Key points
Note that we have clarified the use of the term Aircraft here to mean any vehicle capable of transportation by air.
Note also that we have avoided the use of obvious terms such as airport, pilot, etc.
Key points
It should be noted that many scheduled airlines also operate chartered flights, but they do not qualify as charter airlines. In order to be classified as a charter airline, the following rules must be met:
All or most of the airline’s flights must be charter flights; and
Airlines must not sell any tickets for its charter flights directly; and
Tickets for charter flights must be sold through a travel agency (or tour operator).
This slide rounds up the basic terms needed to describe the airline business.
Key points
An airline may or may not own the aircrafts it operates (uses). Many airlines do not purchase a single aircraft; instead, they take out aircrafts on lease from someone else. Even then, an airline will need to maintain all the data mentioned above.

Key points
A GDS practically centralizes access to multiple airline CRSs, thereby making the lives of travel agents simpler. A GDS provides a single interface to schedule, availability, fare and reservation databases of multiple airlines.
Each GDS has direct connectivity to a fixed number of airlines. These airlines are known as hosted airlines for that GDS. The GDS is usually in real-time sync with its hosted airlines.
GDSs synchronize with each other to share information about their hosted airlines.
