I believe that there is no right or wrong answer. Some flew some went by vehicle. I guess we all have to trust our guts. But this is soooo worrisome.
And @ Simb, actually I was denied entry once when I flew and they made me pay for a flight back! For some, the airlines paid for them, but I was unfortunate. I too find all of this very confusing and I find myself feeling more anxious now. I thought flying or not, my husband and I would have done what we have researched for so long without a hitch, but now idk.
