Allegiant Air: Often offers seasonal, low-cost nonstop service from Atlantic City International Airport (ACY) to Florida destinations, making it a top budget choice for February travelers who can travel light and book ancillaries. Spirit Airlines: Ultra-low-cost with competitive fares to Fort Lauderdale (All Airports), but expect optional fees for bags and seat selection. JetBlue: Provides a comfortable coach experience with more legroom and free Wi-Fi on many flights, often routing via larger Northeast hubs if not nonstop. American and Delta: Legacy carriers that frequently offer one-stop connections from ACY via Philadelphia or Atlanta, good for loyalty benefits and more flexible schedules. Choose based on priority: price (Allegiant, Spirit), comfort and connectivity (JetBlue, American, Delta). Always compare total cost including baggage and change fees before booking.
