I have a pretty flexible business. I have been thinking about what I will and won't do, travel wise. I have decided to keep traveling but to plan around getting sick overseas. I won't die, but it might mean I can't get on a plane to go to my next destination. So I am being very careful with how I plan my travel, so that if I do have to miss a plane ride, its not the end of the world.
So for example, I had a trip that was going to have a week of leisure in NYC and then a week of business in LA. I am looking to switch it around now: that way, I can make my LA trip and if I get sick in LA and have to skip the NYC portion, its not the end of the world.
The other thing I'll be doing is going into self isolation around 1-2 prior to any international trip, to minimise the chances I'll get sick. Because if I get sick, then no flight!
I am also going to fly business class exclusively and sit near the front of the planes. It is probably only a minimal advantage, but if it's 2-3 rows either side in economy that are the "danger zone" then sitting in the front without anyone on that side just helps minimise your virus footprint at the very least.
