I took a bunch of KN95s on my trip last month and then never used them after leaving Atlanta. I realized that essentially everyone on my plane had been PCR-tested and the vast majority vaccinated, and besides, it's been said that aircraft ventilation and HEPA filtration makes the plane ride probably the safest leg of the overall journey. And once you arrive in Bonaire, there is no shortage of air circulation with buildings often being only partially enclosed. I believe Bonaire is one of the safest dive destinations we have available to us right now. Enjoy your trip!
