Do I need to pay anything at the airport when departing from Manila?

No, tourists do not need to pay anything, as all fees are already included in the ticket price. However, in some Philippine airports there is an Airport Terminal Fee that passengers must pay additionally when departing on international or domestic flights. But do not confuse the Airport Terminal Fee with the 1620 peso travel tax (Travel Fee) for Philippine citizens and residents; tourists do not need to pay it.
