Alliance & partners
Frontier Airlines is not a member of any alliance. Miles earned fly only within Frontier Airlines's own loyalty program. There are no codeshare or interline agreements with other carriers.
Worth knowing: Frontier is an ultra-low-cost carrier (ULCC) that deliberately targets leisure markets — its network is built around connecting smaller US cities directly to resort and vacation destinations rather than building a traditional hub-and-spoke connect bank.
