Contact Tracing

Nothing is more important to Delta and our partner airlines across the globe than the health and safety of our customers and employees. In accordance with an order issued by the U.S. Centers for Disease Control and Prevention (CDC), all travelers entering the United States, including U.S. citizens and residents, must provide their contact information while in the U.S. Customers can provide this information using Delta FlyReady. Find out more about how Delta is sharing information with our partners at the CDC via U.S. Customs and Border Protection (CBP).

What is Contact Tracing? 

Contact tracing is a process already being used in many countries and communities around the world to identify and alert those who have come into close contact with the COVID-19 virus to help reduce exposure and transmission. This is mandatory for all travelers entering the U.S., including U.S. citizens and residents. 

You will be asked to provide your address while in the U.S. and a phone number. This information, in addition to contact information you provided during ticket purchase or at check-in, will be shared with the CDC via U.S. Customs and Border Protection (CBP).*

If there is a suspected case identified on board after your flight, the CDC will work directly with local health departments to contact you and provide follow-up instructions for testing and/or potential quarantine. 

Follow-up of travelers is at the discretion of health departments and may be considered by jurisdictions implementing safety measures.

Who Must Participate?

Delta and our global partners are working diligently with our respective government agencies, health officials and aviation authorities to offer safer travel at every point in your journey.

Contact tracing is required for everyone traveling to the U.S. as their final destination or connecting through, including U.S. citizens and residents.

For other international travel, you and those in your itinerary can voluntarily participate if you are traveling on a Delta operated flight or flying on a global partner airline ticket with a Delta operated segment.
