Not shorthaul but as a regular travel I relish those flights for holidays. Mrs SYD and I took QF2 in late Jan and she was horrified to see that from QF Lounge, through first leg and then into QF F lounge in Singapore I'd probably stared down 3 bottles of champagne. I was sober as a judge due to the passage of time and felt like I had reached a Patsy Stone-esque aura by the time the second leg rolled by.
Shorthaul I've managed a G and T and 4 miniatures of Champagne. Think I was flyig to NAP on the evening flight so just over 2h.
I often think of the exploits of royalty such as
PUCCI GALORE and wonder if I'll ever drink my way to such Mucci heights onboard.
