William Potts tells The Associated Press his travel documents are all set and he is booked on a charter flight from Havana to Miami early today.
He says he looks forward to getting "closure" by facing charges against him back home.
Potts hijacked an airplane and flew to the Communist-run island in 1984, expecting that Cuba would offer him guerrilla training. Instead Cuban authorities convicted him of air piracy and imprisoned him for more than 13 years.
