Let me say that I COMPLETELY agree with the 12 minute delay here. Clearly the right thing to do. However, it's not always so clear. For example, I was held up on another WN flight once by about 15 minutes because of a gate agent decision (we were told). One of the members of a college sports team was held up in the security line at OAK. It was a long line - but not unheard of. Yes, it was only 15 minutes. But I had a long drive in bad weather ahead of me and really didn't appreciate it. Was that the right thing? Not always clear.
