I recently flew QF879 Gold Coast OOL to Melbourne MEL. I had chicken teriyaki with rice and it was very tasty. The FA was super lovely and kept me very happy with 3 x Lois sparkling wines and lots of sparkling water top ups. It was a points seat too but I felt I was treated very well.
Seedlip do premix cans now which is great to take to parties. Worth checking Lyres out also; they do all of the spirits alcohol free so you can prepare a favourite coughtail (sans ETOH). I like to make up a punch with frozen fruit, soda, splash of juice and a can of ginger beer.
