Spirit Airlines rejected Frontier Airlines' second attempt of trying to merge and is moving forward with its bankruptcy plans.

Frontier had pitched the bankrupt airline on a coupledom that it claimed would have created a formidable low-cost competitor in the battle for passengers against American Airlines, Delta, Southwest, and United. While Spirit said a merger could create a “potent competitor in the marketplace” they’re just not that into it.

(Reuters) - Spirit Airlines on Wednesday said it expects to exit bankruptcy in the first quarter and rejected a merger with rival Frontier Group, saying it was not favorable for the low-cost carrier.
