Only BA and CX serve JW Blue these days. AA does have some pretty good wines which vary by route and season, and my last 2 flights have had the 1996 Perrier Jouet Belle Epoque champagne (which is an excellent vintage, Dom quality and now sells for USD 150 a bottle); so some UK flights also get it. Breakfast has steak and an omelette (fresh eggs disappeared years ago, though CX still has it).
