Does anyone know if DL still offers interline Global Fares for OAL staff? These are for employees of other airlines and permits space available travel at set rates from US to DL destinations worldwide, for example US to Asia at $450 with taxes included. These are not ZED fares.

I have a flyer from 2007 and was wondering if the offer is still valid. I have checked with my Staff Travel department but haven't gotten a response. Thanks in advance for your help.
