Sun Country Airlines launched a new version of its frequent flyer program Tuesday that allows members to collect points for how much they spend instead of how far they fly.

The Sun Country program is a re-designed version of its Ufly Rewards program and is designed, in part, to appeal to families. The program also allows members to form groups of up to 10 to pool their points to obtain a free ticket faster.

"We believe that this program, and 'pooling' in particular, provides a huge benefit to our loyal customers," said Drew Hack, director of marketing and sales.
