If you've got any upcoming overseas trips, be warned.
"On Tuesday, April 4, Philippine Airlines (PAL) advised passengers of international flights to be at the airport up to five hours before departure in anticipation of long lines at immigration counters," reports ABS-CBN News.
PAL told its passengers, "Please come early in anticipation of long immigration lines."
The report noted: "Immigration officers have gone on mass leave to protest the alleged non-payment of overtime work. Justice Secretary Vitaliano Aguirre, who said more than 30 personnel have resigned and 50 others are on leave, admitted that the problem may extend until the Holy Week."
While Manila International Aviation Authority (MIAA) general manager Ed Monreal said that that they have a "contingency plan" for this, it's best to heed the advice to be at the airport about five hours before your scheduled flight.
