Spirit Airlines is rebuffing the latest takeover offer from Frontier Group, with the discount airline saying that it prefers focusing on its current reorganization plan.

Spirit Airlines Tuesday rejected Frontier's most recent merger proposal, opting to proceed with its own standalone recapitalization without a merger instead. Spirit is currently in bankruptcy.

Spirit Airlines has again rejected a third takeover bid from budget rival and Denver-based Frontier Airlines, saying that it would focus on its own plan to emerge from bankruptcy and stabilize its finances.
