Gulf Air and Japan Airlines Join the Push for JetZero’s All-Wing Z4

Airlines from Bahrain and Japan just threw their weight behind a plane that looks nothing like the ones filling today’s skies. At the Farnborough Air Show this week, Gulf Air signed a letter of intent for an undisclosed number of JetZero Z4 aircraft, locking in preferential delivery slots for the early 2030s. Japan Airlines followed with a formal support agreement that puts its operational teams inside the design process from the start.

Gulf Air’s new deal puts the carrier at the forefront of the Z4, as it is the first Middle Eastern airline to support the project. Bahrain’s national airline believes the new plane is exactly what it needs to expand its network of routes across Europe and Asia, and it has the advantage of being the first to take possession. According to JetZero CEO Tom O’Leary, the agreement is a vote of confidence in the Z4’s capacity to give customers with a completely new level of experience at a lower cost per seat, while also being significantly more cost-effective for airlines.

At the same time, Japan Airlines announced its own agreement with JetZero, which will see them collaborate on everything from flight operations to passenger service. Takao Suzuki, JAL’s chief strategist, said the step is critical to the company’s long-term aim of achieving net-zero emissions by 2050. JetZero’s intentions for the Z4 to touch the runways in the early 2030s align precisely with JAL’s own fleet plans, thus the two firms are on the same page in terms of timeframe. That brings two more airlines to the table, joining Delta, United, Alaska, and EasyJet for a total of 17 airlines providing JetZero with the real-world feedback it need to shape its design.

Now, about the plane itself. The Z4 is a bit of an outlier, with a blended wing body design that eliminates the tube and wing configuration and instead combines the wings and fuselage as a continuous surface. According to JetZero, that is enough to reduce fuel consumption by up to 50% on mid-sized aircraft flying similar routes. It’s planned to carry roughly 250 passengers over a distance of up to 5,000 nautical miles, putting it exactly in the middle of the market where the 757 and 767 used to rule, and unlike some of its potential competitors, the engines are located at the back of the plane, high up on the body.

It means quieter cabins and the possibility of using sustainable aviation fuel instead of traditional jet fuel, and the Pratt & Whitney PW2040-class powerplants that are likely to be installed are designed with all of this in mind. Then there’s the cabin, with wider boarding doors, distinct inner cabins, and each seat having its own dedicated overhead storage area. One advantage is that the plane is designed to integrate seamlessly with existing airport infrastructure, eliminating the need for specific gates or taxiways.

Factory work is now underway, with JetZero breaking ground in mid-June on a gigantic 8 million square foot factory and final assembly plant sprawled across more than 600 acres near to the Piedmont Triad International Airport in Greensboro, North Carolina. The project is a significant undertaking, costing $4.7 billion, and is expected to create 14,500 new employment over the next decade. North Carolina created a massive incentive package for the state, one of the largest ever awarded to a company. Then, on July 21, the US Export-Import Bank signed a letter of intent that may release up to $3 billion in financing through its Make More in America initiative. This money will be utilized to help with building, production setup, and purchasing necessary equipment. JetZero intends to relocate its headquarters from California to Greensboro sometime in early 2027.

As the factory in Greensboro takes shape, the team at Northrop Grumman’s Scaled Composites plant in Mojave, California, works on the full-scale demonstrator. The primary section in the middle is now being assembled. They plan to launch their first flight in the fourth quarter of 2027. They’ve already flown a smaller Pathfinder demo to collect all of the necessary aerodynamic data. JetZero expects to submit its proposal for type certification later this year. With commercial production slated to begin by the end of 2030, they hope to have passenger flights operational by the early 2030s.
