Getting Nervous

I am getting nervous about my trip to Iowa with everything going on with flying right now. I leave on August 29 and this will be the first time I have flown alone. Some time to attempt a solo voyage in the midst of a high terror alert. On the plus side- since I will have to check my bag (want to keep my shampoo!) I won't have to carry anything as I run through the airport to make my connection. Trying to see the positive.
