You have to admit that the leasing fees paid by SAB to CTB for both MD11s...were incredibly high, the early cancellation of the contract was due of the struggling situation of SN that had no other choice to terminate the leases of 2 aircrafts not required anymore on the restructured network.
Also, CTB's introduction of a code-share (with CAL) flight to FIH in direct competition with SAB was not a clever idea, and I guess SAB had therefore not any problem with their conscious while ending the MD11 contract. SN is not really to blame here I think...
