Another season, another blogging hiatus. This time, much of it has been spent in different time zones; stay tuned for photos. Meanwhile, for folks who are serious about their flying, a few sites may be of use. SeatGuru gives you the lowdown on your seat (such as legroom, power outlet availability, and annoyances like noisy MD-80 engines right outside your window). FlyerGuide is a wiki with information on frequent flyer programs for several airlines. ExpertFlyer may also help you get a business-class upgrade, though it is subscription-based. And of course, travel site aggregators like Kayak are good for doing quick, detailed searches for the best airfares, hotel rates, and rental cars.
