To sign up you will have to take a WAG of how much the service is worth it.
One Month or month to month = $6
A full Year = $34.99
And 5 Years = $140
N/R travel on many airlines and frequently will be a good deal.
Travel on your own affinity airline maybe not so good - use your own airline N/R tools .
You can use this service FREE for one day - ONLY once and must cancel your obligation
to continue within 24 hours or be charged the minimum I believe $6 ?
