Just wanted to let you guys know that there is a new option from Manila to Angeles City. Genesis Bus now operates a direct Point-to-Point service from Terminal 3 at NAIA (Manila International Airport) to SM Clark (Angeles City), and Clark Airport. The shuttle cost 350p, and runs about every hour. Buses are comfortable and roomy, unlike the vans some shuttle services are now using.
The buses do leave on time. The only down side, is that you will need to find transportation from SM Clark or Clark Airport.
