Spirit Airlines rejected Frontier Airlines’s second merger bid, opting to continue on its current path to emerge from bankruptcy. The low-cost airline filed for bankruptcy last year after the Justice Department blocked a proposed merger with JetBlue.

Discount carrier says a merger would be a better path out of bankruptcy for Spirit, which has rebuffed the latest proposal.

Frontier said in a release that it has met with Spirit’s board and executives since it made its proposal this month.
