Side note, I tried to use my Amex Platinum Boingo account recently and it didn't work anymore. I sent support a message and got this back:
Thank you for contacting Boingo regarding your recent connection trouble with inflight Wi-Fi. We apologize for any inconvenience that this may have caused. Inflight Wi-Fi is not a benefit included with the complimentary service provided through American Express. Due to a recently discovered bug you may have received access on certain flights. Moving forward your American Express plan will include all the land based hotspots you’ve been enjoying but inflight Wi-Fi will no longer work.
If there's anything more we can do to help, please don't hesitate to let us know.
