First of all, are the four A330-300s and six A340-300s ordered by SAS Scandinavian intended to replace their current B767 fleet? Where will the new planes arrive?
If yes, I reckon they would opt for the A330-300s to fly into South East Asia due to its economic over A340s which is designed for ultra long range flights like HKG-JFK or something.
CPH-BKK currently is flown by the B767. Does the A330-300 have the enough range to fly CPH-BKK? The range that Airbus said the A333 has is some 10,500km. I believe CPH-BKK doesn't exceed the latter but people say that when airliners are fully loaded they are incapable of flying the range promised and if this is the case, does that mean the A340 will fly this route?
When the A330 series and A340 series are fully loaded, is their range on their technical sheet achievable?
I really appreciate your response and please forgive my ignorance and correct my mistakes if any.
