I signed on to Boingo while on a layover in Chicago O'Hare airport, for what I thought was a one-time $6.95 fee for 24-hours use. After a few minutes online, I lost the signal, so signed on again. Two days later, Boingo hit my credit card for another $6.95, and when I called to complain, they told the 24 hours had to be "contiguous, " in other words, signing off for any reason starts the clock ticking again with a new $6.95 fee. I've taken all of their software off my laptop, and after reading some of the other reviews, will monitor that credit card carefully. A dishonest, misleading way to do business!
