The main reason for me using an FFP is for the status. The points we tend to use for upgrades on a paid Y or J ticket. Seems that QF is best for status at the moment.
My company has a very generous travel policy but I think even they may balk at paying 2-3 Club Europe fares a week and will just shove me in Y, so I need status for lounge access and premium check-in for the main part. Thanks for your help.
