Is there a list of the areas they are checking for as time goes by that we can follow. We are not in a hot spot now but where our flight connects might be at some point.
Here's a list of travel related restrictions according to Southwest. Not exhaustive, especially internationally, but I think it's pretty informative for an idea of how travel within the United States is affected.

One interesting note is that a significant number of U.S. states with some sort of quarantine/travel restriction were states that were more hesitant to implement a stay at home order. Without too much commentary, these orders were mostly implemented as a last ditch effort to keep coronavirus out of the state before there was a spike.
I just feel whatever issues/restrictions there will be with travel this summer (which there will be), it won't be blanket quarantines from individual states.
