Airbus notched a single order this year for its worst-selling plane

• Airbus secured a single order for its worst-selling A330-800neo widebody airliner this year. 
• The plane is a shrunk version of the A330-900neo and has only secured 12 orders since its debut in 2014.
• Airlines have opted for aircraft with better per-seat costs, like the Boeing 787 Dreamliner.

While Airbus has had no trouble selling its next-generation A330-900neo, the widebody jetliner's little brother is struggling to keep up.
