MANILA, Philippines -- The management of the Ninoy Aquino International Airport (NAIA) advised air travelers, on Sunday, not to cancel their trips to and from the Philippines, saying the recent failed terrorist attack on Northwest Airlines Flight 253 in Detroit, Michigan, was an isolated incident that should not affect the entire Christmas season.

?It is a season to celebrate and that is exactly what we want our airline passengers to do - move on with their planned vacations here and abroad. Let us, the airport authority, handle their security and safety,? Alfonso Cusi, general manager of the Manila International Airport Authority said in a statement.

Meanwhile, the Department of Foreign Affairs said no Filipino passengers were on Flight 253, which came from Nigeria and passed through Amsterdam in the Netherlands en route to Detroit.

?No Filipino was affected or injured in the incident,? DFA spokesman Assistant Secretary Eduardo Malaya said in a text message, citing a report by the Philippine consulate general in Chicago, which, in turn, stated that the information was relayed by Jose Evangelista, the Filipino honorary consul in Detroit.

Cusi assured air passengers and the general public that security measures at NAIA terminals and the domestic airport ?remain strictly in place and at no point in the past were these procedures relaxed.?

He directed MIAA assistant general manager for security and emergency services Angel Atutubo to make sure that there is maximum police visibility especially in public areas. The airport chief said the deployment of K-9 dogs has also been ordered.

?High vigilance at the initial and final x-rays is likewise in place to thwart any attempt to bring in hazardous materials or explosive devices. One hundred-percent body frisking will be implemented as necessary on all flights,? he said.

Cusi said he and Director Edwin Corvera of the Philippine National Police-Aviation Security Group had discussed ways to foil any attempt to disturb flight operations through acts of unlawful interference.

The general manager said police visibility at the baggage build-up area has been enhanced with K-9 units monitoring the place. Air-side patrol was also in place 24/7, he added.

?This is when passengers realize the value of our efforts to maintain strict security and safety procedures at NAIA Terminals when other Airports have already relaxed on theirs. We would rather have people complain about redundancy checks, than be blamed for lives lost because we did not do our job,? he explained.

Tirso Serrano, assistant general manager for airport development and corporate affairs, said the MIAA prepared for the holidays when it ordered a no-leave-no-absence policy at the onset.

?Our men are on standby for any eventuality,? he said, adding that he has also MIAA?s terminal operations groups have also been ordered to be wary of suspicious looking individuals or any unusual occurrences in their areas of responsibility.

As of press time, flight operations at the NAIA remain normal.
