First flight of Boeing's 777X set for Thursday: sources

Following months of delay on a plane under development, Boeing plans the first flight for its new long-range 777X on Thursday, two people with knowledge of the matter said Tuesday. The progress on the 777X comes as Boeing's broader prospects remain clouded by the crisis surrounding the 737 MAX, which has been grounded since March following two deadly crashes.

The date for the first flight, a key step before Boeing seeks federal certification on the new wide-body plane, could still slip depending on weather, the sources said. The aerospace giant is also seeking to raise at least $10 billion from leading banks due to increased costs connected to the MAX situation, banking sources told AFP.
