Just to let you know i have seen a number of good flights in the last few weeks... PAL have a sale on every weekend, Cebu have a 75% sale on at the moment and airasia have a sale starting tomorrow.
I fly out from MAN to CRK in October and i booked my domestic flights (Manila to Cagayan de Oro, Camiguin to Cebu, Cebu to Kalibo and Kalibo to Manila) yesterday and they were all very well priced (most 1,000php or less with 15kg of luggage). If you are flying out before November - have a look at booking now as i am getting to go to a few places i have wanted to go to due to the low priced flight...
Now i am just hoping December flights come on offer as i need to book them too...
