I've just been reading the small print for my Cebu Pac round trip flight from HKG to MNL in Aug, and it states there is a Travel Tax fee of 1620 PHP to pay, except for those exempt.
Is this only for Filipino's? I flew with Cebu Pac from Manila to Singapore last year and didn't pay anything then, and with PAL from HK to MNL in Jan this year and didn't pay anything.
