OMAHA, Neb. (AP) — An Omaha woman who is accused of selling worthless airline vouchers has pleaded not guilty to 25 federal charges.

Thirty-year-old Patricia Urbanovsky pleaded not guilty Monday in an Omaha federal court. She was indicted in February on nine counts of money laundering and 16 counts of wire fraud.

Her next court appearance is scheduled for June 15.

Urbanovsky is the owner of Creative Creations in Omaha. Authorities say she ran a scheme through her business to sell discounted airline travel vouchers, which turned out to be worthless. Authorities say the company purchased the vouchers for airline flights at a reduced rate and resold them to the public. But hundreds of customers discovered their vouchers wouldn’t be honored because the company had overbooked flights.
