Back in November, I mentioned in a post about its arrivals waiting area that only passengers are allowed inside the Ninoy Aquino International Airport (NAIA). This means that everyone with international flights have to show their tickets and passports before they can even enter the building. Despite having a separate entrance for Overseas Filipino Workers (OFWs), on very busy days the line of passengers snaking its way towards the entrance can be so long it spills over onto the driveway.
