Hi Koru Flyer,
<<Also one would have thought that QF would keep to the standard that connexions are 4 hours for domestic and 24 hours for international. Where did the 8 hour logic come from?>>
You are right - I think the 4/24 hr rule still applies - I was trying to remember what is was while writing the post. The key issue is that you are not penalised for different routings.
Cheers... Bruce
