EDTO routes often offer a time advantage, PER-MEL v.v. springs to mind. PAE was doing this for a time for QF but non-EDTO. Was this a possible factor in them losing that work?
I think you’ll find the QF freighters are EDTO as are many other freighters operating in Australia. I can’t see the operators going to that expense if
you don’t need EDTO for freighter operations
