, many airlines have changed the timing of their flights. However, MIAL claims that its aim is to provide minimum hassle to passengers. Still, passengers have been advised to check their flight status in advance.
What special work is going to happen on the runway?
According to the information, in repair-
- Runway surface repair
- Lighting system inspection
- marking re-painting
- drainage check
- Technical security assessments are included.
Will Navi Mumbai airport ease the pressure?
Meanwhile, Navi Mumbai International Airport (NMIA) is also going to open from December 25. In the first phase it will handle 23 flights daily and a total of 120 ATMs. Many experts believe that after the launch of NMIA, the burden of CSMIA will reduce somewhat.
What major change is going to come in Mumbai’s aviation system?
NMIA will be operational 24×7 from February 2026, leading to a new distribution of air traffic in the Mumbai Metropolitan Region. This could provide passengers with more choices and less crowded terminals.
