Really. The single flight (only done once) you refer to was the delivery flight of an empty 747-ER from London Sydney done as publicity stunt (11,185 nautical miles), not a commercially scheduled flight with passengers. If you lookup the aircrafts' ranges, the 747-400ER's max range when loaded with passengers is 7,670 nautical miles. The great circle distance Heathrow to Sydney is 9188 nmi. Heathrow to Perth is 7829 nmi. Airbus 350-500 max range of 9980 nmi. Newark to Singapore is 8285 nmi.
