Alaska Airlines was the first U.S. carrier to invest in a new company behind a futuristic aircraft design that could one day quite soon fly to and from the islands. And with the Hawaiian brand now under Alaska’s wing, that raises a new question: could Hawaii travelers be among the first in the world to board this radically different plane?
The U.S. Air Force is already backing the effort, and Delta and United Airlines are engaged as well. It comes at a time when airlines are increasingly frustrated with Boeing and Airbus, and are now looking elsewhere for next-generation solutions.
The JetZero Z4 is a next-gen blended wing body airliner. It doesn’t look like any commercial aircraft flying today—and that’s the point. With a design that merges its wings and fuselage into one aerodynamic body, the Z4 promises up to 50 percent lower fuel burn, reduced emissions, and a roomier interior experience.
Could this plane reshape Hawaii flights in the decade ahead? Construction of a full-scale demonstrator is actually underway, and a potential commercial debut could happen by the early 2030s.
Unlike the tube-and-wing planes we know and fly in today, this new aircraft merges the fuselage and wings into a unique, single, wide aerodynamic body. That unusual shape could reduce fuel burn by up to 50 percent while offering radically more usable interior space and less environmental impact. The U.S. Air Force is already backing it, and now it’s gaining traction with three major airlines flying to and from Hawaii.
Building the JetZero Z4: current progress and more.
The California aerospace startup behind this airliner has already completed its preliminary design review for a full-size prototype in partnership with Northrop Grumman and Scaled Composites. That demonstrator will be approximately the size of a Boeing 767 and is expected to fly in the next two years under a $235 million U.S. Air Force contract.
The goal is to prove the aircraft’s performance and safety credentials with the FAA and then pursue commercial certification. That process will still take years, but the aircraft is being built, unlike other ventures, not just imagined.
Alaska Airlines has invested strategically in JetZero, secured purchase rights for future aircraft, and is playing an advisory role in shaping how the plane could be used, including potentially routes to and from Hawaii. Delta is contributing to the design and development process, while United has also made a conditional commitment to purchase up to 200 aircraft if performance and certification milestones are met.
The Z4 airliner is expected to carry 250 passengers and fly over 5,700 miles, easily enough range to handle all Hawaii routes.
Could this aircraft really serve Hawaii?
The Z4’s mission profile is ideal for medium—to long-haul routes. Hawaii is well-suited in reach, sitting 2,500 to 5,000 miles from most major mainland cities.
In fact, JetZero is positioning this aircraft as a replacement for aging widebodies on routes like these—ones that demand both efficiency and capacity but not necessarily the heft of a Boeing 777.
This could bring new options to Hawaii travelers, who are often squeezed into narrowbody aircraft like the A321neo or 737 MAX today. The Z4’s spacious, blended interior allows for more creative cabin layouts and generous legroom, at least in current theory.
One of our readers, Lee B, put it simply: “Anything to create more interior space than the cattle car single aisle planes.”
Will this jet bring back comfort, or just more of the same?
That’s the big question. While the Z4 design allows for a wide, flexible cabin in theory, what airlines do with that space remains to be seen. Travelers have heard this promise before—and still remember the airline hype about more space that never materialized.
Reader Tom B voiced the concern that “it’s possible that this will be another mechanism to increase corporate profits. Comfort looks like it will be great, but it’s possible that will also be exploited.”
On the flip side, if fuel efficiency does drop by half, that could result in more affordable ticket prices or at least help offset other costs or afford more room. Airlines that fly longer leisure routes—like those to Hawaii—could use that margin to differentiate. Whether they will is an entirely different matter.
Safety and certification are still major hurdles.
The Z4 will face intense FAA scrutiny. This design is radically different from anything currently certified for passenger service. JetZero has said they are working closely with regulators, but no airline will commit in full until the plane flies and proves itself. One reader, MW, echoed this concern, saying “it would take billions to develop. May never get certified because of radical design.”
That’s why the not-far-off 2027 demonstrator flight is so important. If the aircraft performs as expected, JetZero says that commercial versions could follow by the end of the decade or early 2030s.
A quieter, cleaner, and possibly more affordable way to Hawaii.
JetZero fits nicely into a broader trend of sustainable aviation. Its blended wing body minimizes drag and maximizes lift, reducing both fuel use and emissions. For airlines under pressure to decarbonize, that’s another powerful incentive.
That could translate into real-world benefits for Hawaii flights: fewer emissions, lower fuel costs, and potentially quieter cabins thanks to the engine placement and aerodynamic form.
If this aircraft replaces today’s aging widebodies—and bypasses the narrowbody squeeze we’re seeing now—it could reshape the longer-haul Hawaii leisure experience for the better.
When could Hawaii travelers fly this?
