Lucky you. I’ve never flown first class. Can’t afford it. If the first time I ever get the chance to fly there, I for one will not be happy if there’s an obnoxious kid (or adult) within earshot.
It’s not fun in economy either, arguably less so, with even less space. I fly about 50 segments a year, including 3-4 r/t international flights to europe. The flights to Europe or Asia in biz class are very nice with the lay down flat seats but after a brief period of being “cheap” at $2-$3k r/t, they are back to $10k+ now - more than before.
