Be very, very careful with Boingo Wireless hotspots.
On a recent trip from Madrid to Ottawa, I had a 6-hour layover in Newark Liberty Airport (EWR). I decided to go ahead and pay $7.95 USD for a 24-hour access pass on Boingo Wireless so I could catch up on news and mail, while passing the time. I didn't want to subscribe to anything (I'm not a frequent-flier, I just happened to want access that day), so I bought a day pass:
Here's what it says:
"Don't travel much? Get a Boingo AsYouGo account for just $7.95 per Connect Day for locations within the U.S. & Canada and $9.95 internationally. A Connect Day includes unlimited access in any location for 24 hours. No monthly fees apply."
I used the pass I bought on March 24th, 2 hours 35 minutes in Newark (EWR) and then 5 minutes in Ottawa (YOW) while waiting for checked luggage to arrive (email addict!). Note that the plan description says "in any location", not "in any single location". Imagine my surprise when I found two charges on my credit card bill: one on March 24th (expected), and another one two days later on March 26th! I called customer service, and they refused to reverse the second charge, informing me that it was incurred when I logged in for a second time in another airport.
I've reviewed the user agreement at [https://signup.boingo.com/signup/DisplayBCA.app], especially Section 3, "Locations and usage", and at time of this writing, it doesn't appear to me to contain any language restricting usage of a day pass to a single location, or any warning that logging in from a second location during the same 24 hour period will result in a new charge. I've since written to their customer service to explain the situation and request a refund of that second charge. I'll update this post when I hear back from them.
UPDATE: Sounds like it was simply a software glitch! I've been refunded.
