Cebu Pacifc Air requires proof of onward travel?
I'm planning a trip to the Philippines in November and have already booked a one-way from HGK to CEB on Cebu Pacific. Since I want to decide at short notice when and from where to fly back to HKG I thought I could book the return only a couple of days in advance. But now I've heard that Cebu Pacific staff requires a printed confirmation of an onward or return flight, otherwise they won't let you board the flight into the Philippines.
I was absolutely not aware of this condition and cannot remember to have seen any hint on their website while booking the inbound flight.
Can anyone confirm that they have a rule like this? Or will I be fine to get on the flight to CEB without a return ticket? I will stay within the 21 day visa waiver time, if that matters.
