All A346 have been or are in the process of reactivation, the A343 will reach the end of their cycles soon. The B789 are a replacement for the A343, the A359 replace the A346 and eventually the B779 is supposed to replace the B744. Boeing is probably paying for the reactivation (& the higher fuel burn) of the A380/A346 and some of the leasing costs of the sprinters to cover the delay of the B789 & B779.
