Boeing 777X Nears Certification, Could Fly Passengers By Mid-2026

Boeing 777X Nears Certification, Could Fly Passengers By Mid-2026

35

Boeing has had a rough several years, but could things finally be starting to look up for the aerospace giant?!

Basics of the Boeing 777X certification woes

For those not familiar, the 777X is Boeing’s newest version of the 777. It will come in two variants — the 777-8 and 777-9 — and the planes are more fuel efficient, longer range, and larger than existing 777s (and larger than 787s, which are also popular).

Boeing 777X variant specs

With there clearly not being a market anymore for production of planes like the A380 and 747-8, this will likely be the biggest new aircraft we see manufactured for the foreseeable future (or possibly ever, given that future focus on aircraft development will likely center around efficiency rather than size). There are currently over 500 orders for the 777X, and many airlines are relying on the plane for fleet renewal.

The challenge is, Boeing has had major issues getting this plane certified. The 777X program started back in 2013, and the plane was supposed to enter passenger service in 2020. Currently, the expectation is that the plane will begin operations in 2026. What has caused this six year delay?

Well, a lot of factors, ranging from production issues, to engine issues, to certification issues, to the pandemic, to striking workers, to increased government oversight of Boeing’s work. It just seems like Boeing has been unable to catch a break, and with each passing year, the plane’s timeline has been pushed back by an additional year. Could that luck soon be changing, though?

Boeing 777-9 test aircraft

Boeing 777X enters next certification phase

As recently reported by Jon Ostrower at The Air Current, the Federal Aviation Administration (FAA) has cleared Boeing to begin the next phase of its 777-9 certification, which focuses on system demonstrations.

Type Inspection Authorization (TIA) is the fourth phase of the certification program for the plane, and it marks one of the last steps before the aircraft can be certified. So this is material progress with the plane’s certification.

Furthermore, in the coming days, Boeing is expected to make its first maiden flight of a 777X in nearly five years, which will be Boeing’s fifth test aircraft. Again, this is huge progress.

Currently, the hope is that the jet will be certified by the end of 2025 or early 2026, with the first plane entering passenger service around the middle of 2026.

Of course anything can still happen before the plane is certified, but for the first time in years, it actually feels like progress has been made. This is also the first time since the start of the pandemic that I’ve felt like “oh, maybe passengers will actually be flying on this plane within the next year or so.” Or maybe I’m being naive, and forgetting that we’re talking about Boeing.

Lufthansa will be the Boeing 777-9 launch customer

Why passengers should care about the Boeing 777X

There are currently well over 500 orders for the 777X, so the plane is popular, though not as popular as the A350 or 787, which are lower capacity while still being long range and fuel efficient. Emirates is the single biggest customer for the 777X, as the airline has 205 of these jets on order, and is using these to replace Airbus A380s, as those planes retire.

However, airlines like All Nippon Airways, British Airways, Cathay Pacific, Lufthansa, Qatar Airways, and Singapore Airlines, are also counting on this jet for fleet renewal, all with plans to make this their flagship aircraft.

As passengers, we should be excited about the 777X for two reasons:

  • Many airlines have been forced to keep older planes around due to the 777X delays, so once the plane starts flying, we’ll hopefully be on quieter, more modern, and more fuel efficient aircraft
  • Many airlines plan to introduce new flagship first and business class products on the 777X, and there should be some pretty spectacular new seats introduced

For example, Lufthansa has blamed much of its new Allegris cabin woes on delays with the 777X, since those seats were initially supposed to debut on that aircraft. That’s not exactly cutting edge, though we should see some stellar products introduced on other airlines.

For example, airlines like All Nippon Airways, British Airways, Cathay Pacific, Qatar Airways, Singapore Airlines, etc., all plan to introduce brand new first class products on this aircraft. Perhaps the most anticipated is Cathay Pacific’s new first class.

While we don’t officially know anything yet, we have reason to believe that the product will be known as the “Halo Suite,” and that it could revolutionize first class as we know it. This product could be based on Paperclip Design’s Peacock Suites concept.

As an airline product geek, the 777X is the single most exciting plane we’ve seen since the A380, in terms of impact it will have on the onboard product.

Bottom line

After years of struggles, certification of the Boeing 777X is making material progress, as the aircraft is entering a new phase of testing. This will also see Boeing operate a maiden flight for a new 777-9 test aircraft for the first time in around five years.

The current plan is for the plane to be certified by the end of 2025 or early 2026, and enter passenger service by the middle of 2026. I sure hope this timeline sticks, as there are so many new onboard products that we should see introduced on this aircraft.

