Avoiding Hackers on Airport Wi-Fi

Q. I'm a little wary of airport wi-fi, especially when I have to enter my credit card info and purchase it on the spot. How can I be sure these airport networks are actually secure?

A. You have every right to be concerned. Most people seem to pay very little attention to what network they're joining. Just so long as they can check their mail or bid on that amazing E.T. oven mitt on Ebay (or whatever)- and preferably for free, please. It's that kind of hurried carelessness that makes travelers such easy targets for hacking. So how can you keep your personal information safe and still dilly-dally online before your flight?
