SkyTeam alliance member Delta Air Lines' order for 100 Boeing 737-900ERs does not rule out the possibility that Bombardier may yet win a CSeries order from the US major, report noted analysts.
"Delta has got a lot of 757s to replace, and for that matter, MD-88s, both of which are above CSeries seating capacity. The fact that they've ordered a lot of airplanes in those size categories does not necessarily preclude a CSeries order," said George Hamlin, president of Hamlin Transportation Consulting.
Teal Group vice-president, analysis Richard Aboulafia noted that the 737-900ER "leaves a lot of leeway for a smaller jet".
"It would be really interesting to see what Embraer offers. But Delta is very much an opportunity [for Bombardier]. Delta is extremely important," added Aboulafia.
Like a number of other analysts, Aboulafia believes Bombardier needs to secure at least a slice of activity from Delta's fleet renewal efforts or else risk seeing the CSeries programme suffer.
But Bombardier Commercial Aircraft president Gary Scott, who is retiring on 1 October, has previously said: "The CSeries is ideal for [Delta's] network, so I'll be disappointed if they don't order some CSeries eventually, but does our programme depend on it? No. Are they incredibly important? Yes."