What do you make of the prospect of the Boeing 777X finally being certified??

    When I was a little kid, my grandpa would tell me about the 777x being certified….he’s been gone chit awhile but I still have hope.

  2. Robert Guest

    I am not a Boeing hater, but very much aware of what they did in regards to the 737 MAX. I think it is great that Boeing is using the folding wing. It is a very proven technology of aircraft carrier planes for many decades. But, let's not forget, the 777X is basically an extended 777 which was designed in 1989 (36 years ago). The fuselage is aluminum not composite. If any of you see similarities to what happened with the 737 MAX, I believe you are correct.

  3. Mike Guest

    Yeah I'll be waiting a few years before I step on one of these.

  4. Joe D Guest

    The plane first flew in 2020 and it's taken another 5 years for it to fly again?? With modern technology how is this even feasible. ChatGPT didn't even exist 5 years ago. Are there any other Boeing designs that have taken this long in the modern era? Makes you wonder why this is called 777 and not 797 or something new.

    1. Dusty Guest

      Well, a couple years of progress were essentially lost due to the COVID epidemic resulting supply chain breakdown, and for Boeing specifically being under the microscope following the MAX debacle.

      And I'll just point out, once you realize that ChatGPT is just a text generator running on stupidly powerful and expensive hardware, it's far less impressive. It's not "intelligent".

  5. derek Guest

    What happened to the days like when the 747 was designed and built in 5 years? Are we stupid? Are we lazy? Were they sloppy and approved anything in the 1960's?

    1. Dusty Guest

      The biggest reason is that things were just less complicated back then because aircraft weren't as efficient. Modern aircraft use a lot of carbon fiber and other composites in their frame and skin in addition to aluminum alloys used in the old days for weight savings. Today's engines especially require far more precision than they did in the '60s due to lighter materials, higher reliability requirements, and higher thrust outputs. You also have software in...

Today's engines especially require far more precision than they did in the '60s due to lighter materials, higher reliability requirements, and higher thrust outputs. You also have software in the mix now, with onboard flight computers instead of fly-by-wire controls to allow quicker training of new pilots.

      Beyond that, you also have far more regulation now, much of which is the result of issues experienced with older aircraft types that either caused or contributed to catastrophic failures. Think Aloha 243 or United 811, or to go older the issues with the De Havilland Comet. Pretty much everything we learned as a result of an air disaster became a regulation that manufacturers had to follow. This is a huge part of why flying is as safe as it is today.

    2. ImmortalSynn Guest

      No, we're more crash averse.

      People forget, a lot of the lessons learned from these aircraft that were designed+built+tested+flown in a short time (especially the 1960s and 1970s), came from multiple crashes after they were inaugurated. That began to change in the 1980s, and but lead to significantly increased design and testing times. More so into the 2000s, 2010s, and today.

      The first 787 rolled out 18 years ago, yet only now has had its first crash, which is looking to be completely pilot-caused and nothing to do with its design.

      The first A350 rolled out 12 years ago, and has never had a crash.

      This is what the flying public now expects. You saw how badly people FREAKED OUT when the American Eagle and Delta Connection crashes happened in such close timing, this year, despite neither really having anything to do with the design of the aircraft.

    What will fly first? LH's 777X or DL's new A350-1000? Bookies open at 11am....

    1. Tim Dunn Diamond

      it's most notable that no US airline has ordered a new generation large widebody other than DL's 35K

    2. ORD_Is_My_Second_Home Diamond

      Because real airlines like United and American, and not crop dusters like Delta, feel their needs are being met by the 787 and are avoiding garbage like anything from Airbus. Only Delta feels the need to get into a willy-waving contest due to their inferiority complex.

    3. hexagonsarethebestagons New Member

      Characterizing the 359/35K as "garbage" is a seriously hot take. While the 787 is certainly a nice plane (and one I prefer over the 777/767 handily), the 350 is a really refined experience even from the 787. I was blown away at how quiet it was and how little cabin vibration there is, to the point that I really didn't feel wearing noise cancelling headphones was necessary—not exactly true on the 787.

    4. Tim Dunn Diamond

      and, most significantly, Airbus has been delivering A350s to DL according to the terms of DL's contract. AA and UA could only wish Boeing would do the same.

      none of which changes that the A350-1000 is the most capable and efficient widebody in existence right now. AA and UA have nothing to compete with it and the best they can do is take another 20-30 seats off their 787s in order to hope to do...

