About the Boeing 777-9
The 777-9 made its first flight in January 2020. Boeing lists its length as 76.7 meters (251 feet 9 inches). The wing spans 71.8 meters with the tips extended and 64.8 meters with the tips folded. Folding the tips reduces the space the aircraft needs across the wings on the ground.
Seating capacity
Boeing’s preliminary airport planning manual illustrates a two-class layout with 426 seats. It divides them into 42 Business seats and 384 Economy seats. The number describes the manufacturer’s planning example. For a specific flight, the operating airline’s published layout determines the number and types of seats.
Cabin layout
Boeing’s drawing shows two aisles, a Business section at the front and Economy sections farther back. The drawing also shows where features such as lavatories sit relative to the seating sections. A carrier’s own plan determines which seats are next to a window or aisle and which rows are near exits. Use the row and seat letter on the airline’s map when comparing seats.
How to recognize a Boeing 777-9
Look for the long widebody fuselage and the outer ends of the wings, which can tilt upward on the ground. The folding tips help identify the 777X family. The 777-8 also belongs to that family, so use the fuselage proportions and the registration to confirm the model. An image taken at an angle can make length difficult to judge.
Variants and related aircraft
The FAA uses B779 for the 777-9 and B778 for the 777-8. The earlier 777-300ER is tracked under B77W. The term 777X identifies a family, so check the model number when selecting a radar filter.
