Airbus A330-300 vs Airbus A330-900neo

The Airbus A330-300 and A330-900 are the same aircraft two decades apart. The A330-300 entered service in 1994: a 63.7 m twin seating around 277 in three classes, with a 60.3 m wing and a choice of General Electric CF6, Pratt & Whitney PW4000 or Rolls-Royce Trent 700 engines, flying up to about 6,350 nautical miles in its later high-weight versions. More than 750 were built, and it remains one of the most common widebodies on medium- and long-haul routes worldwide. The A330-900, the A330neo, entered service in 2018 with the same fuselage but a new wing of 64 m span with composite Sharklet tips, Rolls-Royce Trent 7000 engines, a new Airspace cabin and about 14% lower fuel burn per seat, with range stretched to around 7,200 nautical miles.

Airbus kept the A330-300's cockpit and type rating, so a pilot moves between the two with a short course, and airlines such as Delta, TAP, Lufthansa and Cathay Pacific that fly both treat them as one fleet. The neo's case rests on fuel and range; the A330-300's on price, with hundreds of airframes on the used and lease markets at a fraction of the neo's cost, which keeps it attractive to leisure and secondary-market carriers.

Passenger experience

The cabins share a cross-section, so economy on both is usually the A330's 2-4-2 with seats around 18 inches wide and a window-and-aisle pair on each side. The A330-900's Airspace cabin brings larger overhead bins, a new ceiling and sidewall design, LED mood lighting, a quieter sound level and, on many aircraft, a newer generation of business seats. A330-300s range from freshly refurbished to tired, depending on the operator and the airframe's age. The neo is noticeably quieter behind the wing thanks to the Trent 7000's higher bypass ratio. On either, the side pairs ahead of the wing are the best economy seats and the rows beside the rear galley the ones to avoid.

Which to choose

For an airline the neo is the better aircraft wherever it can be afforded; the A330-300 is the better deal when capital matters more than fuel. For passengers the difference is a newer, quieter cabin on the neo and the same comfortable layout on both, so an A330-300 with a refreshed interior gives up very little.
