As of early 2026, most international and domestic airlines no longer require a negative COVID-19 test for general travel, as the world has transitioned to managing the virus similarly to other respiratory illnesses. However, the requirement is now largely destination-specific. While major hubs in Europe, North America, and most of Asia have dropped all mandates, certain countries or specific tour groups, cruises, and large-scale events may still require proof of vaccination or a negative test for entry. For example, some countries may "preferably" suggest travelers be fully vaccinated. It is a high-value strategy to check the official embassy website of your destination or use a tool like IATA Travel Centre 72 hours before your flight to confirm current protocols. Even if not required, carrying a few rapid tests in your luggage is a smart peer-to-peer tip, as getting sick while abroad can still impact your ability to attend events or your comfort during the return journey.
