Yes, that is a BIG change. While the parameters aren't at all clear, it appears that if you don't take ANY test at all, they won't let you fly, but if you make a good faith attempt, you will still have to get tested and quarantined on SXM, but you will be able to go. The other question is how long it takes to get the results of the test back in SXM. One newspaper article said some people were waiting four DAYS, but I have seen very little posted about how long people are waiting.