Realistically, the soonest you might board a JetZero Z4 is 2030, which might still not be realistic. Between flight testing, certification, and production ramp-up, there’s still a long runway ahead for this.
But this isn’t vaporware, as some have accused Boom Supersonic. It’s a funded project with government and airline backing and a growing public profile. If it succeeds, it could change how we fly and how airlines serve destinations like Hawaii.
The timing also aligns with aging fleet replacements. By the end of this decade, many of today’s jets will be nearing retirement age. The Z4 could be the right aircraft at the right time—if it lives up to expectations.
Would you fly it?
Would you board a jet like this for your next Hawaii trip? What matters most—comfort, efficiency, or a solid seat that gets you there on time? Please tell us your thoughts on this.
And if you’ve flown Dreamliner, A330, 737 MAX, or A321neo to Hawaii lately, how would you compare them to what’s being promised here?
We’ll keep watching this one closely, as we will Boom—because if it delivers on even half its claims, it may soon be flying us over the Pacific.

Having flown many types from super Connie’s, c3s almost all Boings and the air bus. It’s worse than the greyhound bus from the 50s. I am 85 and flew a turbo from SF to Japan. It’s time for newer style planes.
Maintenance on those turbines will be time consuming between flights. Just ask any mechanic who has worked on MD11 #2 tail engines! All good until you have to start opening the cowlings.
As a follow-on to my comment, back in the 1950s Boeing developed a revolutionary design for a USAF tanker contract, known internally as the 367-80; a swept-wing jet powered airplane capable of refueling the then new B-52 bomber fleet. Boeing then took that design, enlarged the airframe, and marketed a new jet airliner, which came to be the iconic Boeing 707. JetZero has established a working partnership with Northrop Grumman, the builder of the B-2 and new B-21 stealth bombers, for the USAF “future tanker project”. That fact alone gives credence to the ultimate viability of the JetZero Z4 as an Air Force tanker and ultimately as an airliner. History may in fact repeat itself !!
I would like to file a lawsuit against the airlines for failing to provide adequate space for the average adult. I’m 5’10” 180lbs. and can’t fit in my seat. Especially when the passenger next to me is larger than me. Legroom is not nearly important as elbow space. I definitely will not be flying anywhere until the seats are widened or I can afford 1st class.
Really hope that Alaska can deliver the gold standard that Hawaiian has done for many years….
This scenario has been played out many times before in the US. It sounds like an investment scam to me. While pandering to investors, a few individuals will take their money and pay themselves lucratively before shuttering the company a couple years down the road. Those individuals will walk away very happy. No regrets.
Right now, the Boeing 777X, an updated version of an existing aircraft can’t even seem to get certified. It’s highly doubtful a blended wing design will be certified for passenger flight by 2030. Tube and wing is very stable. Blended wing, not so much. I’m all in favor of aerodynamic advancements but doubtful you will see this design with passengers in the next half decade.
Articles like this make me chuckle. Airlines are squarely in the business of packing as many seats into the available square footage as they possibly can. cost savings is not going to result in offering customer more room for the same price and is a unrealistic thought. airlines will continue to jam as many seats per square foot as the airplane will allow. That is the nature of the business. The only comfort that will be available will continue to be at a very premium price. If airlines were interested in your comfort they would not be jamming so many seats into each airplane as today. Has anybody noticed how expensive comfort is on international flights? The only caveat here is if the FAA stepped in and demanded only so many seats are allowed per aircraft. I doubt they will do that because airplanes are certified for weight. So airlines are free to do what they want as long as the airplane does not exceed a given weight. We will always be jammed in like sardines
Airlines are profit driven publicly held corporations. There may be dream comfort on the Z4, but it will be available only to those willing to pay. I’ve seen airlines go from 4 to 3 to 2 engine jets that are ever more fuel efficient. These improvements have not turned into comfort or lower prices.
Look at the Z4 and at the tightly spaced jet bridges at airports. Where will the Z4 park? The A380 is limited to certain airports because of its size.
New jet? Possibly. The reality, however, may be far from the dream.
The JetZero BWB (blended wing/body) is under serious consideration by the USAF for a next-gen aerial refueling tanker; thus their financial support. The current KC-46 Pegasus program will provide 179 tankers which are based on the B767 airframe, with a possible follow on order for an additional 50-100 jets. That total number will not fully replace the 376 1960s-vintage KC-135 tankers now in service. So as noted, the door is open for this new concept to see life, at least with the USAF, sooner rather than later !!
