Airports, often operating with thin margins, have developed several strategies to generate revenue. In the United States, where most airports are publicly owned and operated, this task is essential to fund expansion initiatives and prevent cash shortfalls.
One primary revenue stream comes from airlines that pay for using airport facilities. Airports charge airlines landing fees based on aircraft size and weight. For example, San Francisco International Airport (SFO) charges approximately $8-10 per thousand pounds of maximum approved takeoff weight. Parking fees also contribute significantly to an airport's income.
Additionally, ground transportation provides another significant source of revenue. Airports charge for parking in various lots and may operate or charge rideshare services like Lyft and Uber for access to dedicated lanes. Newark Liberty International Airport (EWR) operates an AirTrain service with fees embedded in passenger tickets via NJ Transit and Amtrak.
