This is not entirely a oneworld question but I think (hope?) it's appropriate for the forum.

In late October I am hoping to travel to CAY (Cayenne, French Guiana) to watch a rocket launch, in conjunction with an LONE4. Sadly no OW airlines fly anywhere remotely close, but TX (Air Caraibes) and AF both fly there. I am currently thinking of using my OWE segments to get me to FDF then flying TX FDF-CAY-FDF.

Does anyone have any experience travelling to CAY? I am trying to minimise costs, so the AF MIA-CAY flight (at roughly US$1000) doesn't appeal, but at the same time many OW Caribbean flights only seem to be 3-4 times weekly which can make for some icky scheduling.
