PAL is absolute crap, you cant change amend or add anything without calling
i wanted to change dates for flight from HK to MNL, and before they would I HAD TO PAY philippine travel tax, yes I sent them my passport but it didnt change anything, still had to pay, was told I would get the 1660 pesos back at the airport ( what a load of bollix)
then several times they changed flight times/days because of empty planes.........and im the one who has to shell out
stay far far far away from PAL
