What happened

Delhi International Airport Limited (DIAL) · DIAL’s planned Delhi airport expansion includes an inter-terminal Air Train, Terminal 4 after 2030 and Aerocity-led

Key facts

  • 2026-2036 master plan
  • annual capacity from 105 million to 140 million passengers
  • Air Train spanning 9 kilometres
  • international capacity from 20 million to 30 million passengers
  • total capacity to reach 125 million by 2029-30
  • Terminal 2 operational until at least 2030

Why this matters

Brands should assess partnerships, concessions and location pipelines across Terminal 4 and Aerocity now, before the airport’s next wave of retail inventory becomes contested.

What to watch

  • Formal approval and funding timetable for the 2026-36 master plan
  • Air Train route, station locations, fare structure and construction start date
  • Terminal 4 design, retail GLA, concession tender schedule and opening target
  • Passenger mix changes: domestic versus international, transfer traffic and low-cost carrier share
  • Aerocity hotel keys, office absorption, convention/event capacity and new commercial leasing
  • Changes in security, landside access, metro connectivity, parking and curbside policy
  • Airport concession fee structures, minimum guarantees and duty-free/F&B tender outcomes
  • Secure long-duration Aerocity sites near prospective Air Train stations, prioritising all-day F&B, convenience, pharmacy, luggage, telecom and quick-service formats.
  • Build airport-specific omnichannel offers: pre-order, flight-linked collection, hotel delivery, baggage-friendly packaging and multilingual payment options.
  • Target employee and recurring-traveller demand with subscriptions, loyalty partnerships, late-night trading and value-led meal propositions.
  • Model concession exposure carefully: prioritise high-throughput locations and flexible lease structures ahead of Terminal 4 tender activity.
  • Develop formats that can trade across terminals, Aerocity hotels and offices, using shared kitchens, inventory pools and common loyalty data.
