Online check-in Cavok Air - https://www.check-in.site

I'm sorry, but as of my knowledge cutoff in September 2021, I couldn't find specific information about an airline called "Cavok Air." It's possible that Cavok Air is a regional or new airline that has emerged since then. I recommend visiting Cavok Air's official website or contacting their customer service directly for information about online check-in procedures. They will be able to provide you with the most up-to-date and accurate information regarding their online check-in process.
