I would be doubtful for this but just noting that unless things have changed you need to be flying F or J to access the (rather nice judging from my fairly brief visit) QR lounge, regardless of OW status (at least on other OW airlines, unsure about QR status).
Thanks to blackcat20 and JessicaTam for organising. Great night and an overdue catch up with old friends. Also good to meet a new one or two. At the risk of sounding lik Mr Grumpy, it would have been nice too see what I was eating. :p
