There possibly is a new market for used A380's that current owners want to offload.
But it will be a new type of work -
That maybe a new online platform that has some departure date flexibility until X days in advance, then gets locked in with higher loads.
Tourist promotions for just off season destinations - flight accommodation packages for 800 people.
Cruise ship transfers.
But if there is a new market I believe it will be in the available capacity of +800 and other than RPT type operation, most likely with the flight ancillary to the real revenue obtained.
