According to information from Flight Radar, the plane carrying Trump's son was at Banja Luka airport this morning, just before six o'clock. He arrived in Banja Luka from Belgrade, and had come to Belgrade from Astana, where he went after visiting Banja Luka. According to his flight schedule, he departed for the capital of Kazakhstan on the afternoon of April 7th, and at 2:00 AM on April 9th, he left that city for Belgrade, where he stayed for an hour. Then, from Belgrade, he traveled to Banja Luka, where he also stayed for about an hour before heading to West Palm Beach. It is not known why Trump Jr. made stops in Banja Luka and Belgrade this morning, considering that jet fuel can be refueled at any airport. Trump Jr. spent Tuesday in Banja Luka, where he attended a panel at the Banski Dvor with politicians and farmers from the Republika Srpska.
