With Seattle becoming the first major city to vaccinate 70% of eligible residents, people are increasingly booking flights and making their way to Seattle-Tacoma International Airport. Travel is high on many people’s summertime bucket lists, especially since Washington state is planning to drop all remaining COVID-19 restrictions by June 30, the European Union is reopening to tourists, and there’s been talk about the U.S.-Canada border reopening this summer.

Last week, the U.S. State Department updated its full list of travel advisories for every country, lowering over 50 countries and territories from Level 4 (“Do not travel”) to Level 3 (“Reconsider travel”). The list also includes over 25 travel destinations placed into the first two levels, indicating moderate-to-low levels of COVID-19 and instructions to exercise precautions.

The State Department currently has four risk assessment levels to guide travelers:

  • Level 1: Exercise normal precautions
  • Level 2: Exercise increased caution
  • Level 3: Reconsider travel
  • Level 4: Do not travel

With public health experts recommending that travelers spend the minimum amount of time in airports, consumers may be eyeing nonstop flights to get to their favorite destinations. You can currently travel to 16 international destinations on nonstop flights out of Sea-Tac. Here are the State Department’s newest travel advisory levels for each country.

As of June 9, Sea-Tac reinstated Condor’s international nonstop flight to Frankfurt, Germany. Seoul, South Korea, is the only international city you can fly to nonstop from Seattle-Tacoma International Airport that has a travel advisory under Level 3. Seoul is rated a Level 1. Icelandair has also resumed its nonstop flight to Reykjavík, Iceland, that it suspended during the pandemic.

Regardless of whether you are fully vaccinated or not, you should still exercise caution when traveling through airports by wearing a mask and practicing social distancing. The COVID-19 vaccine is not 100% effective, and infectious-disease experts warn that vaccinated people may still be able to infect others. And remember: Just because the U.S. State Department says you can travel somewhere doesn’t guarantee that country is open to American tourists.
