i could atleast concur with how busy it is during july when trying to book flights using FF points.
i booked 2 X business class tickets on FF points from sydney to shannon via mumbai and london with mumbai to london leg in BA's WTP class instead of business. *sob*
paid own way from shannon to london in coach and also had to do a seperate FF booking with alitalia between london and rome.
on the going home trip, we start from milan, to london, to tokyo, to cairns, to brisbane and finally home to sydney.
we've also had cut short of the trip by 2 days as there were zero available FF seats between london and sydney during the third weekend of july 2005.
while on the phone with qantas ff ppl, we tried every one world airline like you, even looked at coming home via the US at one stage.
one thing i noticed while on the phone with qantas FF a few time when trying to make this booking, i've had to prompt the FF staff on which one world airline and route they should look into.
