I am a first time flyer? I need help?

Don't stress(: I've been flying ALONE since I was 5 & I'm 14 now. Check the flight status monintors as soon as you get off in Texas. Then go directly to the gate to make sure the plane isn't going to depart late or early. You'll usually be near a bathroom and quick reasturants (McDonalds, Starbucks etc.) And shops where you can pick up some gum or a magazine. Then just go back to the gate and relax untill boarding time.
