The Points Guy ran a video by Brian Kelly arguing “against any unnecessary travel at all.” I’m not persuaded, and hashing this out publicly should help people make up their own mind.
It can certainly make sense to do limited domestic travel this summer if you aren’t living in a coronavirus hotspot, aren’t heading towards one, and are not in a high risk group (and do not live or work with people that are). I’m not telling anyone that they should travel for leisure but the argument doesn’t hold that no one should.
