Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) is set to carry out its yearly runway maintenance on 7 May 2026, and for a few hours, flight operations will come to a complete pause.
Both runways (Primary 09/27 and Secondary 14/32) at the airport will be closed from 11:00 AM to 5:00 PM, meaning no take-offs or landings during this time.
Why the Airport Is Closing Its Runways
This isn’t a sudden move. It’s part of the airport’s annual pre-monsoon maintenance plan.
Every year, before heavy rains hit Mumbai, the airport checks its runways to make sure they are safe and ready. Rain can affect runway grip and visibility, so this step is essential.
During this six-hour window, teams will:
- Inspect runway surfaces for damage or wear
- Carry out preventive repairs
- Check systems that help planes land safely in bad weather
The idea is simple: fix small issues now to avoid bigger problems during the monsoon.

Airlines Were Informed in Advance
Here’s the good part for travellers. Airlines weren’t caught off guard.
The airport started planning this six months ago, working closely with airlines and aviation authorities. This gave carriers enough time to:
- Adjust flight schedules
- Reschedule departures and arrivals
- Inform passengers in advance
So while there will be fewer flights during those hours, major last-minute chaos is unlikely.
What This Means for Travellers
If you’re flying to or from Mumbai on 7 May, here’s what you should keep in mind:
- Flights during the closure window may be rescheduled or shifted
- Early morning and evening flights should operate normally
- Always check your flight status before heading to the airport
A quick check with your airline can save you a wasted trip.
A Routine Exercise at One of India’s Busiest Airports
Mumbai’s airport handles a huge number of flights every day, so keeping its runways in top condition is critical.
This planned shutdown may be inconvenient for a few hours, but it plays a key role in ensuring safe, smooth operations during the monsoon season.
In short, a short pause now helps avoid bigger disruptions later.
