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

I'm sorry, but as of my knowledge cutoff in September 2021, Cobalt Air is no longer in operation. Cobalt Air was a Cypriot airline that ceased operations in October 2018. They filed for administration and suspended all flights abruptly, leaving passengers stranded. Since then, the airline has not resumed its services.

If there have been any recent developments or changes regarding Cobalt Air, I am unaware of them. I recommend checking with the latest sources or contacting the relevant authorities or travel agencies for up-to-date information on airline check-in procedures.
