First things first - it's not a rumor, it's pure speculation. But: there is this article in Polish (http://news.money.pl/artykul/pierwsze;dreamlinery;w;europie;trafia;do;lot-u,200,0,631752.html#utm_source=rss&utm_medium=rss&utm_campaign=rss) that says, that LOT will take three first Dreamliners on NOVEMBER. But, according to this post on All Things 787 (http://nyc787.blogspot.com/2010/06/first-43.html) all LN's from 07 to 49 are taken now, so there is no way in hell for LOT to get one, right?
But wait! LN04, LN05 and LN06 are waiting for someone to pick it up! Pure coincidence, wrong article, or...?