      If the ~315 seats on DL's 35Ks and that DL is getting the highest capacity fuel tanks and takeoff weight, the DL 35K will easily be an 18 hour plane, something no Boeing will be able to do with anywhere 300 passengers for years - until they can get the 777-8 in the air - and after the massive backlog of larger but less capable 777-9s.

  7. Dusty Guest

    Won't hold my breath, but I do hope they manage to meet the 2026 timeline. Airbus does actually need competition, I'd like to think Boeing actually learned their lesson from the MAX, and aside from all that I'd just like another big widebody to look at while I'm planespotting around the terminal before my flight.

    In the short term any individual company is going to wax and wane, and while the MAX issues were a...

    In the short term any individual company is going to wax and wane, and while the MAX issues were a legitimate debacle and it's enraging that nobody was actually held accountable for it (hell, the CEO got a sweet golden parachute deal), that doesn't mean I want Boeing to continue to fail.

    1. UncleRonnie Diamond

      Indeed Dusty, checking out those folding wingtips in action will be sweet.

    2. D3SWI33 Guest

      The folding wingtips are a design flaw that has potential to create maintenance problems down the road.

    3. UncleRonnie Diamond

      Like I said, watching crews struggling to get both winglets down during taxiing will be fun to watch from the terminal. Not so much from inside the hull.

  8. Barry Guest

    Is anyone here familiar with the certification process and can say what are the next steps after this current step, and what this step (and any further steps) involve?

  9. AeroB13a Guest

    Same old, same old rhetoric from a desperate aviation company who has seriously lost its name.
    As the Boeing Defence workers are on strike over pay issues, how long will it be before the rest of the Boeing workers follow suit?

  10. Tim Dunn Diamond

    Boeing needs a win and the 777X has had its share of certification disasters not the least of which was blowing out a door frame during pressurization tests.

    Boeing has built dozens of 777X airframes that are destined for airlines but will need to be reworked before delivering to airlines but Boeing's cash flow could increase fairly quickly as the 777-9 starts being delivered.

    of course, Boeing still can't get out of its own shadow...

    of course, Boeing still can't get out of its own shadow with the MAX 7 or MAX 10 which has far more orders than the 777X.

    1. Opus Guest

      A lot of the 777X issues have been solved

      And the fact you brought up the cargo door blow out during the 150% stress pressurisation test shows me you’re not actually researched what has been going on because that problem was solved 3 years ago.
      .

    2. Tim Dunn Diamond

      the pressurized door blowout IS part of the 777X certification process. the fact that you want to sweep it under the rug says volumes about you and not me.

      I want to see Boeing succeed as much as anyone -esp. since the 777X is entirely bringing foreign revenue into the US but no one, including the FAA, is going to forget that Boeing has bungled design and manufacturing of its product for a couple of...

    3. dx Guest

      This is basically correct. As of now, every airline and the FAA rightly views new Boeing planes from any line as "Verify before you trust anything", and rightly so.

    4. AeroB13a Guest

      Well articulated Tim.
      Many want to believe in Boeing, some even swallow the corporate propaganda, however, the thinking person knows that they will not be so easily fooled by the company spin.

  11. Mike O. Guest

    Once the a/c is certified, I can see more orders. But it'd be nice to see a new customer for a change aside from Lufthansa.

    1. Opus Guest

      Korean, Ethiopian, China Airlines have all signed up in the last 12 months.

    2. Mike O. Guest

      All customers you've mentioned have had 777s already. I'm talking about a new 777 customer. Lufthansa and Swiss are the only recent new ones I can think of as well as Mahan Air, but that's a story for another day ;)

    3. Opus Guest

      Doubt you’ll see more non 777 customers come on board. If you couldn’t handle a 300ER you’re definitely not going to be able to handle a -9

    4. Mike O. Guest

      True. The only major holdout of the 777 would be Qantas who ironically was part of the design process of the 777. But we all know how that went.

    5. itsamoeder New Member

      Swiss is flying 777 as well as Austrian, so it's not really new in LH Group

    1. Opus Guest

      Other than the well define certification issues which have now been resolved made obvious by the progress the aircraft is making. Do you have any other meaningful concrete evidence to explain why you think the aircraft won’t be in service next year? Or you’re just taking a surface level approach based on the previous delays without not actually understanding why they happened? Most people do because most people are actually uninformed.

  12. chris w Guest

    @Ben with 500 frames on order, how quickly realistically will Boeing be able to build these aircraft? Will more than two per week be ready for delivery in, say, 2027 would you guess?

    1. NSS Guest

      Yeah, that's the big question. And are they building them before certification with the potential to have to retrofit fixes, like they had to with the 787? I just don't see this being fast.
