They have three large international airports serving this megapolis and all three are thriving. San Francisco International Airport is just across the bay to Oakland International Airport. That’s how close the two airports are, a lot closer than the San Miguel airport in Bulacan is to Clark. Indeed, all three international airports have been serving ever more passengers as more domestic and international flights are added. The proposed Bulacan airport is also way further away from Clark compared to the distance between SFO International and Oakland airports.
