I know this may sound a bit crazy.... but a few years ago, when my husband and I were still visiting SXM, we spoke to a man who had come to the island with a large family group. They had found it more economical to hire a private plane rather than to all fly commercial. If there were enough people who could band together on this, would a private plane make any sense? Even if it only got you all to a point where other flights were available.
