Engine Differences

Boeing 777:

Primarily equipped with large turbofan engines such as the General Electric GE90, notably on the 777-300ER, and Pratt Whitney PW4000 engines.

Airbus A330:

Utilizes engines like the Rolls-Royce Trent 700, Pratt Whitney PW4000, and General Electric CF6 engines.

Cockpit and Avionics Differences

Boeing 777:

Features a two-pilot cockpit with a fly-by-wire system and advanced avionics. Unique side-stick control system.

Airbus A330:

Also has a two-pilot cockpit with fly-by-wire technology. Uses a conventional control yoke.

Performance and Economy Differences

Boeing 777:

Known for its high efficiency and long range, often favored for transcontinental flights and has a high payload capacity.

Airbus A330:

Generally considered more versatile for medium to long-haul routes with a strong focus on passenger comfort and operational flexibility.

Market Position and Usage

Boeing 777:
