The problems with service on the A380 are completely down to the inexperience of the crew involved. Fact.
Contrast the actions of management at Singapore Airlines with Qantas and you'll quickly realise why QF have problems.
SQ mandate that the crew on their flagship A380 have a minimum of 5 years experience [in the category they operate in]
Not meaning any disrespect to those working on it but the truth of the matter is that QF only had one requirement.
Cheap.
