Hong Kong International Airport (1998)
Hong Kong replaced the cramped Kai Tak airport, whose runway jutted into Victoria Harbour with planes threading between apartment towers, with a new airport on reclaimed land at Chek Lap Kok.
The opening night was chaotic, with computer glitches stranding luggage and delaying flights for weeks.
Hong Kong International Airport grew into a major Asian cargo and transit hub, handling tens of millions of passengers annually.
Like Hong Kong, Sydney built a new airport to escape site constraints — but Sydney is adding capacity alongside its existing hub, not replacing it, so the growth outcome is less predetermined.
