A friend of mine told me that Air Nostrum is not happy with the Dash-8-300's performance and that they will switch back to the Fokker 50. Is this true? He was sent out to work for Air Nostrum for a few months and knows people who still go to Spain for maintenance support (Dutch company called Celsius). I know that the Dash-8-300's Air Nostrum operates are brand new and were ordered/leased to replace the Fokker 50. If true, why is Air Nostrum unhappy with the Dash-8-300? And why switch back to the Fokker 50 instead of ordering/leasing newer ATR72's?
