Maybe (just maybe) this "no stand up" was some kind of increased security for the first flight back into Reagan airport (the last to re-open and the closest to Pentagon).... That is (maybe) it was just for the one flight the journos happened to be on. I have flown (on AA) five times since Sep 11 and there has never been such an announcement. Not only were we allowed to stand to get to the lav, we could even wait in line for one to become available - just like before.
