Boeing must sell more 777 and 787 jetliners to keep production plans on track, despite a $13.8 billion order that landed earlier on Thursday, its chief executive said.
The order from high-profile customer Singapore Airlines is a strong endorsement of both planes, and could lift sales in a sluggish market if other carriers follow Singapore Air's lead, analysts said.
But the win over rival Airbus did not lessen two big risks Boeing faces, Chief Executive Officer Dennis Muilenburg said on Thursday at a conference in New York hosted by Cowen and Co.
Sales of Boeing's highly profitable 777s have slowed so much that Boeing is cutting production 40 percent this year to cope as it begins switching to the successor 777X model that Singapore Airlines ordered.
"When I take a look at risk areas, filling out the 777 bridge is the area that we're focused on," Muilenburg said, referring to the production spanning the two models.
