"Spirit Airlines Soars as Fourth-Quarter Forecast Exceeds Expectations"

Spirit Airlines stock surged 17% after raising its fourth-quarter forecast, expecting revenue of about $1.3 billion and improved negative margins of 12% to 13%, citing strong bookings, lower fuel costs, and progress in discussions with Pratt & Whitney regarding compensation for an engine issue. This comes after a recent decline in shares following a judge's ruling blocking JetBlue Airways from acquiring the budget carrier.
