All my family members are adults, so no not generous. You might be getting confused with the child policy, which is also generous on Qantas.More access for families? VFF is generous enough with people guesting other airline pax into the lounge without flying VA. They should tighten this up like QF are doing.
It's total mayhem in the lounge when delay and disrupts hit and I wonder how many people in the lounge at those times are guests of a SG/WP or have been guested in prior and make it their home.
You may also miss the point that VA lounge are almost all domestic. Qantas also allow guess who are flying on other airlines in domestic lounges.
