Frontier Airlines has asked a bankruptcy court to give it an additional four months to file its reorganization plan, saying that crafting one now would be premature.

The Denver-based carrier currently has until Feb. 4 to file its plan without having to worry about other parties submitting competing plans. If granted, the extension would give Frontier until June 4 to file a plan exclusively.

Frontier said the first nine months of its bankruptcy “have gone smoothly” but added there’s a “great deal more that needs to be done,” according to documents it filed today with the court overseeing its bankruptcy.

The carrier filed for Chapter 11 protection last April. Since then, it has shaved tens of millions of dollars in costs by reducing its fleet, paring its work force and reworking labor contracts, among other efforts. Just today, its pilot group ratified long-term labor and benefit concessions that will help the carrier further reduce its expenses.

Frontier also has taken steps to increase revenue by charging for checked bags, introducing a new fare structure and raising various fees.

The company asked for, and received, an extension to file its plan last year. Other airlines that have fought through bankruptcy have requested numerous extensions as they reorganized.
