How to Get Cheap Flights to Costa Rica (2026)
Quick answer
To fly to Costa Rica for less, compare the whole market rather than one airline, and travel in the green season (roughly May to November) when fares and crowds are lower. San José (SJO) is usually the cheapest gateway, but Liberia (LIR) can save a long transfer to the Guanacaste beaches. Stay flexible on dates, book one to three months out for North American routes, and set a price alert.

1. Know the two seasons that drive prices
Costa Rica has a dry season and a green (rainy) season, and they pull fares in opposite directions. The dry months are the busiest and priciest; the green months are quieter, greener and cheaper, with afternoon showers rather than all-day rain in many regions.
| Season | Months | Fare level |
|---|---|---|
| Dry (peak) | December – April | Higher; holidays highest |
| Green shoulder | May, June, November | Lower |
| Green low | September – October | Lowest, fewest crowds |
2. Choose the right airport
Costa Rica has two main international airports, and the cheaper one depends on where you are headed as much as on the fare.
- San José (SJO) — the primary hub with the most flights and usually the lowest fares; central for the Central Valley, Arenal, Manuel Antonio and the Caribbean side.
- Liberia (LIR) — smaller, in the northwest; closest to the Guanacaste beach resorts, so it can cut a long ground transfer even if the fare is similar.
3. Be flexible with your dates
The same route can move a lot depending on the day. Midweek departures are typically cheaper than weekends, and shifting a trip by a few days can drop the fare noticeably. Use a cheapest-day view to spot the lows across a whole month, then plan around them.
4. Book in the right window
For North American departures, roughly one to three months ahead is a reasonable target. For long-haul from Europe, aim two to six months out. The dry season and holiday weeks reward booking earlier, since the lowest fares disappear first.
5. Compare direct against one stop
Non-stop flights exist from several North American cities, but a single connection through a major hub is frequently cheaper. If the layover is on one ticket and comfortably timed, the saving can be worth the extra hour or two.
6. Watch out for self-transfers
Some of the cheapest itineraries are two separate tickets stitched together. If you miss the second flight because the first was late, no airline is obliged to rebook you. Only take these when the connection is long and you understand the risk.
7. Price the true cost, not just the fare
Low-cost and basic-economy fares add for bags, seats and sometimes check-in. A cheap headline number can climb once you include a checked bag and your onward domestic transfer inside Costa Rica. Compare the all-in total for the way you actually travel.
8. Set a price alert and be ready to book
Fares change daily with demand and seat availability, not with how often you search. Let an alert watch your route and buy on the dip. Cheap seats are limited, so have passenger details ready to complete checkout fast when a good fare shows up.
9. Track your flight on the day
Once booked, a live flight tracker tells you if your aircraft is delayed inbound — handy when a connection through a US hub feeds your Costa Rica leg. Track any flight live on ScanFlyGo →
