It's available at m.flyertalk.com, however, it was never intended to be used in production. This was a skin we made as a proof of concept that was unintentionally released to the public. We've received multiple requests to make changes or fixes to the skin, but it's never been something that we've had the time to prioritize.

We are working on an official mobile skin that we will support, but it wil be totally different from the existing one.
