With an xGLOBnn you can backtrack
within a continent.
xONEx's tend to be preferred over xGLOBnn's by FTer as they allow for longer routings and hence more FF miles and Status.
One big difference (aside from being distance limited) is the xGLOBnn allows travel on QF codeshare services on PX (Air Niugini), TN (Air Tahiti Nui), VN (Air Vietnam), SA (South African Airways), NF (Air Vanuatu), SB (Air Caledonie) and JQ (Jetstar [not for ex Oz itineraries]).

This is correct for a xGLOBxx. (with an xONEx, you
can transfer in Europe as long as the travel is to/from or via Ghana, Nigeria, Kenya, Uganda or Tanzania)
