DUBLIN (Reuters) - Ryanair expects Boeing ( BA ) to produce 38 of its 737 MAX planes per month by the end of the summer and possibly up to 42 by October, subject to U.S. Federal Aviation Administration approval, Ryanair CEO Michael O'Leary said on Monday.

O'Leary said he was "reasonably hopeful" that Boeing ( BA ) will manage to build up production, adding that Boeing's ( BA ) delivery delays were not tied to supply chain issues.
