I do understand/appreciate your plight and it is Literally life and death for everyone involved.

I will say here and applies to anyone else in your situation reading.

Keep trying but:

You are stranded. Do you have a place to stay on the island for an extended time with provisions. I might look for one.

There are U.S. citizens all over the Earth right now.

I’m not sure where SXM ranks on a rescue flight compared to those other countries and cities. It is not the Hurricane story this is everywhere.

If you get into the U.S. you might get stuck in that city. Is that better than SXM?

As some one else mentioned, possibly a charter directly to home.
