Saif al-Islam can be seen with a thick black beard and wearing traditional robes on a plane to Zintan.
Colonel Gaddafi's son Saif al-Islam has been captured, Libyan officials say.
He was seized by fighters near the southern town of Obari and flown to the city of Zintan in the north. Saif al-Islam told a journalist he was well.
The former leader's son is the last key member of the Gaddafi family to be captured or killed.
Saif al-Islam, 39, is wanted by the International Criminal Court (ICC) for alleged crimes against humanity during the uprising against his father.
A militia force allied to the ruling National Transitional Council (NTC) said he had been captured in the desert about 50km (30 miles) west of Obari, and taken to their base in Zintan in the north.
A commander of the Zintan militia, Wisam Dughaly, said Saif al-Islam had been captured along with several aides as they tried to smuggle him out to neighbouring Niger.
Fighters said they were taken without a shot being fired.
"At the beginning he was very scared. He thought we would kill him," one of his captors, named as Ahmed Ammar, told Reuters news agency. (BBC)
