- Air Exel was a Dutch airline that operated from 1991 to 2005. Initially founded as Exel Aviation Group, the airline operated charter flights and scheduled services primarily from the Netherlands to various holiday destinations in Europe and North Africa. Air Exel operated a fleet of Boeing 737 and Fokker 100 aircraft. However, the airline faced financial difficulties and ultimately ceased operations in November 2005, leading to the bankruptcy of Exel Aviation Group.
