JetBlue Airways Corp. and Frontier Airlines jostled for last-minute support among Spirit Airlines Inc. shareholders ahead of their vote this week in what has become a hotly contested airline-merger fight.
Spirit on Tuesday held firm to its plan to be acquired by Frontier Group Holdings Inc., saying JetBlue’s sweetened offer still comes up short and doesn’t address Spirit’s core concern that regulators won’t bless a merger with JetBlue. Spirit’s investors are set to vote on the Frontier deal Thursday.
