New way to get extra miles
From the Frontier Airlines website:
Colorado Club
Live Here?
Make visits from friends and relatives even more rewarding. Refer them to Frontier's Colorado Club and you'll both earn EarlyReturnsŪ bonus miles.
Earn 1,000 bonus miles when someone you refer joins the Club and flies to Colorado.* The more visiting friends and relatives, the more miles you earn!
Fly Here?
As if visiting Colorado weren't rewarding enough, we'll double the miles you earn to get here.* If you were referred to the Club by a friend or relative, we'll throw in bonus miles for that person, too!
Earn double miles when you join the Club and fly to Colorado. It's a win-win situation.
