The 777X family includes the 777-8X and the 777-9X. The 777X will be the largest and most efficient twin-engine jet in the world, with 12 percent lower fuel consumption and 10 percent lower operating costs than the competition. Opening new growth opportunities for airlines, the 777-9X offers seating for more than 400 passengers, depending on an airline's configuration choices. With a range of more than 8,200 nautical miles (15,185 km), the airplane will have the lowest operating cost per seat of any commercial airplane. The second member of the family, the 777-8X, will be the most flexible jet in the world. The airplane will seat 350 passengers and offer an incredible range capability of more than 9,300 nautical miles (17,220 km). The 777X introduces the latest technologies in multiple places, including the most advanced commercial engine ever – the GE9X by GE Aviation – and an all-new high-efficiency composite wing that has a longer span than today's 777. The airplane's folding, raked wingtip and optimized span deliver greater efficiency, significant fuel savings and complete airport gate compatibility.

MIAMI — The World Trade Organization (WTO) has ruled out today that a tax break from Washington State to help Boeing develop its 777X widebody program was a prohibited subsidy.

Back in November 2013, Washington state lawmakers were asked by Washington Governor Jay Inslee to approve a package of incentives that could ensure that the Boeing 777X airplanes would be built exclusively in Washington State. The incentives included an extension of commercial airplane tax breaks through 2040, including Business and Occupancy (B&O) taxes, sales & use tax exemptions, and breaks for property and building projects.

According to the report from the WTO Panel (DS487), the tax break belongs to “a special category (…) which Members have deemed to create such trade distortions that they are proscribed,” as these are “specifically designed to affect trade.”

“The United States and Boeing picked this fight at the WTO, and today’s ruling is yet another blow for that strategy,” said Tom Enders, chief executive officer, Airbus Group.

“We hope this outcome will lead those at Boeing who advocate continuing this trade dispute to reconsider,” Enders continued.

On the other hand, Boeing has claimed a “complete victory for the United StatesWashington State and Boeing.”

According to the airframer, the WTO rejected the European Union’s challenge to six of the seven tax measures and rejected most of the challenge to the seventh. The panel from the WTO found that to date Boeing has not received any benefit from the 777X incentives, and will not until 2020, as the first airplane will not be delivered until then.

“The WTO found in September that Airbus has received $22 billion in illegal subsidies from the EU and that without these subsidies neither Airbus itself nor any of its airplanes would even exist today,” J. Michael Luttig, Boeing’s general counsel said in a statement.

“By contrast, in rejecting virtually every claim made by the EU in this case, the WTO found today that Boeing has not received a penny of impermissible subsidies,” Luttig concluded.
