Why spend money on improvements before the airplane rolls off the assembly line? There are threats being made by carriers and leasing companies to cancel orders do to late deliveries, weight and design problems.
Airports haven't changed in almost 20 years. Airbus has had the opportunity to design their super white elephant around current airport designs. It is utter arrogance on the behalf of Airbus to assume that airports should be redesigned to accomodate their A-380.
Hey Airbus... heres a thought... instead of giving customers large rebates for purchasing your planes, foot the bill for airport redesigns to accomodate your flying metal cumulus cloud.
