In the wake of the Boeing 737 MAX crisis, airlines are worried about the scheduled deliveries of the newest Boeing aircraft – 777X. Among the concerned airlines are Emirates and Lufthansa, the Wall Street Journal reports.

However, CEO of Boeing, Dennis A. Muilenburg speaking at the Bernstein Strategic Decisions Conference, said that MAX matters are unlikely to impact tests and certification of the 777X.

“I don’t see anything there right now that would significantly alter the timeline for the 777X, but it’s possible we could see something that would alter the content of the test program or how we go about certification”.

The intention to make the first flight of the largest twin-engine commercial jet in history was expected by the end of June, according to Reuters, indicating sources from the manufacturer.
