The operating model of $FLY: Blackbird views it as a Utility Token, which in the Web2 world would be equivalent to Loyalty Points. 

When Diners make cash purchases, they are rewarded with $FLY. $FLY can be used for payments at any restaurant under the Blackbird network. 

Under the Tokenomics mechanism, the more $FLY consumed by Diners and Restaurants, the more $F2 tokens they will receive. 

However, the whitepaper doesn't elaborate much on owning $F2 tokens. Following the design principles of other protocols, $F2 tokens are likely to be closely related to future Governance applications
