Upon arrival I went to a handy check-in kiosk only to discover it could not find our reservation. So we stood in line. After 20-30 minutes of non movement in the line, the long line, security personnel asked everyone on our side of the terminal to move to the other side of the building. We waited for probably 45 minutes before we were allowed to return. Two hours later we had missed our flight, while waiting in line but had lots of practice of non-anxious presence.
