I wonder how many other airports stepped up their security. Maybe some of those you mentioned did too. I was in three airports that day, but I didn't go through security at O'Hare or SeaTac. It could have been just Knoxville, but if an alert had been issued, other airports were doing it as well. I don't suppose it really matters at this point.
