Yes, it is offical. Tonight, 9/6 at 8:00pm TST, the news reported that Chiang Kai Shek International Airport (CKS) is no more! It is now renamed
Taiwan Touyuan International Airport. It will keep its official TPE code.
Intersting tidbit on the news along with this is that to make it easier to pronounce, they shorten Taiwan Touyuan to Tai Tou. In the mother tongue, Taiwanese, "tai tou" means 'cut off your head'.
Hello?! You'd think the Chen government might consider that before renaming.
Here is the link from the IHT. I'm still working on the local papers.
