I was flying back from Tennessee Thursday and I arrived at the airport in Nashville at 9:30 am.  I was scheduled for the 1:30 pm flight and I wanted to check in early.  Next to the NW desk, I see about 15 middle easterners at the Delta desk.  They have a giant cart filled with crap and they are boisterous.  I go to the counter and the girl asks me if I want to take the 10:10 am flight.  I say yes but think this is how ironic stories start.  I tell her if there is no room that it is ok and I will wait.  She gets me on the flight and I think at least I will not have to travel with the menagerie next to me.   I get on the plane in an exit row next to the window.  I am getting comfortable when I hear a ruckus.  I look over and I see the middle easterners board the plane.  They all have giant carry-on bags and are trying to find overhead bins.  I am feeling nervous but things settle down and they shut the cabin door for take-off.  The next thing I know they open the door and let three more on.  Each carrying their giant carry-on bag and looking for overhead space.  What a cluster f-ck!  As this is going on the others are going back into their bags and getting stuff out and moving around the cabin.  At this point, I am thinking about leaving the plane.  I am wondering why the hell you need to show up three hours early.  While this is going on I am trying to figure out who the leader is and who can help on the flight in case things go to shit.  We take-off and land and all went well.  Nevertheless, if this is the new and improved security, we are screwed!
