When you think about posting airline facts here, keep in mind that this is a discussion group for frequent travelers. Nearly all of us have taken over a hundred trips by air. A substantial fraction of us take that many per year. (My 2+ million miles on one airline and 1+ million on another probably don't put me in the top half of active members in that regard.) Facts that would be novel and interesting to the general public may well get an "Everyone knows that" yawn on FlyerTalk. That's not to say you shouldn't post, but that you have to take your audience into account when you post.
