I think all domestic and international travel should have this requirement at a minimum. Nobody should be on an airplane without a recent negative test. Or working in a factory, hospital, or other indoor environment for that matter, it would be great if essential workers could all routinely get tested once or twice a week, though maybe that's not feasible. I don't really get the international focus of this either, but it seems like a step in the right direction.
