PAL services were interrupted during World War II, which lasted in the Philippines from late 1941 to 1945. Upon the outbreak of the Pacific War on December 8, 1941 the two Model 18s and their pilots were pressed into military service. They were used to evacuate American fighter pilots to Australia until one was shot down over Mindanao and the other was destroyed on the ground in an air raid in Surabaya, Indonesia.[12]
On February 15, 1946, PAL resumed operations after a five-year hiatus with service to 15 domestic points with five Douglas DC-3s and a payroll of 108 names. Philippine Airlines returned to its original home, the Nielson Field in Makati. The airport, heavily damaged during the war, was refurbished and modernized by PAL at a cost of over one million pesos, quickly becoming the official port of entry for air passengers into the Philippines. The airport was operated by Manila International Air Terminal, Inc., a wholly owned PAL subsidiary.
