I am aware of the following related question: Overview of wireless in airports. If it is free it would be nice, but I am willing to pay for my Internet access at airports/hotels. The only problem is that it is often a hassle to get access at these access points. I don't like adding cc details to website when I am at a terminal building of an airport. Since I am a big fan of FON, where you share Internet access with fellow members worldwide, I am wondering if there is such "roaming" service for Wi-Fi access. At many airports you see that they offer access to partners.
So, my question is, if there is a company which offers worldwide Wi-Fi roaming services for a fixed fee?
