Face Masks Optional, but Recommended by CDC
TSA no longer requires face masks on public transportation and in transportation hubs like SEA Airport. Masks are optional, but the CDC recommends that people over the age of two properly wear a well-fitting mask or respirator over the nose and mouth in indoor areas of public transportation (such as airplanes, trains, buses, ferries) and transportation hubs (such as airports, stations, and seaports).
When people properly wear a well-fitting mask or respirator, they protect themselves and those around them, and help keep travel and public transportation safer for everyone. Wearing a well-fitting mask or respirator is most beneficial in crowded or poorly ventilated locations, such as airport jetways. CDC also encourages operators of public transportation and transportation hubs to support mask wearing by all people. Please check with your airline and destination for more information on masking requirements.
