It's done in Bohol, Iloilo, Bacolod, Puerto Princessa last few years, moving the airport out of town. And those are just the airports I coincidentally know of.
The fact that there are more serious issues to take care of is totally irrelevant, thats whats so hard to see here. Its about making money, filling the pockets and for sure thats what is going to happen. Look at all the roads and bridges being rebuild up north, its crazy and for sure there is better use for that money. Just put some tarmac on those cement roads, lots of it was just made last five years after the quake.
But projects like that will all ways happen if there is money to be made for people in the 'right spot'.... So also with the bacong or antulang airport.... or wherever it will be.
