International airlines are being asked to shift one-third of their operations from Mumbai's Terminal 2 to Navi Mumbai starting October 1, 2026, according to reports. The proposal includes reducing 265 of Terminal 2's 770 weekly international departure slots starting October 26, 2026. This would affect 46 carriers, including IndiGo, Air India, Emirates and Etihad Airways.
The International Air Transport Association (IATA) has opposed the proposal, calling it a 'forced relocation' without collaborative consultation. The initial plan involved a 33% reduction in Terminal 2 capacity, which was later revised after airline pushback. The Ministry of Civil Aviation has directed stakeholders to create a mutually agreeable transition plan.
Maharashtra Chief Minister Devendra Fadnavis proposed a phased redevelopment of Terminal 1 to avoid flight disruptions. MIAL plans to temporarily shift flights serving 14 international destinations to Navi Mumbai starting March 2027, claiming the move will minimize passenger inconvenience during Terminal 1B redevelopment. The fully redeveloped Terminal 1 is targeted to reopen by December 2030.
Adani Airport Holdings claims Terminal 1 requires redevelopment due to structural safety concerns. Gulf airlines have sought clarity from the Ministry of Civil Aviation on whether MIAL's proposal has official approval.
The Airline Operators Committee (AOC) Mumbai urged the Ministry to step in and safeguard historical flight slots. The move has been opposed by airlines due to concerns over operational constraints and flight disruptions.
