All Points rewards systems with Hotel Groups and Airlines are free and highly encourage you to create a rewards system for each. Miles and points tend to never expire and in most cases, and can be transferred to a partner group to utilize in different ways.
In what ways will benefit you, is what you will need to weigh out for each situation. Some information may overlap as there are multiple ways to earn through each group.
**Please ensure at the time of check-in whether it be for a participating Hotel or Transportation company that they confirm and/or add the applicable rewards you wish you build upon.
