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 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.
