Lu, regarding the insurance aspect. The passenger legal liability insurance of most airlines will be thinly spread around the world insurance markets you can be sure of that! Those operating the A380 will be no exception. The premium payable is calculated on Revenue Passenger Kilometres, (RPK), travelled per annum for the airline concerned. The original placing of the insurance will be shared among many, many underwriters and then re-insured out a few times as well, this is so designed that when a disaster comes no one goes bust. Airlines with USA exposure have to pay a higher premium based on the extent of that exposure which has to be declared to underwriters when the policy is placed or renewed.
