Pat--yes, they are a totally separate entity in SXM. However, they do still have to answer to the airlines and/or PJIA, so if I have had excellent service from them, which I have had in the past, I have sent a note to AA. I would do the same thing with a complaint. I don't honestly know, but I don't think that the wheelchair folks in Miami, etc., actually work for the airlines either, but the airlines DO pay attention to complaints regarding service in Miami, as I know that from personal experience.
