Uh, did they just switch terminals? Couple weeks ago mostly Domestic was T1 and Internationals T2. I have a picture of the departure level dropoff sign at T2 station 24-25 and it has among others NWA, Delta and American Airlines listed. It also lists "International Hong Kong-Macau-Taiwan Entry". I also met an arrving pax from Hong Kong (not sure which airline) and it was T2.
