Online check-in Caribair - https://www.check-in.site

I'm sorry, but as of my knowledge cutoff in September 2021, Caribair does not offer online check-in. However, please note that airline policies and procedures can change over time, so it's always best to visit Caribair's official website or contact their customer service directly to get the most up-to-date information on their check-in options, including online check-in.
