Powered by two General Electric CF6-80E1, Pratt & Whitney PW4000, or Rolls-Royce Trent 700 engines, the 63.69 m (208 ft 11 in) long -300 has a range of 11,750 km / 6,350 nmi, typically carries 277 passengers with a 440 exit limit and 32 LD3 containers.[98] It received European and American certification on 21 October 1993 after 420 test flights over 1,100 hours.[119] The -300 entered service on 16 January 1994.[38] The A330-300 is based on a stretched A300 fuselage but with new wings, stabilisers and fly-by-wire systems.

In 2010, Airbus offered a new version of the -300 with the maximum gross weight increased by two tonnes to 235 t. This enabled 120 nmi (220 km; 140 mi) extension of the range as well as 1.2 t increase in payload.[120] In mid-2012, Airbus proposed another increase of the maximum gross weight to 240 t. It is planned to be implemented by mid-2015. This -300 version will have the range extended by 400 nmi (740 km; 460 mi) and will carry 5 t more payload. It will include engine and aerodynamic improvements reducing its fuel burn by about 2%.[121] In November 2012, it was further announced that the gross weight will increase from 235 t to 242 t, and the range will increase by 500 nmi (926 km; 575 mi) to 6,100 nmi (11,300 km; 7,020 mi). Airbus is also planning to activate the central fuel tank for the first time for the -300 model.[122]

As of December 2020, a total of 779 of the -300 had been ordered, 771 of which had been delivered, with 742 in operation.[2] The 2015 list price is $264 million.[76] The closest competitors have been the Boeing 777-200/200ER, and the now out-of-production McDonnell Douglas MD-11.[123]
