December in Buenos Aires and nearby regions is festival season—expect Christmas markets, outdoor tango shows, cultural events in Palermo and San Telmo, and New Year's Eve celebrations along Puerto Madero with fireworks. Mar del Plata begins to attract beachgoers late December, increasing travel to Ezeiza and coastal routes. In Los Angeles, December features holiday parades, concerts, and seasonal attractions (e.g., Disneyland holiday events near Anaheim) which can increase departures from LAX earlier in the month. These events drive higher demand on flights between Los Angeles International Airport (LAX) and Ministro Pistarini International Airport (EZE), so book early and consider event dates when planning.
