Back then I wanted to know if the plan involved any Korean airlines or airlines departing from Korea. Now due to my renewed interest I've got my answer.

MANILA (AP) — Two top al-Qaeda operatives smuggled explosive ingredients onto flights from Manila and Hong Kong in 1994 as part of a test run for a failed plot to blow up 12 U.S.-bound airliners, according to a confidential document obtained by The Associated Press.
Captured terror suspect Khalid Sheikh Mohammed's key role in the al-Qaeda plot to simultaneously bomb the commercial planes flying out of Asia — in a 1995 plan called "Project Bojinka" — was one of several admissions that he made, the U.S. Defense Department said.
Defense Department officials released a transcript of Mohammed's confessions, detailing his claims of roles in 31 terror plots worldwide, during a hearing at Guantanamo Bay prison.
"I was responsible for the planning and surveying needed to execute the Bojinka operation, which was designed to down 12 American airplanes full of passengers," the transcript quoted Mohammed as saying.
Mohammed said he personally monitored "a round-trip, Manila-to-Seoul, Pan-Am flight."

The next plan would have involved at least five Al-Qaeda operatives, including Yousef, Khan, Shah and two more unknown operatives. Starting on January 21, 1995 and ending on January 22, 1995, they would set the bombs on 11 United States-bound airliners that had stopovers all around East Asia and Southeast Asia. All of the flights had two legs. The bombs would be planted inside life jackets under seats on the first leg, when each bomber would disembark. He would then board one or two more flights and repeat. After all of the bombers planted bombs on all of the flights, each man would then catch flights to Lahore, Pakistan. The men never needed U.S. visas, as they only would have stayed on the planes on their first legs in Asia.
United States airlines had been chosen instead of Asian airlines so as to maximize the shock toward Americans. The flights targeted were listed under operatives with codenames: "Zyed", "Majbos", "Markoa", "Mirqas" and "Obaid". Obaid, who was really Abdul Hakim Murad, was to hit United flight 80, and then he was to go back to Singapore under another United flight which he would bomb.[3][5][7]
Zyed, probably Ramzi Yousef, was to hit Northwest Flight 30, a United Flight going from Taipei to Honolulu, and a United Flight going from Bangkok to Taipei to San Francisco[3][8]
The bombs would have been timed before the operatives stepped off the planes. The aircraft would have blown up over the Pacific Ocean and the South China Sea almost simultaneously. If this plan worked, several thousand would have perished, and air travel would have been shut down worldwide for days, if not weeks. The U.S. government estimated the prospective death toll to be about 4,000 if the plot had been executed.
