how to book flight ticket, from Cebu to Kota Kinabalu ? Can I have some promotional ticket?

as I will go to Philippine for a trip, and wanna to Kinabalu National Park and then Kuching.

You are going to Cebu from your country of Origin first before you travel to Kota KInabalu ? If so , then you have to fly to Clark via Cebu Pacific from Cebu , they have the 99++ flight one way from Cebu to Clark , go to www.cebupacificair.com , your fare will come to like 1,200.00pesos/one way , book early like a month .So before you book your Cebu Clark , also you need to confirm your Kota Kinabalu Flight from Calrk Airbase in Angeles , where Cebu Pacific will land. To book on a very cheap flight to Kota Kinabalu from Clark , you have to go to www.airasia.com , if you book now and travel by middle of Feb onwards , your fare One Way is like 1.750.00 pesos/one way , the ETD is 4:35 PM so you could book your Cebu – Clark like ETD Cebu at 1:00 PM or earlier so your ETA CLark is like 2 PM . giving you enough time to clear customs for your trip to Kota Kinabalu ETA is 6:35PM . From KK , you could get flight to Kuching tru airasia too , but you have to stay overnight in KK for your travel to Kuching will be next morning .Go to the sites Ive mentioned , so you could plan your trip according to your Philippine Visit. Have your credit Card ready , they accept VIsa and Mastercard . This are secure transaction lines. Ive tried this like 8 times.
