Chennai Airport’s proposed Terminal 5 could lift annual capacity to 55 million passengers

Chennai Airport is studying a Terminal 5 positioned between its two runways, which could add capacity for about 20 million passengers a year. Alongside the ongoing Terminal 3 expansion, the project would enlarge the long-term addressable market for airport retail, food, travel services and advertising operators, subject to approvals and detailed design.

What happened

Chennai Airport is advancing plans for Terminal 5 between its runways, potentially lifting annual passenger capacity to 55 million. A proposed 5.32-km elevated

Key facts

  • Proposed Terminal 5 could add capacity for around 20 million passengers annually
  • Total Chennai Airport capacity could reach around 55 million passengers annually after T5
  • Ongoing expansion is expected to bring capacity to around 35 million passengers annually
  • Airport estate spans 1,300 acres
  • Proposed elevated corridor length: 5.32 km
  • Runway capacity could increase from around 35 to 45-46 aircraft movements per hour

Why this matters

Consumer and travel-sector acquirers should monitor Chennai Airport’s expansion pipeline for partnership, concession and bolt-on opportunities that can capture a larger captive passenger base across retail, dining and services.

What to watch

  • Formal airport authority approval, master-plan inclusion and funding structure for Terminal 5.
  • Terminal 3 commissioning milestones, gate capacity additions and revised annual passenger-capacity guidance.
  • Passenger traffic growth versus existing terminal capacity, especially international and peak-hour demand.
  • Announcement of retail, F&B, duty-free, lounge, advertising or service concession tenders.
  • Airline route additions, international connectivity growth and changes in low-cost-carrier share.
  • Changes in airport retail policy, duty-free rules, security flows, curbside access or passenger-processing design that affect dwell time and conversion.
  • Map Chennai Airport exposure across duty-free, foodservice, lounges, forex, travel retail, advertising and last-mile travel-service operators.
  • Track current concession expiry dates and likely tender windows; expansion planning can create early positioning opportunities before additional terminal space opens.
  • Prioritize modular, fast-turn formats suited to domestic passenger growth, including quick-service food, coffee, convenience, regional products and digitally enabled ordering.
  • Assess whether incumbent operators can secure preferential expansion rights or whether new terminal development is likely to trigger competitive rebidding.
  • Model revenue using passenger mix rather than total footfall alone, separating domestic, international, departing, arriving and transit passenger spend potential.
