ATR aircraft are recognized by the whole aviation industry as the greenest in their class size and offer the lowest operating and maintenance costs in its market sector.
Looking back at the history, during the 1980s, French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia merged their separate work upon a new generation of regional aircraft together.
For this purpose, a new jointly-owned company was established, ATR, for the purpose of developing, manufacturing, and marketing their first airliner, which was later designated as the ATR 42.

To date, all of the ATR series have been completed at the company's final assembly line in Toulouse, France.
Successive models of the ATR 72, a twin-engine turboprop have been developed and introduced.

The number "72" in its name is derived from the aircraft's standard seating configuration in a passenger-carrying configuration, which could seat 72-78 passengers in a single-class arrangement.
Another sign that Asian airlines believe in the product, is that already 48 operators in 25 Asian countries are flying ATRs on their routes.
