If you'll permit me to cheat a tad perhaps then I claim:

Baggage Allowance Changes - It's Official

I also recall on the day the August security scare kicked off last year I was in Finland so had a 2hr headstart on the UK board and began a thread with a news alert. A couple of other threads appeared almost at the same time and eventually they all got merged...my thread title was retained but TEX277 got the OP. Well, let me tell you, that upset me more than the chaos Oh well, I'll settle for 34,855 instead of 36,312...and save TEX277 the trouble of finding what must surely be his top viewed thread

Also interesting that a retrospective filter seems to apply too on old threads. When I began: http://www.flyertalk.com/forum/showthread.php?t=539976 it was brought to you by the letters 'W', 'T' and 'F'. Now they're censored out. Less surprising is the subject of that thread means it could have been posted pre- or post-upgraded filters, for (continued) shame
