Yes and No. The original "plan" was. If you don't have a PCR -- you do a cuarentena of 14 days. And as of 8 Jan, EVERYONE [residents/citizens] flying in must have a PCR to board the plane. Now with the new rules, you need a PCR either at the point of origin or done at the airport in EZE + cuarentena for 7 days. The saliva test won't cut it.Correct me if I'm wrong, but I think I read that if you can't or don't get the pcr test before flying to Argentina, you can do the saliva test in Ezeiza.
