A major international flight shift standoff has emerged between global legacy airlines and Adani-operated Mumbai International Airport Limited (MIAL). International carriers, including Emirates and Air France-KLM, are actively resisting proposed mandatory relocations from Chhatrapati Shivaji Maharaj International Airport (CSMIA) to the newly constructed Navi Mumbai International Airport (NMIA).
The conflict stems from MIAL’s strategic proposal to trim CSMIA’s annual capacity by roughly five million seats starting in 2027 to facilitate major terminal redevelopments. While domestic carriers like IndiGo and Air India Express have agreed to a phased transition of short-haul regional flights, foreign long-haul operators strongly oppose forced operational transfers.

Grandfather Slot Rights and Transit Infrastructure Gaps
In the Navi Mumbai airport international flight shift standoff, international airlines assert that unilaterally moving operations away from CSMIA violates historic grandfather slot entitlements recognised under international civil aviation frameworks. Overseas carriers maintain that historical slot access at Mumbai’s primary gateway must remain protected throughout terminal renovation phases.
Furthermore, foreign airlines point out critical infrastructure gaps connecting the two aviation hubs. Rapid high-speed transit corridors and metro links between Santacruz and Ulwe remain under construction, meaning inter-airport transfers can take up to two hours during peak traffic. Splitting operations across two distinct airports inflates ground-handling expenses, complicates interline partner connections, and disrupts premium business travel networks.

Bilateral Entitlements and Regional Capacity Realignment
The Navi Mumbai airport international flight shift standoff also intersects with bilateral flying agreements. Foreign hub operators stress that moving flights to a secondary airport without securing additional flight rights from the Ministry of Civil Aviation (MoCA) provides zero operational gain while increasing capital complexity.
Conversely, airport operators argue that utilising NMIA’s initial 20-million passenger capacity is essential to prevent severe congestion at CSMIA. To incentivise voluntary transitions, MIAL approved a variable tariff structure featuring landing fee waivers for newly launched international routes during their first operational year.
Ultimately, resolving this hub division requires a balanced regulatory approach. Therefore, aviation authorities must coordinate transit infrastructure development with clear slot protection guarantees to maintain Mumbai’s status as a premier global aviation crossroads.
