Well that would be stupid and pointless. The 380 has an UNFOLDED and UNFOLDABLE wingspan of 261ft plus........................... And it seems to fit into many airports now.
Seems that a few people don't understand the problems the A380 has caused and is still causing. At LAX for example. The A380 causes a lot of congestion when this aircraft moves about this airport, because of wingspan. Unfortunately, not all the grumblings are evident on the pilot/ATC airwaves.
The amount of infrastructure changes required for smaller airports such as Sydney can be prohibitively expensive: New aerobridges, greater spacing between gates, taxiway widening (and subsequent repositioning of roads on the margins of taxiways), new servicing vehicles to be able to reach the A380's upper deck doors (catering on 747s is often done via the main deck doors, with the Upper Deck being serviced by the aircraft's cart elevator), etc.
