I just flew back from Paris to JFK. They offered this to me, and I laughed at it. Got the notification about 70 minutes later that it was done. Since I got my negative covid test back at 5PM the day before I left, which is what is needed for the silly US rules (and I am a US Citizen by birth, doesn't mean I admire our inept government) I had no worry, In addition, I figured that with a printed copy, the AA check in at CDG could inout it if needed, which is what was done at JFK for my departure as per Veriflop, I was 10 minutes late for the cutoff to scan it in. I truly hate veriflop, but use it so it minimizes my wait time to get thru check in . Don't pay the fee, its just a money grab from the as they use staff in I(nodal they pay less than the fees they charge us.
