That's about right
I've just come from NAIA
Travel Tax was P1620 (Filipino or foreigner staying more than a year?)
Terminal Fee was P550, although rumoured maybe going back to P750 soon
ACR-I holder P2880
You can pay the Terminal fee in $ or P, but not the ACR has to be P
Travel tax was automatically on my Cathay Pacific ticket, not sure how they worked out I needed it as I was not ask for Immigration status when booking.
Its more funds in the Philippines
