The difficulty is that, apart of course from Emirates, the A380 purchasers have only bought the aircraft in relatively small numbers. If it's expanded, particularly in cabin size, those same carriers would be the principal market, and they wouldn't want to have two small subfleets that were not interchangeable on their routes. There does appear to be no secondhand market. Although British Airways, for example, might be interested, it would really only be maybe a dozen more as a top up, and then they would end up with two different fleets.
