Should I fly into EZE or AEP?

International flights almost always land at EZE (Ezeiza). AEP (Aeroparque) is mostly for domestic or regional flights within South America.

Is it cheaper to buy tickets in Argentine Pesos?

No, if you are booking from outside the country, international booking engines will charge you in your home currency. Do not try to use a VPN to spoof an Argentine IP address; it rarely results in lower prices and often leads to transaction blocks.

Finding Cheap Flights to Buenos Aires

To get the best price, book your flights 3 to 5 months in advance and aim for arrival dates in May, June, or September. Always monitor flights using Google Flights to track price drops for your specific dates.

Set your departure window. Avoid traveling between December and February, which is peak summer season. Aim for the shoulder seasons—late April to early June or September to November—to see fare drops of 20-30%.
Use price tracking tools. Open Google Flights, enter your home airport and EZE (Ezeiza International). Toggle the 'Track prices' switch for your dates. Check the 'Date grid' view to see if shifting your trip by 2-3 days saves you money.
Consider secondary hubs. If flying from North America or Europe, check flights to Santiago (SCL) or São Paulo (GRU). Sometimes a budget carrier flight from a regional hub is cheaper than a direct long-haul flight to Buenos Aires.
Book at the right time. The 'sweet spot' for booking international flights to Argentina is 120-150 days out. If you see a price that is below the historical average for your route, book it immediately rather than waiting for a last-minute deal.
