I flew first class just one time to Europe, 1972, the late lamented Pan American Airways, when air travel was part of the vacation. We had a full course menu to choose from, a wine cellar, and a lounge up a spiral staircase where I watched the sun come up over the last of the Empire.
On the drink list was a libation called "The Silver Slipper" champagne and Guinness Stout, not to be confused with more common beers. I remember it to this day, delicious! But a memory probably clouded by the luxury of First Class accommodations when flying was also a luxury.
I will spare you my harsh opinion, laced with obscenities of course, of modern day "flying."
