Your seat back, a black hole? If your flying on United and leave something behind it might be. Turns out airlines just aren’t that interested in reuniting you with your lost personal items. I read this article a while ago on Consumerist.com and thought it couldn’t hurt to remind everyone that you should always check your seat back before the plane begins to land. Especially since you’ll be flying home after Christmas and may have one or two zippy new tech toys with you.
