I saw on SQ's website that you can upgrade on all fares except V,Q,G,N using KF points.
aussieinsf: travel.com.au told me they will have no problem sending me the tickets. They told me i have to send them a copy of my credit card and driver's license. I am really not that comfortable sending that by mail or anything. Do you think it's better i just spend a day in SYD to pick up the tickets before starting that trip?
