Premise: The Cameroon Airlines Corporation, trading as Camair-Co, is an airline from Cameroon, serving as flag carrier of the country, a role which was previously filled by the now-defunct Cameroon Airlines. Camair-Co has its headquarters in the Immeuble La Rotonde in Douala, and operates out of Douala International Airport.
Hypothesis: Camair-Co took over flag carrier of the country from Cameroon Airlines.
