Flying to Mumbai
Chhatrapati Shivaji Maharaj International Airport (BOM / VABB) · Last reviewed: April 2026
Airport Overview
Chhatrapati Shivaji Maharaj International Airport (IATA: BOM, ICAO: VABB) is India's busiest airport by passenger traffic, according to Airports Authority of India (AAI) published data. Located within the city of Mumbai on the western coast, the airport operates within the Mumbai FIR (VABF), managed by AAI.
BOM handled over 55 million passengers in 2025 according to AAI statistics, serving as a hub for Air India, IndiGo, and numerous international carriers. The airport operates two intersecting runways (09/27, 3,660 m and 14/32, 2,926 m) with a cross-runway configuration that creates documented capacity constraints. According to IATA, BOM is one of the busiest single-site airports globally for its runway infrastructure.
The Navi Mumbai International Airport (NMIA), currently under construction, is documented in published AAI plans as supplementary capacity for the Mumbai metropolitan area. According to government announcements, initial operations are projected for the late 2020s.
Common Routes & FIRs Crossed
Mumbai's position on India's west coast places it along major intercontinental corridors. According to Eurocontrol and published flight data:
From Europe: Flights typically cross Turkish (LTAA) or Egyptian (HECC) FIRs, then transit through Gulf-area FIRs (OMAE Emirates, OIIX Tehran, or OOMM Muscat) before entering VABF from the west. The closure of Pakistani airspace (OPKR Karachi FIR) to certain carriers has affected routing options, requiring some operators to take more southerly paths via the Arabian Sea.
From North America: US-Mumbai flights typically route eastward via the Atlantic and European/Middle Eastern airspace, or westward via the Pacific with a stop. Direct eastbound routings cross OMAE or OIIX before entering VABF.
From Southeast Asia: Routes cross the Bay of Bengal, transiting Chennai FIR (VOMF) or entering VABF directly from the east over central India.
According to published Eurocontrol and IATA data, Pakistan's airspace restrictions have been a significant factor for Europe-Mumbai routing. With the OPKR (Karachi) FIR restricted for certain carriers, some flights route via the Muscat FIR (OOMM) and approach Mumbai from the southwest, adding documented flight time.
Airspace Conditions
The VABF FIR is not subject to EASA or FAA airspace restrictions, according to published advisory databases. AAI manages extensive ATC infrastructure including radar coverage across the western Indian airspace. According to ICAO assessments, India has implemented modern surveillance and communication systems across its major FIRs.
India's aviation sector is experiencing significant traffic growth, as documented in IATA and DGCA (Directorate General of Civil Aviation) reports. VABF is one of the fastest-growing FIRs globally by movement count. Published AAI data indicates controller workload has increased correspondingly, with modernization programs underway to manage the capacity demands.
Monsoon season (June-September) significantly affects Mumbai operations. According to AAI published data, BOM experiences periodic runway closures during heavy monsoon rainfall, with documented visibility limitations and waterlogging on airport surfaces. Airlines operating to Mumbai during monsoon season file alternates including Delhi (VIDP), Hyderabad (VOHS), and Ahmedabad (VAAH).
GPS interference has not been widely reported in the VABF FIR, unlike some neighboring Middle Eastern airspace. ICAO documentation indicates standard navigation infrastructure performance in the Mumbai terminal area.
What to Check Before Booking
Current NOTAMs for the VABF FIR and en-route FIRs, particularly Pakistan (OPKR) status for European routings
Monsoon season weather forecasts (June-September) and airline rebooking policies for weather disruptions
Peak-hour congestion at BOM (limited runway capacity may cause ground delays)
Airline routing for your specific origin to understand potential flight time impacts from airspace restrictions
Travel insurance coverage terms for monsoon-related delays
