Frontier Group Holdings Inc. said it is done bidding against rival JetBlue Airways Corp. for Spirit Airlines and wants Spirit to delay its shareholder vote once again to allow Frontier more time to persuade skeptical Spirit investors.
In a letter Sunday, Frontier Chief Executive Barry Biffle said that Frontier’s latest offer for Spirit late last month was its “last, best and final” proposal, and asked Spirit’s board to publicly reaffirm its commitment to that deal. The letter was released publicly Monday.
