Emirates' first 777-9 is out of the factory. When will you actually fly Boeing's 777X?

The first Boeing 777-9 built for Emirates has rolled out at Paine Field in Everett, Washington. Aviation A2Z reported on September 27, 2026, that the jet was seen in green primer, ahead of a paint job that takes several weeks.

It is a milestone, but not a finish line. The 777X still has no FAA type certificate. Boeing first planned to put the jet in service around 2020. The current target for the first airline delivery is 2027, about seven years late. If you are hoping to fly the world's largest twin-engine jet, here is what we know.

Who flies it first

Lufthansa is expected to be the launch operator, with its first 777-9 due in 2027. That plane carries a full passenger cabin, not a test interior, according to an Aviation A2Z review of the program published October 6.

Emirates is the largest 777X customer by far. Boeing's November 2025 announcement added 65 777-9s at the Dubai Airshow, taking Emirates' 777X order to 270 jets. Emirates president Tim Clark told Reuters in June that he expected the first 777-9 in May or June 2027, as reported by Aviation A2Z. That still depends on Boeing finishing certification.

Other airlines on our site have 777-9s on order too. Korean Air, for one, firmed up 777-9s as part of the 103-jet Boeing order we covered earlier.

What still has to happen

Aviation A2Z lists five hurdles before that first delivery.

The engine. GE Aerospace found a durability problem with a seal in the GE9X engine in February 2026. It traced the cause in April and redesigned the part. Improved seals began shipping in the third quarter. The new seal still needs its own FAA approval, and some engine work could run into 2027. GE says it still expects the engine to support a 2027 entry into service.

The FAA. The test fleet had flown more than 4,800 hours and about 1,700 flights by July 2026. Boeing said then that roughly half of the planned certification testing was done. Approval for long overwater flights, known as ETOPS, was still outstanding. Leeham News reported on October 6 that the 777-9 type certificate is now expected in 2027.

Production jets. Boeing must test aircraft built to the final standard. That includes ground and flight tests of the cabin and connectivity on Lufthansa's first jet.

Old airframes. About 30 early-built 777-9s need changes before delivery. Boeing even took one early jet apart, deciding it was not worth finishing.

Airlines saying yes. Emirates has said it will not accept about 10 of its earliest-built 777-9s, some made as far back as 2019, because of their age and the work they would need. Clark compared planes waiting years for certification to "a can of baked beans," according to Aviation A2Z.

What it means for travelers

For now, nothing changes on your next trip. Every 777 you board is still the older 777-200 or 777-300ER. The 777X will not carry paying passengers before 2027, and the first routes are not public yet.

Boeing says the 777-9 will be wider inside, with better humidity, a smoother ride and more natural light. It also claims the jet will use 20 percent less fuel than the planes it replaces. Those are maker claims. What passengers actually get will depend on each airline's seats.

Lufthansa and Emirates have not confirmed which routes will see the 777-9 first. Both airlines fly big hubs with large lounges. If your trip runs through Frankfurt or Dubai in 2027, you may be among the first to try it.

What to watch

Three dates matter most. The first is the FAA type certificate. The second is Lufthansa's first delivery. The third is Emirates' first 777-9 in service, which Clark hopes for by mid-2027. Boeing reports third-quarter results on October 27, and it may update the 777X timeline then. We will update this story when it does.
