As of my last knowledge update in January 2022, there isn't a widely recognized airline called "Coredon Airlines." It's possible that this is a misspelling or a less well-known or regional airline that may not be part of major global alliances.
If "Coredon Airlines" is a new or regional airline that emerged after my last training data in January 2022, I wouldn't have information on it. To get the most accurate and up-to-date information, I recommend checking their official website or other reliable sources for the latest news and updates.
