Air travel across the country slowed to a crawl on Saturday as Philippine Airlines (PAL) and Cebu Pacific carried out sweeping flight cancellations in response to a global technical alert affecting Airbus A320 and A321 aircraft, leaving thousands of passengers scrambling to rebook weekend trips.
The mass disruption came after Airbus ordered airlines worldwide to immediately update software on certain A320 family jets, following an incident in October involving a JetBlue flight where solar radiation was found to potentially corrupt flight control data.
The European manufacturer said the issue, traced to the aircraft’s Elevator and Aileron Computer, requires urgent precautionary action, with updates taking several hours per aircraft and hundreds of planes possibly needing weeks to fully resolve.
By dawn, PAL confirmed that select Manila flights to Puerto Princesa, Cebu, Davao, Tacloban, Caticlan, Iloilo, Tagbilaran, and Bacolod would not operate, noting that affected passengers may rebook, seek refunds, or convert their tickets into travel credits. The airline said its operations center had activated contingency plans but emphasized that safety advisories of this scale require immediate compliance.
Cebu Pacific followed with an even longer list, halting operations on domestic routes connecting Manila, Cebu, Davao, Iloilo, Tacloban, Legazpi, Roxas, Bacolod, Zamboanga, Tuguegarao, Butuan, Pagadian, Bohol, Dumaguete, Cagayan de Oro, General Santos, and Clark.
The carrier said its engineering teams were working “around the clock” to apply the required system patch and urged travelers to monitor flight status updates before heading to the airport. For passengers booked from November 29 to December 1, the airline is offering free rebooking and travel fund conversion.
The joint total of grounded flights reached 78 by early morning, though officials warned that the number could rise depending on how quickly airlines complete the mandatory software rollout. Aviation sources said that while the advisory affects thousands of A320-series aircraft globally, the high density of domestic routes in the Philippines means even a handful of grounded jets can cascade into widespread disruptions.
The technical alert has prompted renewed discussion on the vulnerability of modern aviation systems to extreme solar activity. Airbus said the October malfunction involving a U.S.-based jet was an anomaly, but the investigation concluded that precaution was necessary, given the intensity of solar radiation spikes recorded this year. Airlines worldwide have begun pulling affected jets for software updates, although Airbus has acknowledged that a subset of aircraft may require more extensive corrective work.
The cancellations also hit at a time when airports nationwide are entering the early wave of holiday travel, prompting calls for passengers to prepare for crowded terminals, longer queues, and rapid changes in flight information. Both PAL and Cebu Pacific said they would continue releasing hourly advisories until all aircraft in their fleets receive the required fix.
Despite the disruption, aviation authorities stressed that the swift response reflects adherence to global safety standards. For carriers heavily reliant on the A320 family, however, Saturday’s cancellations may be only the beginning of a challenging few days ahead—not just for airlines racing against the clock, but for thousands of Filipinos whose weekend flights turned into unexpected waiting games.
