I'm a first time flyer...I'm not really worried about the flight itself,noises don't bother me and I'll have a Kindle to keep me company..what scares me is the process at the airport. I have no idea what I'm doing...I'll only have a carry on bag and a purse with me...I'm flying from Michigan to Louisiana with one stop in Houston..changing planes also scare me...any advice or tips would be most welcome...
