The nickname for the Avros was "Jumbolino" because of the 4 engines and the striking shape. The Avro RJ100 and its smaller version, the Avro RJ85, formed the backbone of the SWISS European fleet since the company was founded in 2002. The Avro fleet has completed over 700,000 hours in the air. During that time SWISS made over half a million flights with this British Aerospace (BAe) aircraft.
