New Manila International Airport (under construction)

Not applicable. The airport has not been closed. The premise of the query is incorrect as the facility is being built from the ground up on a new site.

The site is an active, large-scale land development and construction zone. Activities include extensive dredging, land reclamation, and the initial phases of infrastructure construction for the passenger terminals, four parallel runways, and an associated 'aerotropolis' city. The project is officially named the New Manila International Airport (NMIA). The ICAO code PH-0349 is a temporary, unofficial identifier likely for a heliport or a point on an aeronautical map related to the construction site, not the final ICAO code for the international airport.

The airport has no operational history. Its significance is entirely future-oriented. It is being developed by San Miguel Corporation (SMC) as the Philippines' next premier international gateway, designed to be one of the largest and most modern airports in the world. Its purpose is to decongest the aging Ninoy Aquino International Airport (NAIA) in Manila and to create a major economic hub north of the capital. The site itself was previously comprised of coastal areas, including fishing villages and fishponds in Taliptip and Bambang, Bulakan, Bulacan.

The concept of 'reopening' is not applicable. The project is focused on its initial 'opening'. The first phase of the airport is projected to be completed and become operational around 2027. However, timelines for mega-projects of this scale are often subject to adjustments based on construction progress, financing, and regulatory approvals.
