PARIS — Boeing is moving forward with a study of an all-new commercial jet that would enter service in the middle of the next decade, sales chief John Wojick said in an interview ahead of the Paris Air Show. In the past year, Wojick’s sales team has had detailed discussions with airline customers and has determined that the market is big enough to potentially go forward with a multibillion-dollar investment to build the first all-new jet since the 787 Dreamliner, launched in 2003.
