This article gives an indication of some of the maintenance that A380’s required while stored. It obviously adds up to many man hours and it would be good to know if Qantas is paying for this maintenance on all 12 of their A380’s or just the 6 refurbished ones or none of them - that would give a strong indication of what their long term plans are.
