Yes, Frontier Airlines does operate international flights, mainly to destinations across Mexico, the Caribbean, and Central America. Some popular routes include Cancún, Montego Bay, San José (Costa Rica), and Punta Cana. These flights depart from major U.S. cities such as Denver, Orlando, and Miami. Frontier’s international service follows the same à la carte pricing model as its domestic routes, so baggage and seat selection fees apply. Always check passport and entry requirements before you travel abroad.
