Spirit Airlines shareholders approve $3.8B sale to JetBlue

Spirit Airlines shareholders voted Wednesday to accept a $3.8 billion buyout from JetBlue Airways, but the deal could still face a challenge from federal antitrust regulators. JetBlue emerged as the winner in a bidding war with Frontier to acquire Spirit, the nation’s biggest budget airline. Spirit announced the outcome after a brief meeting, which was held online. Spirit said only that the JetBlue deal was supported by a majority of shares voted; it promised an exact count within four business days.
