Re-entry requirements vary by country. Guests who are required to take a COVID-19 test before returning home can do so onboard for $59 USD for antigen and $85 USD for PCR. The U.S. CDC no longer requires air passengers traveling from a foreign country to the United States to show a negative COVID-19 viral test, making travel easier for our U.S. guests returning from cruises outside the country, and international guests cruising from U.S. homeports.
