DFW International Airport officials plan to raise the fees for drivers who cut through the airport to save time.

The rate for pass-through commuters spending less than 8 minutes on airport property would increase to $6 starting Oct. 1, up from $4.

"This is to discourage drivers that cut through the airport to save time," DFW Airport CFO Chris Poisatte said.

Poisatte said airport roads, built and maintained with airport revenues and fees from airlines, are not intended to be a toll road for frustrated commuters.

DFW International Airport's board will vote on the proposal Thursday.

Last year, about 2,500 commuters a day cut through the airport, presumably to save time during busy rush-hour congestion between communities north and south of the property.

By the airport's estimations, they make about $3.6 million a year on pass-through commuters. Raising the fee by 50% would raise another $1.8 million if the higher rates don't scare away drivers.

"The rates are increasing so DFW can continue to improve upon parking and roadway infrastructures," airport spokeswoman Cynthia Vega said.

Any vehicle that enters the airport pays a fee, whether it's locals picking up passengers, ride-share drivers or those who park there.

Drivers that stay from 0 to 8 minutes pay $4, while those on the property 8 to 30 minutes only pay $2. For those remaining on-site between 30 minutes and 2 hours, it's $3.

Those fees come from airport estimates on how long it takes to pick up and drop off passengers. Drivers on property less than 8 minutes, they presume, are only cutting through.

The price hike on pass-through drivers is the only parking and toll fee increase planned for the upcoming year.
