Your travel companions should follow CDC travel guidance for people who have been exposed. If you are in another country, also follow local guidance.
Maintaining distance between yourself and others is often difficult on public transportation. People may not be able to avoid crowding on airplanes, trains, or buses.
Protect yourself from COVID-19 by staying up to date with your COVID-19 vaccines and by wearing a high-quality mask on public transportation. Everyone aged 2 years or older, regardless of vaccination status, should wear a high-quality mask or respirator in indoor areas of public transportation (such as airplanes, trains, buses, ferries) and transportation hubs (such as airports, stations, and seaports), especially in locations that are crowded or poorly ventilated such as airport jetways.
All travelers should take steps to protect themselves and others.
CDC does not reimburse or help travelers get reimbursements for travel expenses as a result of canceled or delayed travel because of vaccination requirements for air passengers flying to the United States or other issues related to COVID-19. While some companies may base their policies on CDC’s travel recommendations or requirements, each company establishes its own refund policies.
In some cases, trip cancellation insurance can protect your financial investment in a trip if you need to change your itinerary in the event of an international outbreak. Visit CDC’s Travelers’ Health website if you’d like to learn more about travel insurance, including trip cancellation insurance.

Air passengers are required to provide the following contact information, to the extent that it exists, within 72 hours before their flight’s departure: full name (as it appears on their passport), address while in the United States, primary contact phone number, secondary or emergency contact phone number, and email address.
Passengers must also:
- Acknowledge that the obligation to provide complete and accurate information is a U.S. government requirement and that failure to provide complete and accurate information may result in criminal penalties.
- Confirm the information they provided is complete and accurate.
Under current federal regulations, pilots must report all illnesses and deaths to CDC before arriving to a U.S. destination. According to CDC protocols, if a sick traveler has a contagious disease that is a risk to others on board the airplane, CDC works with local and state health departments and international public health agencies to contact exposed passengers and crew.
Be sure to give the airline your current contact information when booking your ticket so you can be notified if you are exposed to a sick traveler on a flight.
