Thanks Carol and others for the info about Miami. In the winter there is a direct flight from PHL to SXM so I'm lucky.....but only in the winter. Other times of the year we have to have the connected flight with AA in Miami or Charlotte. I have chosen Charlotte because the last time we landed in Miami, quite a few years ago, it was a never-ending walk to immigration and customs from where we disembarked from the plane. It was one of the last times I could walk relatively easily and even that was a difficult walk. So with this additional information about the wheel chair situation in Miami, I will make sure we don't land there.
