Prep Your Phone
Most things you want to solve in an airport—checking your flight status, finding out about a gate change, requesting an upgrade—can now be solved on your smart phone, says Paco Underhill, who consults on airport design and human behavior, travels 150 days a year and has written such books as What Women Want and Why We Buy. Before flying, make sure you have the (free) app for your airline installed so that, should a problem arise, you can get typing while everybody else gets in line.
