Cuban dissident blogger Yoani Sanchez is setting out on a three-month, dozen-nation world tour after a new law eased travel restrictions on islanders last month.

Sanchez says via Twitter that she successfully made it past the migratory checkpoint at Havana's international airport, and all that's left is to get on the plane.

She's heading first to Brazil with a layover in Panama, where she tweets she's excited to try out the airport's free Wi-Fi.

Sanchez says Cuba has denied her permission to travel about 20 times in recent years. But the exit permit requirement ended with the government's travel reform in January, and Cubans now only need a passport to leave the country.

She said Sunday that she will be away from Cuba for about three months.
