I travel for a living and have been all over the place domestically except for the areas where quarantine is mandatory (NY, NJ). And yes, we did do a trip to Puerto Vallarta, but believe it or not, we socially distanced. We didn’t do the clubs and bars and only had a short time around a group on the beach. It all went well. So, planes are safe. Hotels are safe. Just follow the guidelines and you should be ok.
