Restaurants operating inside airports pay as much as 30% of their sales in rent, according to a report from Asia Economic Daily — a occupancy burden that largely explains why a meal at the terminal costs far more than the same item off-airport, and why operators pass that cost directly to passengers.

The figure reframes a common traveler complaint as a straightforward unit-economics problem. In a conventional street-level location, rent typically runs in the low-to-mid teens as a percentage of sales for a well-run restaurant. An airport concession paying up to 30% is carrying an occupancy load that can be two to three times heavier before it buys a single ingredient or schedules a single shift.

The math constrains everything downstream. A foodservice operation targeting a 10-15% operating margin in a normal site has to recover an extra 15 or more points of rent somewhere. The available levers are limited: raise menu prices, engineer the menu toward higher-margin items, cut portion costs through sourcing, or run leaner labor. At an airport, where customers are captive, time-constrained and price-insensitive relative to a missed flight, the pricing lever is the one that reliably works.

That is the mechanism behind the terminal premium. The passenger buying a $18 sandwich is not paying for extravagance in the kitchen; they are absorbing a rent structure in which the airport, as landlord, captures up to nearly a third of the concessionaire's top line. Airports, in turn, treat food and beverage as a revenue line that supports operations — which is why concession terms are set the way they are in the first place.

The structure also shapes who can afford to play. A 30%-of-sales rent burden demands high volume, standardized operations and pricing power — conditions that favor large chains and experienced concession operators over independent operators. It is one reason airport dining skews toward recognizable brands: the brand's throughput and supply-chain efficiency are what make the economics clear at that rent level.

For operators evaluating an airport deal, the reported figure is a caution against applying street-level benchmarks to terminal locations. A rent percentage that would signal a failing restaurant on Main Street can be the standard cost of doing business at a gate, provided the location's passenger traffic supports the volume the contract requires. The question is not whether 30% is high in absolute terms, but whether projected sales per square foot clear that hurdle with margin left over.

For passengers, the practical takeaway is that the price gap is structural, not opportunistic. Operators are not padding checks beyond what their cost base forces; they are transmitting landlord economics to the tray table. As airports continue to lean on non-aviation revenue to fund operations, terminal concessions are likely to remain expensive real estate — and travelers should expect the cost of eating at the gate to stay elevated in step.
