Online check-in Air Caraibes Atlantique - https://www.check-in.site

I apologize for any confusion, but as of my knowledge cutoff in September 2021, there is no specific airline called "Air Caraibes Atlantique." It's possible that there may have been changes or updates since then.

Air Caraibes is a regional airline based in the French Caribbean and primarily operates flights within the Caribbean and between the Caribbean and France. They do not have a subsidiary or specific service called "Air Caraibes Atlantique" that I am aware of.

To obtain the most accurate and up-to-date information regarding online check-in for your Air Caraibes flight, I recommend visiting the Air Caraibes website (www.aircaraibes.com) or contacting their customer service directly. They will be able to provide you with the necessary information and guidance for checking in online for your specific flight.
