My husband ordered the Abbot Labs BinaxNow Covid-19 home test kit about 4 weeks prior to leaving. They require ordering in a quantity of 6. We both downloaded the Navica app and created accounts.
My husband also downloaded the VeriFly app and created an account. We were flying American Airlines.
We packed 4 of these covid tests in our luggage. We took the self tests at the dining table in our Airbnb in Athens on Sunday night. (We departed Athens Wednesday morning.) Our Air BnB had wifi.
When logging in to take the test, we both received messages on our phones that we needed a separate laptop/tablet to initiate the test. So, we used our iPad mini to take the test instead. It was like a Skype/zoom call, but we could not see the proctor, only they could see us. My husband logged on and took his test. He received his negative result confirmation via email in an attached PDF while I was in the middle of taking my test right after him. It look about 30 minutes to complete the test start to finish. The Abbot lab proctors talked FAST!
My husband took a screenshot of the PDF of both of our negative test results and uploaded them to VeriFly. The app confirmed that the test was accepted within minutes. He uploaded mine under his account as a family member and I was accepted within about an hour.
Upon arrival at Athens airport, the ticket agent asked if we had the VeriFly pass. We showed the "pass" on the app on the phone, and that was all that was needed.
We did NOT have to fill out a separate paper attestation form bc we had the pass with VeriFly.
