A recent article in The Gateway, the official newsletter of the airport authority, revealed that the alert level at all terminals and immediate surroundings remains high, with officials saying they cannot afford to have a single lapse in security.
Because of this, stricter measures are being implemented.
Among others, rigid inspection of all persons and vehicles is being conducted, covering all parking areas under the jurisdiction of the MIAA.
Rigid inspection of all hand-carried bags and items in the possession of departing passengers and all airport users is being made at the final security check area.
Passengers are also required to declare all baggage containing electronic devices at check-in counters for evaluation.
"Failure to do so may result in barring the passenger from boarding the aircraft," MIAA said.
Airport security has also requested departing passengers to be at the airport "four hours" in advance of their check-in time to avoid flight delays.
The MIAA article said that aircraft movement areas (AMAs) have been given priority attention.
Hence, they said, entry employees, vehicles and equipment at AMAs are being restricted, unless mandatory requirements, such as an AMA vehicle sticker and beacon lights, are met.
The practice of escorting unauthorized vehicles and other ramp equipment has been prohibited. Permanent closure of Crash Gate 1 is also being implemented.
MIAA said they have been classified as Category 1, considered as the highest safety standard, by the United States Federal Aviation Authority (FAA) in early 2003.
But despite the excellent rating, MIAA continues to implement rigid security procedures as part of the governments anti-terror campaign.
Airport police personnel have received additional training and attended seminars on security. Bomb and drug-sniffing K-9 dogs were also acquired. The MIAA also purchased patrol vehicles and other electronic detection devices under its emergency purchase plan.
Various seminars and training regarding safety and security awareness, procedures and policies were conducted for airport police and civilian employees of the MIAA to enable them to understand the importance of keeping NAIA safe from any terrorist attacks.
MIAA General Manager Edgardo Manda said the airport authority is not letting its guard down in terms of security measures, assuring the public of rigid, constant and invariable airport preparedness against terrorists and other negative elements, the MIAA article said.
