You might be right about KLM. I remember having to fly Air France from JFK to Guadalupe around the same time. When I mentioned that KLM & Air France didn't fly into SXM I was thinking of from Europe. I had a French friend that lived in Grand Case and she had to fly into San Juan or Guadalupe coming from Paris. As for KLM, they flew to Curacao and then people frying onto SXM would take ALM. I'm sure you remember the white planes with the light blue and orange markings. I think ALM was owned by KLM. I know the "A" stood for Antillian and they flew to the ABC islands and SXM. Around that time SXM was not a big travel destination for the Dutch or French.
