This past week the CDC lifted the Covid testing requirement for passengers returning to the United States from overseas. The past 20+ months of needed tests have not been awful in my opinion - in fact, it gave me peace of mind to know that passengers were negative prior to long flights.
The Swiss notification is here: https://ch.usembassy.gov/visas/nonimmigrant-visas/covid-19-travel-to-the-united-states/
I may continue to do this anyway on future trips - the box doesn't take up much space and I'd prefer to know before I fly. We'll see if availability for the tests changes.
