Sorry, for this repeat post - I accidentally put it in the women's section, when I meant it for all:
Just completed a trip to Boston. Going through the security line at Seatac, my boyfriend and I accidentally switched tickets. The name on the ticket obviously didn't match the name on the identification presented to the security woman in line, yet got through with no problem. On our return trip from Logan we decided to experiment and see if we could get through again with a ticket that didn't match our ID's. We even went in separate lines to ensure the screener didn't just assume we were together. We both got through again! But, not to worry because even though they let me through with someone else's ticket, they did confiscate the very dangerous, lethal weapon I was carrying in my make-up bag: my eye liner sharpener!
