Per the most recent spreadsheet info -
Oneworld Explorer 4-continent, economy - bought in UK GBP 1389 or 1449 (depending on month purchased.) Bought in France, EUR 2349 (around GBP 1628.) Both plus tax and fuel surcharges.
Star Alliance, 29,000 mi economy bought in UK, GBP 1409; in France EUR 2399 (~GBP 1647.)
The OW Explorer would allow more flexibility and lots more travel if she wants to do so - internal flights in Oz, Asia, N. America, etc. 20 flights max.
