Airport security boosted nationwide

Some carriers encourage passengers to arrive earlier than usual because of longer checks

Airports around the country have stepped up security checks on passengers and their luggage to get ready for the upcoming events to mark the 70th anniversary of victory in the War of Resistance against Japanese Aggression (1937-45).

Some airlines have made announcements to suggest passengers arrive at airports at least two hours ahead of their departure time for a domestic flight and three hours for an international flight.
