My wife is traveling to the Philippines next week with my 21 month old son. My wife is a citizen of the Philippines traveling on a Philippines passport. My son is traveling on a US passport. My understanding is that my son is at least eligible for a 1-year visa (if not visa exempt). Will he need to present an onward ticket? They are planning to return on award tickets, but availability on CX generally shows up six days in advance of the flight, which will be after they arrive in the PI.
