What to watch
- Final airline-by-airline allocation of T1 domestic flights to T2 and international flights to Navi Mumbai.
- Navi Mumbai airport opening schedule, runway and terminal capacity, and timing of commercial international operations.
- T2 security wait times, gate utilization, curbside congestion and public-transport access after the traffic shift.
- Terminal-specific passenger dwell time, retail conversion, average transaction value and F&B queue times during phased migration.
- Concession tender announcements, retail-unit handover dates and duty-free operator commitments at Navi Mumbai.
- Changes in airline schedules, slot allocations or redevelopment timing that prolong T1 operations or alter the intended traffic split.
- Reforecast terminal-level passenger volumes, dwell time and sales per passenger for T2 and Navi Mumbai from 2026 through the first 12 months after the January 2027 T1 redevelopment start.
- Prioritize capacity additions at T2 in quick-service food, coffee, convenience, charging, baggage services, forex and last-minute travel retail, where congestion-driven demand is most immediate.
- Secure or expand Navi Mumbai concessions early, with emphasis on duty free, premium F&B, beauty, lounges, ground transport and digital travel services targeted at international flyers.
- Renegotiate concession staffing, inventory replenishment, storage and minimum-guarantee terms to reflect uneven traffic ramps and transition-period volatility.
- Use airline, flight-bank and passenger-origin data to tailor assortment and operating hours by terminal rather than applying Mumbai-wide demand assumptions.
