Singapore from Davao or Calrk (pampanga)

I have tried the Davao- Singapore- Davao route in July 2005 through Silkair, but it is quite expensive. 25,000pesos for two-way ticket.


A cheaper option i did in January 2006 was Davao-manila- CLark- Singapore

Dvo- Manila (2,300pesos, via Cebupacificair)
Manila- Clark (300pesos by bus)
Clark- Singapore (1,500 pesos promo fare at Tigerairways.com, 4 mos advance booking)
