AMEX has enabled registration for the American Express Boingo Preferred Plan. With it, American Express Platinum card members are able to use Boingo in all Global WiFi hotspots. This is a $59 retail value. There are many Boingo hotspots out there and the company also publishes a handy WiFi Hotspot finder (incl. free hotspots).
Eligible American Express Card Members can enjoy complimentary unlimited Wi-Fi access at over 1 million hotspots worldwide on up to four Wi-Fi devices without incurring any roaming fees!
I think this is an awesome addition to my AMEX Platinum!
