The Boeing 777 is Boeing's twin-engine long-range wide-body and the most successful wide-body airliner in history by some measures: over 1,700 delivered, more than any other twin-aisle aircraft, and the largest twin-engine passenger jet ever to fly. First flown in June 1994 and entering service with United Airlines in June 1995, the 777 was the first commercial airliner designed entirely with computer-aided design (CATIA), the first to receive ETOPS-180 certification at entry into service (allowing transpacific routes immediately), and the first to use a fully fly-by-wire flight control system on a Boeing wide-body.

The family spans seven primary variants. The 777-200 (1995) and 777-200ER (1997) opened the line; the 777-300 (1998) stretched the fuselage by 33 feet to seat 365 passengers; the 777-200LR and 777-300ER (2003–2004) further extended range to 8,555–9,395 nm, making them the world's longest-range passenger airliners until the A350-900ULR arrived. The 777F freighter, derived from the -200LR, is operated by FedEx, Lufthansa Cargo, Emirates SkyCargo, and most major express carriers. The current production model, the 777X, will replace the -300ER through the 2020s.

Both General Electric GE90 and Pratt & Whitney PW4000 / Rolls-Royce Trent 800 engines have powered the family. The GE90-115B fitted to the -300ER and -200LR holds the world record for thrust on any airliner jet engine (115,300 lbf), with a fan diameter of 128 inches that's wider than the entire fuselage of a Boeing 737. The aircraft has the lowest fatal-accident rate per million flights of any wide-body airliner ever built.

By early 2026, more than 1,700 777s had been delivered, with production transitioning to the larger and more efficient 777X. Major operators include Emirates (largest fleet by a wide margin, ~140 aircraft), United Airlines, American Airlines, Air France, Cathay Pacific, Singapore Airlines, and ANA.

For Kids — a shorter, friendlier version

The Boeing 777 is one of the most popular wide-body airliners in the world. It has two big engines under its long wings, can carry up to 396 passengers, and flies almost anywhere on Earth without stopping. The 777 first flew in 1994 and is still being built today — over 1,700 have been delivered.

The 777 was the first big airliner designed completely on computers, with no full-size paper drawings. Boeing engineers used a giant 3D computer system to design every part. When the first 777 was put together at the factory, all the pieces fit perfectly — the first time that had ever happened on an airliner that big.

The 777's two engines are the biggest jet engines ever built. The General Electric GE90-115B engine has a fan in front bigger than the body of a Boeing 737 fuselage. That fan can pull in 1.3 million cubic feet of air every minute — enough to empty a swimming pool of air in seconds.

About 60 airlines fly 777s today. Major operators include Emirates, United Airlines, Air France, ANA (Japan), British Airways, and Singapore Airlines. The newest version (called 777-9 or 777X) has folding wingtips that fold up when the plane is on the ground — so the very long wings still fit at airport gates. The 777X first flew in 2020 and will enter service in 2026.

Fun Facts

  • The Boeing 777 was the first airliner designed entirely on computers — no full-size paper drawings.
  • The 777's engine fans are bigger than the body of a Boeing 737.
  • About 1,700 Boeing 777s have been delivered since 1995.
  • The 777 can fly more than 8,500 nautical miles non-stop — far enough to fly from New York to Singapore directly.
  • Some 777s carry up to 396 passengers — almost as many as the A380.
  • Air New Zealand once flew a Boeing 777 around the world non-stop, just to show it could be done.
  • The new 777X has folding wingtips — the very long wings fold up so the plane still fits at airport gates.

Kids’ Questions

Why is the 777 so popular?

The 777 hit a perfect sweet spot. It carries lots of passengers (300-400), flies very far (8,500 nautical miles or more), uses only two engines (saving fuel and maintenance costs vs four engines), and is reliable. For airlines that want one airplane that can fly almost any long route, the 777 is the answer. It can fly Tokyo to New York, London to Sydney, or São Paulo to Frankfurt — all routes that used to need stops. The 777 made long, non-stop flights affordable for normal travelers.

Why folding wingtips on the 777X?

The new 777X has very long wings — over 235 feet wide. That's wider than most airport gates can handle. So Boeing designed the wingtips to fold up just before landing, like a folding pocket knife. The wings extend back to full width for flight. On the ground, the folded tips make the airplane narrow enough to fit in regular 777 gates. It's the first time wingtip folding has been used on a passenger airplane.

Frequently Asked Questions

How many passengers does a Boeing 777 carry?

The 777-200 typically carries 314 passengers in three-class seating; the 777-300 carries 386; the 777-300ER carries 365–396 depending on configuration. High-density single-class layouts can push capacity above 440 seats.

Boeing 777 vs Airbus A350: which is better?

The A350 is more fuel-efficient per seat and uses a composite airframe; the 777-300ER is larger and has lower per-seat capital cost. The 777X (in production from 2026) closes much of the efficiency gap. Most major airlines operate both, choosing by route mix and fleet commonality.

How far can a 777 fly?

The 777-200LR holds the absolute airliner range record at 9,395 nm (over 17,000 km). The 777-300ER manages 7,370 nm; the standard 777-200ER reaches 7,065 nm. The 777-200LR has flown the longest non-stop scheduled flight ever recorded — Hong Kong–London via the Pacific in November 2005.

What replaces the Boeing 777?

The 777X family replaces the 777-300ER and -200LR with the larger 777-9 and longer-range 777-8. The 777X uses new GE9X engines, composite folding wingtips, and a 787-derived cabin.

How many Boeing 777s have been built?

Over 1,700 777s of all variants had been delivered by early 2026, making it the most-produced wide-body airliner of all time by a comfortable margin. Production continues at lower rate as the 777X ramps up.
