Recent Experiences on Entering Philippines:

Covid test required with negative result - either antigen test no more than 24 hours before flight or RT-PCR test no more than 48 hours before flight. Antigen tests are much cheaper, I found. Had test kits delivered to an address, took tests (all negative), took photo of test result and sent off with photo of passport. Result certificate received within 10 minutes. Printed them off and no questions asked on arrival.

Arrival in Phils requires:

1. Negative Covid test as described above.
2. Registration on One Health Pass. Be careful with this - can only register within 3 days of travel and if you make a mistake, as I did, some things cannot be retrospectively changed through the 'Edit' section of your profile details. Print off or save to phone the QR Code page that is sent via email.
3. Make sure you have VaxcertPH certificate.
4. KEEP YOUR BOARDING PASS(ES). Several travellers I overheard falling foul of this. BOQ will stamp the boarding pass after checking all other documents at the airport before arrival at passport control. If you cannot show a boarding pass, it seems that you get shunted aside for some other kind of check before being allowed to leave the airport.

Allow time for all of this process. If you are travelling with young kids or have disabled members in your party, you will get some priority, but can still add around 30 minutes to the process, more if you don't.
