For me there’s only one carrier and one ticket.
Luckily, too.
Yes, one ticket if the purchase is made via Air Caraïbes. But Cathy47 didn’t specify, and I hope for her sake because it would complicate the trip. I hadn’t even considered that scenario—it just seemed so obvious.
You can definitely have one ticket with multiple carriers on it, as you know. That doesn’t change the fact that the dog must be approved for the entire itinerary. It’d be the same procedure, for example, for transporting sports equipment that exceeds standard dimensions (surfboards, etc.). There are lots of factors to consider to avoid hassles and issues at the airport. But if you follow the procedure, there’s no problem.
For baggage, Air Caraïbes advises applying the most restrictive rule, for example. Same for dogs in the cabin?

I suggest she contact Air Caraïbes directly or a local travel agency near her to ensure the dog is approved for the entire itinerary.
