Here is what we are doing and I hope it helps someone. We fly out of JFK on Sunday morning and staying on the French side. For a number of reasons, we won’t be able to do the rt-PCR at 72 hours but we will be tested within the 120 hours to satisfy the Dutch side. We arrive at JFK on Saturday early evening and we will go to Jet Blue Terminal 5 where we can get a 48 hour Antigen test whose manufacturer is approved by the French side - one of the Abbott tests. I confirmed the test. Our French side hotel requires us to email the antigen results before we arrive. If worse comes to worse, we can take an Antigen test within 24-48 hours of arrival on the French side. We will take this test, if need be, at the Red Cross in Hope Estates.
