I was traveling last week and saw that Boingo has a couple of apps to provide wifi on their network. One gives access for a monthly charge and one that provides for an hour of time. The hourly app even has an hour of free time that you can use before you have to pay. Boingo is in a lot of spots if you are traveling. It is worth it to download the apps simply to have available if you get stuck in an airport and need access.
