Boingo and Skype Zones could be a good thing. The instructions and the links suggest it's very much in early beta. If you try it with success be sure and let us know.

Skype Zones, which enables Skype usage across the Boingo network of 18,000 global hotspots. The service is being initially offered at $8 a month for unlimited Wi-Fi access for Skype calls, which is significantly less than the $22 a month that Boingo currently charges for unlimited data access. Skype Goes Boingo For Wi-Fi

I have a Boingo access at my local UPS store. I went to sign-up via the Skype Store and it takes you to a Boingo account. That then asks you for all your details. It's confusing when it asks you for a name and password. Many will try their Skype name and offer up their Skype password. It isn't yet integrated with Skype and the option is not available via your Skype Account. So at the credit point I stopped. I'm happy to open an account for when I next need it. Just let me tick a box in my Skype account and let me charge it there. Still next time I'm in an airport or another location and want to connect I'll remember Boingo and try it out.
