Bilateral Air Services Agreement

Imagine two countries agreeing, government to government, on exactly how many trucks each country's transport companies are allowed to drive across their shared border every week, a cap neither country's individual trucking companies can simply exceed no matter how much cargo they have to move. A Bilateral Air Services Agreement sets almost exactly this kind of government-negotiated cap for international air travel between two countries.

A Bilateral Air Services Agreement, BASA, is a treaty negotiated directly between two national governments, not between individual airlines, that establishes traffic rights, essentially how many flights, or how much total seat capacity, airlines from each country are permitted to operate between the two countries. No airline, however large or well-resourced, can simply add unlimited flights to a foreign country beyond what its own government has negotiated the right to operate.

This creates a genuine strategic layer above ordinary airline competition, an Indian carrier wanting to expand service to a specific country is fundamentally constrained by how much capacity India's government has negotiated in that country's BASA, regardless of the airline's own commercial ambition or aircraft availability. Renegotiating a BASA to expand available capacity is a government-to-government diplomatic and economic negotiation, not a decision any single airline controls.

This is exactly why Indian airlines have periodically pushed the government to renegotiate BASA terms with specific countries, particularly Gulf nations where demand for India-linked travel is exceptionally high, arguing that existing capacity caps constrain growth opportunities their own aircraft and commercial plans could otherwise capture, a recurring point of airline industry lobbying distinct from any purely commercial competitive question.

Whenever an Indian carrier's international expansion to a specific country appears to stall despite clear demand and available aircraft, a capacity-constrained Bilateral Air Services Agreement is very often the actual limiting factor, a diplomatic ceiling sitting above whatever commercial ambition any individual airline might otherwise have for that specific international market.
