Philippine Airlines (PR) Flight PR102 from Manila (MNL) to Los Angeles (LAX) was diverted to Tokyo Haneda Airport (HND) after smoke was reported in the cabin of the Boeing 777 aircraft.
All 355 passengers and crew were unharmed after the April 9, 2025, incident. Philippine Transportation Secretary Vince Dizon confirmed the aircraft landed safely in Japan, and investigations into the cause of the smoke began immediately.
Emergency Diversion and Safety Response
The Boeing 777 operating Philippine Airlines Flight PR102 developed smoke in the cabin during its long-haul journey from Manila to Los Angeles.
Once the issue was detected, the cockpit crew initiated emergency procedures and diverted to Tokyo Haneda, the nearest major airport capable of handling a wide-body aircraft.
The decision emphasized the airline’s adherence to international safety protocols, where crew training and quick action play a critical role in minimizing risks.
Passengers remained onboard for several hours after landing while Japanese authorities and airline officials ensured the cabin was safe for disembarkation. To reduce smoke levels, ground staff and flight crew opened the aircraft doors for ventilation before passengers were moved off the plane.
Philippine Airlines later confirmed that the smoke originated from one of the Boeing 777’s air conditioning units. While no fire was reported, the malfunction required immediate diversion as a precautionary measure.
Technical teams in Japan began inspections of the affected unit to determine the root cause and necessary repairs.
The airline assured passengers that safety remains its top priority and stated that it is working closely with aviation regulators to ensure the aircraft is cleared for safe operation before returning to service.
