UPS can no longer subcontract flying in international operations if "not economically feasible." (Article 1.D.2.a) (Art. 1.D.3.)

I'm not a lawyer, but it seems that "if not economically feasible" is pretty vague language.

For the first time, UPS has legal obligation keep IPA international flying free of cabotage unless there are legitimate reasons. No obligation existed before. (Art. 1.D.2.c.)

Again, "unless there are legitimate reasons" ie (its cheaper)?

Just these two statements seem to have holes big enough to drive several big brown trucks through.
