Hi Leo.
Arriving at Clark apparently can involve negotiating a whole bunch of rip-off taxi touts... all looking for p500 upwards to get you out of the airport. (So far I've only departed from there).
There is a proper 'official' aircon jeepney, which runs to and from Dau bus terminal... which is perhaps where you would need to go ? Cost is p100. It is white in colour. I used that.
There are also supposed to be taxis with working METERS now too ! Good luck finding one of those.
Anyway, take your time when you come out of arrivals, and look around for alternative forms and prices of transport. Don't be bullied by the taxi mafia.
