Has anyone recently flown Swissair back to the States? How did the covid test document check work? Did you need to print out your test results or were you able to show them an email on your phone or the results on an app on your phone?
When we flew Delta back from Italy last summer it was recommended that we print out the results and that turned out to be a hassle finding somewhere to do that. Turns out they just did a cursory glance anyway.
Thanks!
