Air Caraibes (sp) Martinique to Grand Case is a possibility, but we are having a hard time figuring out the Saint Lucia to Martinique piece. The must be a puddle hopper that will work, but we haven't found it yet. Will keep looking.
Also. will check out via Barbados and Trinidad connection options.
Any of you have a Gulfstream 7 we could borrow for a couple of hours?
