1. The SIA A340-300 are still in the posession of SIA. If SIA isn´t able to sell them Boeing has to take them.
2. At the moment it seems likely that MAS will take some or all A343 from SIA. See another post from me.
3. Other possible buyers for the A343s: Cubana, AOM, Cathay Pacific.
4. Please stop telling bad things about the A340 or label it as you personal opinion. Thanks!
