Well, that is the strange thing...we only fly once a year to Disney (no where else), and never had a problem...then this problem with SW. Someone mentioned it could be because we took a passenger off of our itinerary 3 weeks before we left, and that sent up a red flag. Coming home, while checking in with SW, we were told we were on the TSA "no fly list". However, she said we were fine to fly that particular day, and they did not do any extra security check on us while at the airport...huh?! She told me to call the TSA the next day. The problem is, you have to send the TSA 4 forms of ID and notarize the original birth certificates...etc... Since I am not sure we really are red flagged by the TSA, I am not sure I am going to go through all of that for myself and my children who do not even HAVE the required four forms of ID the TSA wants!
