Yah, you tell him that statistically flying is waaaaaay safer than driving all that distance. I loved this quote that actually puts the whole 'pandemic' into perspective:
“People have a very weird perception of large numbers. If you have 2,000 cases of flu in a country of 300 million, most people think they’re going to be one of the 2,000, not one of the 299,998,000.” As a friend pointed out, its the same thing that drives ticket sales for the lotto.
Book your flight, and enjoy your trip, especially knowing that you're doing the right thing by flying. GL.
