Boeing may delay jet return

Hundreds of 737 Max planes could still be grounded until mid-August or later

The return of Boeing's 737 Max to service may be delayed until mid-August or later due to a software update and recertification, possibly creating new problems for carriers as the summer travel season approaches.

Initially, Boeing hoped to have the plane back in the air by April, but revisions to the automated flight system, the logistics of installing the software update, and approval by foreign regulators pushed the estimated return date into May and now August.
