This flight was just jammed, though, not a single seat free. So I reckon my chances of a better seat on a Basic fare were limited at best. Not complaining, though, it was totally bearable. And traveling next to normal Russian people, even tough guys with tattoos and so on, was a civilized and quite pleasant experience. Might not have been the case in the US or the UK. Shame (but maybe just as well?) they don't serve alcohol in Economy on S7.
