Frontier Airlines offers discounts and expands routes after Spirit Airlines ceases operations.

Frontier Airlines announced systemwide fare discounts and a $199 unlimited summer pass to support travelers affected by Spirit Airlines ending operations. Frontier now serves over 100 routes previously flown by Spirit and will add nine more routes plus 15 daily flights this summer. The airline offers up to 50% off base fares for travel through November 19, with special discounts on certain days and blackout dates. This move helps maintain access to affordable travel options for former Spirit customers and expands Frontier's network significantly.
