Article linked below. The highlights...
- Pertains to selected flights between Atlanta and Rome
- Passengers tested 3 times (72 hours prior to departure, at departure, at arrival.)
- If all tests negative, no quarantine upon arrival
- For US citizens, only applies for those travelling for essential reasons
So, not for us mere tourists yet, but a step in the right direction.
