thanks QF WP and Zermatt - will just have to wait and see, i guess!
Things complicated slightly, as Ms Jackit - who will become Mrs Jackit two days before take-off is accompanying me. I had 8 upgrade credits to use, which is why I have only requestd the SIN-CDG leg.
Ms jackit is Qantas silver, so who knows how that will effect my request. Perhaps I should mention at check-in that we are off on our honeymoon...
