It has been a long time coming.
The much delayed first Boeing 777X should enter service with Lufthansa sometime in 2023.
Given the amount of drama surrounding the 777X program, it sometimes feels like the
plane has been around forever when, in fact, it has barely landed.
The 777X is shaping up as Boeing's successor to the popular 777-300ER aircraft.
But it's nearly 18 years since the first 777-300ER took to the air.
Clearly, there are going to be some differences.

And in today's video, we are going to discuss “777x vs 777 | WHAT'S THE DIFFERENCE?”
So without any further ado, Let's begin.
The Boeing 777-300 is a long-range, twin-aisle, twin-engine jet manufactured by Boeing, the
American aerospace company.
Often referred to as the “Triple Seven”, it was the world’s first commercial aircraft
entirely designed by computer.
Its visible features include super large engines, low-hanging landing gear, and a blade-shaped
tail cone with a relatively narrow tailfin.
By the time the 777X enters service, Boeing will have stopped producing the 747, the first
time since the 1950s that Boeing will have no four-engine jets in production.
It will still be at least two more years before any paying passenger can step foot onboard
the 777X.
Boeing currently plans to make the first delivery to a still-unidentified customer in late 2023.
The first big difference between the 777X and the 777-300ER is the wingspan.
Both 777X variants have a wingspan of 71.8 meters, roughly 15% bigger than the 777-300ER's
wingspan.
Because the wingspan is so huge, the wings' actual ends need to fold upwards to allow
the plane to use normal gates.
This new wing design needed FAA approval as it is technically a new class of airplane.
But these innovative wings will give the 777X greater lift and less drag.
This helps make 777X more fuel-efficient than the previous generation 777-300ER.
Depending on who you ask, the 777X is 10-15% more fuel-efficient than the 777-300ER.
That percentage may not sound like a lot, but every dollar counts in the cutthroat airline
industry.
While the fuselage materials aren't that different from the standard 777-300ER, the wings are
almost completely made of composite materials not necessarily available two decades ago.
The first 777 took to the air in 1994, and it has since become a mainstay of airlines
on every continent.
You can find it doing domestic runs in Japan with 500 passengers in high-density seating,
shuttling between London and New York with American Airlines and British Airways, or
doing 16-hour ultra-long-haul flights.
It may not be as loved as the 747, but you have a very good chance of finding yourself
on one: the three major legacy airlines in the U.S. all flew it at one time or another.
The 777X engines are also worth noting.
Boeing is using a GE9X engine with a 132" fan.
Despite quite a few problems getting the engines into service, the FAA has recently signed
off on them.
The GE9X engines will be the largest and most powerful commercial aircraft engines built
to date.
In addition, GE says that they are the quietest engine ever built by them, falling within
8 dB of Stage 5 aircraft noise standards.
Compared to earlier versions of the 777, emissions will be cut by nearly 30%.
All up, these engines will consume significantly less fuel than the older GE90 engines used
on 777-300ERs.
The 777X engines will also be much quieter.
Up in the cockpit, pilots will notice better technologies such as turbulence detectors
and improved autopilot systems.
For passengers, the big differences will be larger windows, a wider cabin, new lighting,
and new cabin architecture.
British Airways took part in the design of the aircraft with Boeing and is today one
of the world’s largest operators of the type.
The Boeing 777 has emerged as a best seller for long haul commercial aircraft thanks to
its excellent fuel efficiency and cabin comfort.
