We've visited Guadeloupe three times in the past 8 years and have used Air Guadeloupe to get to Iles de Saintes from there. Other than typical "island time" delays I would highly recommend the airline. The pilots have to be fairly competent to get into some of the postage stamp runways in the French Caribbean. The flight into les Saintes is always a thrill as the pilot flies over a mountain and quickly banks left as he quickly brings it down to the runway at which time you look up and see the Atlantic waves crashing at the end of the runway.
