A sandwich costs more airside than it does two miles away, and the gap is larger than rent alone explains. Several features of operating inside a terminal compound the cost.
Space is let by the airport, not the market
Terminal concessions are awarded through leasing arrangements with the airport operator, often involving a share of sales alongside a base rent.
That structure means a busy outlet pays more in absolute terms as it sells more, which changes pricing incentives compared with a fixed street lease.
Some airports apply reference pricing arrangements tied to prices at comparable locations off the field, which is why terminal menus in different cities vary in how far they diverge.
Everything arrives through security
Deliveries into the secure zone are screened and scheduled, frequently overnight, and cannot simply be topped up when a busy morning empties the display case.
Waste and packaging leave the same way. The logistics chain is longer, slower and less forgiving of demand that deviates from forecast.
Outlets therefore carry more stock than a comparable street location, which raises both storage cost and spoilage.
Staffing is harder than the wage suggests
Employees need background checks and credentials to work airside, and they queue through screening at every shift, which lengthens the effective working day.
Shifts begin before dawn to serve the morning departure wave, and public transport at those hours is limited, narrowing the pool of people who can take the job.
Higher turnover and longer recruitment lead times add cost that never appears on a menu but shapes it.
Demand is peaky and time-pressed
Customers arrive in waves tied to departures and leave when boarding is called, so an outlet must be staffed for a peak that may last ninety minutes.
Table turnover is fast, average spend is constrained by time rather than appetite, and much of the day the seats sit empty while the staffing and rent continue regardless.
Outlets respond by shortening menus and moving toward items that can be assembled quickly, since a dish that takes twenty minutes cannot be sold to someone with thirty before boarding.
Location within the terminal matters
An outlet beside a busy gate cluster trades differently from one before security or at the end of a quiet pier, and lease terms reflect that.
Passengers routinely find the same brand priced differently in two concourses of one airport, which usually reflects the lease and the footfall rather than the food.
