Is it cheaper to book one-way or round-trip?

For international flights to Latin America, round-trip is almost always cheaper. If you are flying one-way, legacy carriers often charge a massive premium, so look into budget airlines for the outbound leg.

Should I use a travel agent for last-minute trips?

Only if you are struggling with complex multi-city itineraries. For standard last-minute flights, online search tools are significantly faster and more accurate.

Finding Last-Minute Flights to Latin America

Use Google Flights' Explore tool to view a calendar of prices and set up price alerts for specific routes. For last-minute savings, focus on major hubs like Mexico City, Panama City, or Bogotá, and be ready to book at least 72 hours before departure to avoid the highest legacy carrier premiums.

Use the 'Explore' Map. Go to Google Flights, enter your departure city, leave the destination blank, and click 'Explore'. Select Latin America on the map. This identifies the cheapest entry points into the continent rather than fixing your heart on one specific city.
Check Low-Cost Carriers Separately. Major search engines often miss regional budget airlines like Volaris, Viva Aerobus, or Sky Airline. Search these airline websites directly once you have identified a potential route.
Look for 'Hidden City' Options. Use a tool like Skiplagged to see if a flight with a layover in your destination city is cheaper than a direct flight. Only do this if you are traveling with carry-on luggage only, as your checked bags will go to the final ticketed destination.
Monitor for the 72-Hour Window. If you are within 7 days of your trip, prices fluctuate daily. Check prices at 3:00 AM local time for the airline's hub, as many automated pricing systems reset or dump unsold inventory during off-peak hours.
