A380
I think Willy Walsh best summed up the A380 this week when talking about leasing some 2nd hand ones, along the line of great aircraft, but not very flexible route wise due to its size. It is perfect for slot restricted airports like LHR, but lets be frank without EK support where would it be?
I was surprised by the Iran Air order for the A380 I can't see the business case, yes flying an Iran Air A380 into Washington or JKF will be putting 2 fingers up to the hawks in congress who doubt that the deal on nuclear containment and the lifting of sanctions is in US interests, anyway lets see how they finance this order given the low price of crude.
I'm inclined to agree with PAXboy the production line will plod on and probably out live the B748-I, but just like Concorde I suspect the 747 program will have made more money for Boeing than the A380 will ever earn for Airbus.
