The whole reasoning behind the a380 was that Airbus forecast the airline industry moving more towards a hub and spoke system, and to help alleviate congestion at major airports such as LHR. I agree that the 747-8 has been a bigger failure than the a380, but this is where i think the airline industry has failed. Boeing forecast more point to point services which the slightly smaller 747-8 would better serve. BA is looking at more a380's because LHR is congested. What I am suggesting is that the a380 is too big an aircraft for BA and that the economies of scale of having a larger number of slightly smaller aircraft is the way for them to go. That and perhaps make use of LGW and MAN airports for long haul operations.
