Online check-in Centurion Air Cargo - https://www.check-in.site

I'm sorry, but as of my knowledge cutoff in September 2021, Centurion Air Cargo did not offer an online check-in service. However, it's important to note that airline policies and procedures can change over time. I recommend visiting the official Centurion Air Cargo website or contacting their customer service directly to inquire about their current check-in options, including online check-in. They will be able to provide you with the most accurate and up-to-date information for your specific situation.
