SEATTLE (WTVR) - How would you like free parking when you visit the airport?
Travelers in Seattle have been getting free parking when they fly -- and the state says it's a mistake.
A computer error at the parking kiosks is only charging some of the credit cards that get scanned at the machines.
A Washington state auditor says that travelers have gotten $400,000 worth of free parking.
It sounds like good news. However, the auditor also says that some drivers were being overcharged.
