The Better Business Bureau of Southern Arizona has issued a timeshare scam warning for its citizens.

BBB says that some scammers send out branded Southwest mailers in Tucson, claiming that the recipients have won round-trip airfares from the airline.

According to a BBB press release: “Consumers who call the number on the back of the card are told that in order to claim the airline vouchers they must own a timeshare, and they must attend a seminar this Saturday, Sunday or Monday at the Hilton Tucson East, located at 7600 E Broadway Blvd, in Tucson.”

BBB explained that Southwest Airlines is not affiliated with the scam. BBB added: “In BBB's experience "airline vouchers" given as incentives for attending presentations often include hidden fees and a numerous blackout dates for travel.”

In the last two years, there has been an unprecedented increase in timeshare scams across the country. To protect yourself from these scams, be wary of companies you work with. If possible, double check their name with the nearest BBB in your area.
