I checked with someone familiar with Changi Airport procedures and he said “we are considered a red station. Surely we have the talent and the financial resources to do a Changi Airport too. I do not subscribe to the assertion of some critics that Changi Philippines is not the same as Changi Singapore. The Changi name is at stake and I am sure Changi Singapore will make sure Clark works as well as their Singapore terminals. Megawide-GMR is building the Clark airport terminal building on a turnkey basis, meaning they will only be paid after turnover.
