Couple of things that maybe of use for anyone travelling through Clark airport.

Upon arrival and once outside you'll find taxis available as well as jeepneys, but these taxis are a total rip off. If you don't negotiate a price you'll get stung for about 900p for a 15 minute trip into Angeles, and even if you do you won't get the fixed price down below 400p.
What you won't see (as in they don't want you to see), is that if you walk to your left toward the departure building you find a few yellow metered cabs. Must be some back handlers going on somewhere because it's almost as if the metered cabs are hidden out of your natural line of sight and who would come out of an arrivals hall and then head back in the direction of departures

When leaving Clark there is a 600p airport tax for international travel, which unlike NAIA is not incorporated into your ticket price, so keep some pesos at the end of your trip for this
