A temporary COVID-era rule that let the CDC make airlines collect and share certain passenger and crew contact details has ended.
This means the CDC no longer has that extra, special authority from 2020 to quickly get traveler data for things like health warnings, treatment, or travel limits.
If you fly into the U.S. from another country, you may see fewer emergency-style data requests tied to this old COVID rule, though normal travel screening can still happen.
The rest of the long-standing foreign quarantine rules stay in place, so the government still has tools to respond to serious contagious disease threats.
