Akbar al-Baker, chief executive of Qatar Airways, has said the airline is 'very interested' in buying Bombardier Inc's CSeries jetliners, but needs to address commercial issues before it makes an order, Reuters has reported. The carrier had previously said it is looking to boost the number of smaller planes in its fleet and in June ordered 24 Airbus A320 series aricraft, which can carry between 107 to 185 passengers.
