Qatar Airways Chief Executive Akbar Al Baker said it would have been happy to announce an order for Bombardier's C-series passenger jets at the ongoing Farnborough Airshow but unspecified issues have gotten in the way of talks.

Al Baker said it was still considering the C-series and saw a need for planes of that type. The C-series is due to enter service from 2013 serving the market for single-aisle planes carrying 100-149 passengers. He declined to give further details.
