I recently traveled to Davao and found that for domestic travelers, there weren't many COVID-19-specific requirements; a valid ID and your ticket were mostly what I needed. However, it's always smart to check the latest updates on travel advisories or the airline's website as situations can change. For international travelers, there might still be some health protocols in place, so having a negative test result or proof of vaccination ready could be helpful. To make the airport experience smoother, try to check in online and arrive early to avoid last-minute stress. Safe travels!
