The owner of a Saco travel agency who took thousands of dollars from clients for trips she never booked was sentenced Monday in U.S. District Court to serve a year and half in federal prison.

Beth M. Rogers, 46, of Portland was also sentenced by Judge Nancy Torresen to serve six years of supervised release after completing her prison term and to pay nearly $209,000 in restitution.

Rogers pleaded guilty on May 17 to federal charges of mail fraud and wire fraud.

As owner of TravelWise Cruises and Tours, Rogers would book individual clients and companies with tour operators, hotels, airlines, cruise companies and other businesses, according to a prosecution document filed with the court.

“Beginning in late 2011, however, Rogers began taking client money without making travel reservations for those clients. She instead used the clients’ money to pay for the travel of other TravelWise clients. Rogers continued to misapply client money in this fashion until mid-2012, when her scheme was discovered,” Assistant U.S. Attorney Craig Wolff said in the document.

In some cases, in which clients paid Rogers by mail or in person, she deposited the money in a bank account but failed to book the travel, Wolff wrote.

In other cases, Rogers used client credit card account numbers to pay for a second client’s travel without the first client’s permission, according to the prosecution document.

Court records indicate Rogers defrauded 55 different victims, many of whom were retired and on a fixed income.
