Senator Flávio Bolsonaro (PL) reportedly hired four private jets to build alternative routes for leaving Brazil for the United States, according to a report by the Argentine newspaper Clarín, summarized by UOL. The information comes from the newspaper and is not independently confirmed in the text.
According to Clarín, the family had rented a plane in Brasília to reach the Argentine border, but the aircraft's owner backed out after it became public that Bolsonaro was not supposed to leave the country. The trip was then made overland: six vehicles reportedly left the family's home in sequence to make any monitoring harder.
The paper says the departure was prepared with a sequence of flights and possible decoys. An Argentine Gulfstream IV reportedly flew from San Fernando to Puerto Iguazú on Monday night and waited until early Wednesday, when the family used it. A Learjet 45 landed there on Tuesday and returned to Buenos Aires hours later, which Clarín sees as a diversion. Two US-registered aircraft also appear in route records to Posadas, and at least one reportedly filed a misleading flight plan and diverted to Asunción, Paraguay.
Clarín also maintains that the US took part: agents linked to the State Department or an international agency reportedly coordinated immigration and customs procedures and kept the local airport police out of the area, while Argentine employees were removed. A white car reportedly served as a distraction near takeoff.
Finally, the paper says Javier Milei's government gave operational support, and that the Argentine president reportedly sent adviser Santiago Caputo confidentially to Misiones. The UOL text includes no responses from Flávio Bolsonaro, the governments mentioned or the PL to the claims.
