You may want to consider an alternative route thru Puerto Rico.
Well the good news is Delta is being very fair with cancellations....I got a full credit with a waived change fee, good for a year, and by the terms of my ticket I wasn't entitled to that at all
It's interesting. In my interactions with Delta yesterday, they were most definitely playing a cat and mouse game. My last message to them was: "I don't believe you. I will check all my social media contacts and on-line travel forums to see what the real deal with your SXM flights might be." Literally three minutes later they offered us a full refund and admitted that SXM is not operational. Glad they responded the way they did, but sad it took the social media card to get them to step up.
