My long feature on using Wi-Fi at airports—which ones, how much, and how—is online at JiWire: JiWire asked me to talk to the major airport hotspot operators and collect both a comprehensive list and write up an extensive set of information about cost, availability, and tips. There are no big surprises in the article, but I hope it will be a useful guide for anyone planning business travel.

It shouldn’t have come as a surprise, but most airports in North American now have significant if not airport-wide coverage. A few large U.S. airports still lag, such as Chicago, Atlanta, and Los Angeles, but Chicago and Atlanta will shortly have comprehensive service.
