Delta always asks me for this info when returning to US via it's "FlyReady" process -- https://www.delta.com/us/en/travel-p...ontact-tracing
AA form looks to be here -- https://www.aa.com/contactus/forms/c...contacttracing
Info on requirement is available here - https://www.cdc.gov/port-health/lega...tact-info.html
On BA site, they refer to it as Advance Passenger Information instead of contact tracing.
