Estimates of Daily Visitors to Qantas Domestic Lounges

This is a long shot question...

I'm not sure that I've seen any figures ever published but you could take a stab at working it out the long way, at least for the business lounges. Count the number of Qantas domestic flights out of SYD T3 each day; work out the split between Boeing 737s and Airbus A330s; count the number of business class seats in each, and assume perhaps 80% occupancy; but then comes the 'rubbery figure' of how many Platinums flying economy would be on those flights as they also have access to the business lounge. There's really no way to estimate that. Qantas has never published a breakdown of its frequent flyer tiers so this is where you'd come unstuck. Trying to work out the same numbers for the Qantas Club lounges (QFF Gold plus Qantas Club members) would be even more of a nightmare.
