Cheap Flights to Chile: Santiago, Patagonia and the Atacama (2026)
Quick answer
Most travellers fly into Santiago (SCL), which is the best-connected airport in Chile and usually the cheapest entry point. To save money, avoid the southern summer peak from December to February where possible, compare itineraries with one stop, and book domestic flights to Patagonia or the Atacama early. Treat the long-haul and the internal legs as one budget.

Understanding the geography first
Chile is a very long, narrow country, stretching from the dry north to the glaciers and fjords of the far south. That shape matters for flights. Almost every international passenger lands in Santiago, and the main sights are then reached by a second, domestic flight. Planning the whole route in one go helps you avoid paying twice for the same distance.
Because the country covers so many climates, the right time to go depends on where you are headed. Remember that seasons are reversed compared with the northern hemisphere, so summer is roughly December to February.
The main airports you may use
| Airport | Region | Typical use |
|---|---|---|
| Santiago (SCL) | Central Chile | Main international gateway and domestic hub |
| Calama (CJC) | Atacama Desert | Closest big airport to San Pedro de Atacama |
| Punta Arenas (PUQ) | Southern Patagonia | Gateway to Torres del Paine and the far south |
| Puerto Montt (PMC) | Lake District | Access to lakes, volcanoes and Chiloé |
| Easter Island (IPC) | Pacific | Remote island reached from Santiago |
For a first trip, many travellers combine Santiago with either the Atacama in the north or Patagonia in the south. Trying to do both in a short holiday adds a lot of flying, so decide which landscape matters most to you.
When to book and when to travel
The southern summer is the high season for Patagonia and for travellers from the northern hemisphere escaping winter. Demand and fares rise around Christmas, New Year and January. Shoulder months such as October, November, March and April often give a better balance of price, weather and crowds, although conditions in the far south can be changeable.
- Dec to Feb: long days, best hiking weather in Patagonia, highest demand.
- Mar to Apr: autumn colours in the south, fewer visitors, generally easier fares.
- May to Aug: low season in the south, good for the Atacama and for Santiago, with ski resorts in the Andes.
- Sep to Nov: spring, wildflowers and improving weather.
For long-haul fares, start watching prices several months ahead and set an alert. For the peak summer weeks, earlier is safer.
Ways to lower the cost of getting there
Compare multiple routings
Many routes from Europe and North America involve a stop, so look at different connecting cities rather than only the most obvious one. A slightly longer journey can sometimes be noticeably cheaper.
Check nearby gateway cities
Departing from a larger hub airport in your region can unlock more competitive fares than a small local airport, even after the cost of getting there. Weigh the saving against the transfer.
Keep it on one ticket
When a long flight has a connection, a single booking protects you if the first leg runs late. Separate tickets can look cheaper but leave you responsible for a missed onward flight.
Book domestic legs early
Flights to Punta Arenas, Calama and Puerto Montt can fill in the busy season, and prices rise as seats go. Once your dates are fixed, lock in the internal flights soon after the long-haul.
Baggage and practical details
Domestic flights inside Chile often have tighter baggage rules than long-haul tickets, especially on low-cost fares. If you carry hiking gear, check the weight limit for each leg before you pay. Keep important items such as medication and a change of clothes in your cabin bag in case a long itinerary delays your luggage. Entry requirements vary by nationality, so verify your passport validity and any visa or arrival rules well before departure.
Common mistakes
- Underestimating how far apart the regions are and trying to cover too much in a short trip.
- Ignoring the time needed to connect in Santiago between international and domestic flights.
- Booking Patagonia at the last minute during peak weeks.
- Forgetting that a cheap fare may exclude bags, which matters for gear-heavy trips.
Frequently asked questions
Which airport should I fly into for Chile?
Santiago (SCL) is the main international gateway and usually the best choice. From there you can take domestic flights to the Atacama, Patagonia, the Lake District or Easter Island.
When is the cheapest time to fly to Chile?
Fares are generally lower outside the southern summer, so the shoulder months and the southern winter are often better value. December to February tends to be the most expensive.
Do I need a separate flight to reach Patagonia?
Usually yes. Most travellers fly from Santiago to Punta Arenas, then continue by road. Book it early in the peak season.
Is a connecting flight to Chile cheaper than a direct one?
Often a one-stop itinerary is cheaper, but direct availability depends on your departure city. Compare both and weigh time against price.

Chile is a trip to plan as a whole. Pick your region, choose the season that suits it, compare routings into Santiago, and book the internal flights early so the total stays reasonable. Start a live search on ScanFlyGo, browse the popular routes, and use the live flight tracker once you are booked.
