Spirit would rather ride with Frontier than

JetBlue.

The carrier rejected an acquisition offer from JetBlue Airways Corp. in favor of an existing plan to merge with rival budget airline

Frontier Group Holdings Inc.

JetBlue’s offer for Spirit came with a higher price tag than Frontier’s cash-and-stock offer that was originally valued at $2.9 billion. But Spirit’s board said it believed there was too much risk that regulators would bar a merger with JetBlue. Still, JetBlue said Monday that it isn’t giving up and made the details of its latest offer public in an effort to win over Spirit shareholders. Spirit shares fell 9.4% Monday.
