its been over 4 1/2 years since i've flown and i've never flown with gadgets like the ones i have now. i dont know what to expect. i plan on checking my suitcase and carrying on my backpack. the backpack will have my macbook, ipods, psp, money, and probably another random thing or two. could anybody tell me what to expect and/or give me suggestion as to what to do. i'm 15 and this will be my third cross country flight and my second alone, but my first without somebody watching out for me. i also have a one hour layover in dallas on the way there.
