At least 45 people died due to flooding and landslides in Mindanao, all of which occurring a day before the storm made its landfalls.[17] Initially, 72 people were reported to have died, but the death toll was revised by the National Disaster Risk Reduction and Management Council (NDRRMC) because of erroneous counting on the part of local officials;[17][18] however, the death toll would increase to 112 by November 1 as more bodies were recovered.[19][20] More than a hundred flights were cancelled in the Philippines on October 28 and 29, most of which going to and coming from Ninoy Aquino International Airport.[21][22] The storm also delayed the removal of the wreckage of Korean Air Flight 631 after it overran the runway at Mactan–Cebu International Airport.[23] After Nalgae was upgraded to a severe tropical storm, PAGASA put up Tropical Cyclone Wind Signal Number 3 warnings in several areas of Southern Luzon, including Metro Manila.[8]
