I'm looking at a DONEx trip where part of the routing is DOH-MEL on QR988 followed by MEL-ZQN on QF177. There's 1h35m between the arrival of the QR flight and departure of the QF flight. This would be purchased through the AA RTW desk. IME QR are unreliable in terms of interlining checked bags on separate tickets.

Am I crazy to attempt a 95 minute international to international connection at MEL?

Is a DONEx ticket across two airlines considered to be separate tickets for interlining bags? Or are DONEx legs all considered to be on one ticket?
