I won’t post all mine, when I said I was a nerd about this, I meant it. That flight was probably not long after they switched from Heidsieck Monopole Blue Top (sometimes referred to as Monopoo by some BA frequent flyers) to Castelnau in Club Europe. It was definitely an improvement.
Cantemerle was more likely to be found in First onboard, but did occasionally appear in lounges, so you did well there. BA plumbed some real depths when it came to wine onboard during the pandemic (e.g. unspecified “Spanish red” in Club World), but it seems to be improving again now.
But remember that different wines are served in different lounges, even in the same terminal. I think in Gatwick business you get self pour Champagne, in Heathrow T5 business you have to ask for a glass to be served you.
I’m envious of some of the wines on offer here. I’ve flown club a few times with BA (courtesy of avios points, not work unfortunately) and have found that the onboard wine offer have been marginally better than Yellow Tail levels. Free champagne compensates a little though.
Wine is sometimes better in lounges beforehand, but even then it can be disappointing. I was lucky enough to fly from Heathrow T3 last year and have access to the amazing Cathay Pacific lounge. The wine list was several tiers below the quality of food, spirits and cocktails, unfortunately.
If you’re in T5, the food and wine provision is largely the same in all 3 Galleries Club lounges (T5A North and South, and T5B). It’s a bit better in Galleries First, and if you have Concorde Room access, it’s not worth going anywhere else (wine-wise).
If in T3, agree with post above from @UisceBeatha that it’s better to ignore BA lounges and go to whichever Cathay Pacific lounge you can access.
When I was regularly flying to Chile, Air France gave free champagne in economy on their long haul flights. It was not wise to make as much use of that as I did on a Paris-Santiago (which was something silly like 18 hours) flight, the first time I went.
Yes it’s T5, going to Lisbon. I’m rarely disappointed to discover I’m going from T3 though, the Cathay lounge is very good and I like the views too. I’ll look in on Galleries as i go through, but I’m fortunate to have CCR access so i expect that’s where I’ll end up. I like the champagne there.
Yes, the Qantas international F lounge in SYD is one of my all time favourites too. The modern reality is that the ME carriers and a few Asian carriers are now the leaders in wine offerings, they simply invest a lot more money in it (especially Emirates).
Respect, I’d want a medal and sedative-level quantities of champagne to fly regularly to Chile in economy (especially if working at the other end).
It’s hard to pass on a glass of LPGS, though I do resist for breakfast-time flights.
I was on an academic travel stipend so it had to be economy. I’ve done a fair number of almost as revolting economy flights (Hawaii and Taipei both spring to mind. Taipei was nothing like as bad as it was a Cathay Pacific to HK and then Dragon Air to Taipei. Hawaii was United until the Hawaiian Air portion, so less said the better). Paris - Santiago did used to be the longest flight in the world until these direct London to Perth things started.
Dragonair (latterly known as Cathay Dragon) was ok, it was a regional subsidiary of Cathay Pacific from 2006 to its closure in 2020, and Cathay was a shareholder since 1990.
Talking of Taiwan, I once took a flight in or out of there on a Hello Kitty branded aircraft. Literally everything, including the crew and food, was Hello Kitty branded, a somewhat surreal experience. I don’t recall having wine on the flight, but I doubt it would have escaped the pink and white feline treatment.
