Corsair International is likely the kind of airline that most Europeans and certainly most Americans have pretty much never heard of. The airline not only operates with an extremely unique operational model, but it also exists somewhere between the spectrum of full-service airlines and low-cost carriers, which makes it extremely difficult to actually pin down. As a result, many, even long-time airline industry observers, will find it difficult to nail down an exact definition for the operational model that Corsair uses.
