The Boeing Co. said late Monday that the first flight of the 787-9 was scheduled for 10 a.m. Tuesday, with the plane departing Paine Field in Everett and landing at Boeing Field in Seattle.

First flights typically last several hours. In this case, the plane is to land at Boeing Field at about 3 p.m., the company said, after which the two pilots, captains Mike Bryan and Randy Neville, will hold a news conference.

Boeing is to broadcast the events live on the Web at www.newairplane.com/787/787-9. The flight also can be tracked in real time at flighttracker.newairplane.com.

The new 787-9 is 20 feet longer than the original Dreamliner, the 787-8. The -9 will carry 250 to 290 passengers on routes of 8,000 to 8,500 nautical miles. That’s about 40 more passengers and 300 nautical miles farther than the original 787-8.

The company hopes to deliver the first 787-9 to Air New Zealand in mid-2014 after six to nine months of flight tests.
