On 11 December 1994, Yousef conducted a trial run of the plan by boarding Philippine Airlines Flight 434 from Manila to Tokyo, Japan, with a stopover in the Philippine city of Cebu. His identity for the flight was that of an Italian man named Armaldo Forlani. The cabin crew for this leg of the flight later told investigators that Yousef changed seats several times during the relatively short flight, with his last seat change coming after a return from the lavatory.
