And, the "light" range of the A318 is 2000 NM tops.
Where did you find this number?Airbus
quotes a 3100nm range with max. pax load...
The A318 is available with a variety of different maximum take-off weights (MTOW) ranging from a 59 tonne, 2,750 km (1,500 nautical mile) base model to a 68 tonne, 6,000 km (3,240 nautical mile) version.
The lighter weight of the A318 gives it an operating range 10% greater than the A320, allowing it to serve some routes that the A320 would be unable to: London-New York, Perth-Auckland and Singapore-Tokyo, for instance.
So maybe you got old info, and obviously BA would have the longest range version (theirs are actually brand new)
