Passengers are frustrated after tour operator Go Travel announced that it won't be following through on its plan to operate direct flights from St. John's to London, England later this year.

St. John's university student Sarah Stoodley purchased a ticket for a Go Travel flight to the U.K. (CBC)Sarah Stoodley, a university student in St. John's with a two-year work visa for England, had purchased a ticket from Go Travel.

"I'm very frustrated because now what was costing me $350 - whether I get that money back I'm not sure - now it's going to cost me almost $2,000 because I have to book another flight," she said.

Stoodley said in the future she'd be cautious in booking any sort of charter flight.

Go Travel South announced its termination on its website Wednesday. "Please do not show up to the airport for your flights as they will not be departing," the message read. The company told customers it will not respond to any emails and advised them to contact their credit-card providers for a refund.

Meanwhile, Flair Air Ltd., the airline that supplied Go Travel South with its flights, posted a message on its website saying it would fulfill its obligations and fly Canadians already away on vacation back to Canada.

Steve Outerbridge, who owns Carlson Wagonlit Harvey's Travel agency in St. John's, said his agents decided not to book flights involving Go Travel because of the company's past history.

The low-fare Zoom airline folded a year and a half ago.

In 2008, Go Travel tried to start direct flights from Newfoundland to the United Kingdom, but had to refund passengers because the airline it was using did not have a license to fly the route.

Last November, Go Travel contracted another airline which it said had the proper documentation and started taking bookings for flights starting in June.

Owner Hugh Boyle blamed the latest problems on the company hired to process credit card payments for Go Travel. He says that firm filed for bankruptcy recently while still owing his company $1 million.
