We also flew out Saturday. We used the Verifly app. We were in the long long line. When we reached the lady with the attestation forms she asked if we had Verifly. She looked at the app on our phones and gave us a couple of papers to indicate we were good to go. She also noted we were in first class and told us to skip the line and move to the priority lane which as in another room which we could not see from where we were in line. We were in a currently unused part of the airport. We did not have to print anything out or fill out any forms at the airport because of the Verifly app.
