2018 A Good Start For Boeing Business Jets On the first day of the European Business Aviation Conference & Exhibition (EBACE), Boeing Business Jets took the opportunity to update the industry on their current position. They seem to have started the year well. BBJ chief executive Greg Laxton suggested the notion this morning. Four new orders have come in so far which include two for the BBJ version of the 737 MAX. So far, the 737 MAX backlog is for 19 aircraft.