The idea of a sleek, carbon fiber, fuel efficient plane with lots of room to move around is exciting. I’ve flown to Europe, Asia, Canada, the east coast, New Zealand and always felt crammed into a small space in a tight row. Not to mention, standing in the aisle to wait to use the lavatory as other people shimmy past me, or just to get out of the window seat to use the lavatory and ask my seatmates to move out of of the way so i can go. I would love to fly on a plane with an innovative design that offers more than “same old same old” expectations. It’s about time that an airline manufacturer will use cutting edge materials to make planes lighter, faster and fuel efficient.
New designs typically mean more expensive for tourist because not many are out there yet. Engines on top. I would question turbulence also in the front flipping upwards and the correction time frame. It might be cheaper as far as fuel for the airlines but lets see where the ticket prices start out.
I am enjoying the Beat of Hawaii, we desperately needed a new voice here in these islands.
You write: “On the flip side, if fuel efficiency does drop by half, that could result in more affordable ticket prices or at least help offset other costs or afford more room.”
I think you meant to say “…if fuel efficiency doubles…”
It also might mean the hotels may raise prices and the end result would be the same total for tourists. Airlines drop prices so hotels grab more at the other side. Hawaii wins and airlines just trying to keep the planes flying full of passengers. Nice thought though. Lets see what happens.
OK, let’s assume that this concept plane actually makes it into production and that Alaska/Hawaii actually buys some. Any move toward more wide body aircraft would be welcome as the current single aisle fleet is dreadfully uncomfortable for long hauls. But the airlines will surely stuff as many seats as physically possible into any new wide body plane . So the promise of passenger space and comfort is truly a dream. Remember when early beautiful 747’s actually had a passenger lounge? That soon changed to just adding more seats. Dream on folks.
Some Continental Airlines’ DC-10’s were configured as “pub flights”, with a lounge and bar up front. Some old United DC-8’s had an economy area in the back with a table surrounded by seats, some facing rearward.
Ah, the glorious days of flying, a bygone era.
Hawaiian Airlines flying this first would be kind of poetic. A small airline with deep roots leading the charge into the future. I just hope the branding stays Hawaiian and doesn’t get swallowed by the Alaska corporate vibe. Some things are worth preserving even as you innovate.
Alaska has already provided funding, as has Delta and United. In fact, United has a pre-order for 200 aircraft.
Fascinating even if not realistic, or at least not yet. All I can think about is how different the takeoff must feel. Also where would the turbulence hit you if you’re basically inside the wing? I’m intrigued but also slightly terrified. I’d still fly it though, because let’s be honest—this design is eye candy.
I bet Alaska/Hawaiian decides to go with the JetZero-900 stretched version as the JetZero-700 burns just about the same amount of fuel as the -900.
The super stretched JetZero MAX-10 will look really amazing! Cannot wait for that one to be built as it’s all about, sustainability, efficiency, and flexibility in the world of making money for an airline.
This kind of leap is exactly what aviation needs next. The fact that these airlines might be part of it is huge—especially after so many headlines have painted the islands as an afterthought in airline strategy. Maybe we’re finally seeing a shift where Hawaii becomes the place to test and showcase bold ideas, not just cut costs.
I had to do a double take looking at that plane. It’s elegant and strange at the same time. I can’t picture boarding it at Kahului or even Honolulu without a complete overhaul of how boarding works. If it actually ever flies to Hawaii, I’ll be watching every update like a hawk.
I’m definitely not convinced. These announcements always make big promises, but we’ve been burned before—remember how the Dreamliner was supposed to feel like “a breath of fresh air”? If the seating still ends up tighter than a subway, none of this matters to me. Show me something that improves legroom, not just fuel numbers and economy of scale.
If Hawaiian Airlines or Alaska ends up flying this thing first, that would be a wild full-circle moment—going from island-hopping workhorses to the most futuristic aircraft in the sky. I remember flying their DC-10 to Honolulu years ago, and this looks like something out of a dream in comparison. My only hope is they don’t cram it full of extra seats just because they can. Comfort should match the innovation.
Total nonsense. First, Hawaiian does not have the money for a new and radically designed airplane as they are barely solvent now
Second we are talking Alaska air as the carriers have now merged. Any new additions to the fleet will be integrated into the entire Alaska route structure
Third, this puppy is a pipe dream and most likely will never be built for a very long list of reasons.
Looks good on paper but not practical for a very long list of reasons
Alaska has already provided funding, as has Delta and United. In fact, United has a pre-order for 200 aircraft. The US Air Force is also on board in some capacity, so….. Not really a pipe dream, yet.
i wsonder what other country will bring this to the skies before the US. bd
Greenwashing. This is merely a scheme to extract money from the government. Specs are bogus as you can not violate the laws of physics. Welcome to America 2025.
Exactly. Pilfer the taxpayers via government/military contract and ransack investor money, then run…and buy your Teslas and properties.
It does look interesting but, this is going to take some time.
