I'm trying to get a quote for the below routing but no-one at CX/AA seems to be able to give me a straight answer if this is a DONE3 or DONE4 tix.

ICN-NRT-(MEX)-SCL-IPC-SCL-GIG-SCL-MAD-DME//SVO-HEL-ICN

The issue I am having is NRT-(MEX)-SCL leg where MEX is only a transit stop between the JL/LA flights. Hope someone could clear this up for me as the price difference between DONE3/DONE4 is rather large.

Thanks,
