The 50 busiest airports in the U.S. collected more than $183 million last year from travelers using taxis, shuttle buses or other forms of ground transportation, according to Associated Press calculations from data obtained through dozens of public records requests.

Fees ranged widely from airport to airport. They were only paid — directly or indirectly — by those who used these services. Passengers picked up by friends or family generally didn’t pay the fees. And in many cases, they were split by groups traveling together, such as three fliers sharing a taxi.
