I just priced out an LONEX starting in MEL for USD$4635, 11 segments. I did this at rtw.oneworld.com. Then I happened to go to qantas.com and click through their rtw link to the same page, which re-opened my existing itinerary and priced it $1500 higher on the base fare: at this point, the price in my already opened tab updated also $1500 higher! I opened a different browser and re-priced it going directly to the tool, and got the original fare (I went through to the cc details page). What on earth is going on there, does this just get added on in some kind of lousy qantas 'fees'?

Unrelated question: I can save about $250 in tax/fees if I fly TAM from Sao Paulo/Rio to London instead of BA. Is there a noticeably different experience in Y? The TAM forums sound pretty negative.

Third question - I tried posting this two days ago and got a message saying "moderators need to approve your post" then it never showed up. How's that work?
