Thank you for your reply! I will think about these ideas.

My main concern is how to create value in a token system.

How do investors get value for their investment and how to tokens maintain a value?

How to keep the value at a level that is acceptable to the customers of the token (Airlines) so they will use it.

I've thought of burning each token when it is used.
Allowing partial token usage, so they can use a percentage of the token for each transaction.
A few other ideas...

I'm very interested in this topic and would like to know what other think about it.

TIA
