Bombardier has secured another CSeries order but, as was the case earlier in the week, from an airline not-yet ready to put its name to the deal.

The contract is from a European customer, the Canadian aircraft maker says, and is a firm order for 10 Bombardier CS100s. The aircraft maker says the deal is with a new customer that has not operated Bombardier aircraft previously.

The value of the deal is $628 million.

After a dismal Farnborough air show last year, in which it failed to secure a single order, Gary R. Scott, president of Bombardier Commercial Aircraft, says, “this order tops off a very successful Paris air show and a strong wave of order activity in June, when we added five new customers.”

But the CSeries orders are overshadowed, somewhat, by the massive order intake Airbus has secured for its A320NEO (new engine option), including the launch order from Republic Airways for the Airbus A319NEO, the closest competitor to the Bombardier narrowbody. Republic Airways also is a CSeries customer, and says it has no plans to cancel its CSeries commitment despite the A319NEO order. Analysts, however, question the sense in buying both types.
