Officials at the St. Louis Lambert International Airport are reporting that during the first three months of Uber and Lyft being allowed to pick up and drop off passengers, revenue from other ground transportation increased by about 1%, according to the St. Louis Post-Dispatch.

Airport Director Rhonda Hamm-Niebruegge told the news outlet that revenue from parking lots, garages, car rental firms, taxicabs, and vans accounted for $12.1 million during the months of September, October, and November.

Revenue from parking and car rentals increased by 0.4% and 7.2%, respectively. Contrastingly, revenue from shared-use vans decreased by 15.3% and taxi pickups dropped by 19.5%, which cut into the airport’s per-trip taxi fees.

However, Hamm-Niebruegge reportedly told the airport commission that with new ride-hailing fees, the airport’s share of ground transportation revenue was $607,000 higher than the same three-month period in 2016.
