If you’re using ride-hailing services to get to certain Alaska airports, it could soon be a little more costly.

The state’s Department of Transportation is proposing a fee on what are known as Transportation Network Companies like Uber and Lyft. The companies would be charged $2.50 each time they pick up or drop off customers at Ted Stevens International Airport in Anchorage or the Fairbanks International Airport. It would be up to the ride-hail services whether they pass that cost on to riders.

According to Keith Day, the international airports controller for DOT, the fees are intended to add revenue for general maintenance and operations. The rate is based on similar measures implemented at other airports.

The measure would only affect international airports, which have different funding structures than other state-run airports. DOT is taking public comment through the end of the month. If passed, the new fee would take effect February first.
