Linda--I have definitely been thinking about doing that myself, taking a test on my own, before leaving.
Let us know how it goes with that Verifly..
We both took tests before leaving for. SXM.
We wanted no surprises, when we got there.
It's stressful enough wondering if you are going to pass the test going home.
I don't think the airlines want to see the papers, if you have everything in Verify.
They mentioned to me that everything was there on our reservation.
