This guide covers London to San José, Costa Rica (airport code SJO, Juan Santamaría) — not San Jose, California. It is a long-haul Central American route with a seasonal non-stop: British Airways flies direct in the winter season, while the rest of the year you connect once through Europe or the United States. Here is the honest picture of who flies it, what a fair return costs in pounds, and how to book well.
Route: London (LHR) → San José, Costa Rica, Juan Santamaría (SJO)
Distance: approximately 8,760 km (5,440 miles)
Non-stop flight time: about 11h 15m when the seasonal direct operates; one-stop journeys run 14–18 hours
Direct flights: Seasonal — British Airways flies non-stop from Heathrow in the winter season (from late October through March, five times weekly). Outside that window there is no non-stop and you connect once.
Fares from London to San Jose, Costa Rica (GBP)
Costa Rica’s dry season (mid-December to April) is the peak for visitors and the priciest for fares, with the Christmas and Easter holidays the busiest of all. The green season (May to November) is quieter and cheaper. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Demand |
|---|---|
| January | very high (dry season) |
| February | high |
| March | high |
| April | medium-high (Easter) |
| May | medium |
| June | low-medium |
| July | medium (summer holidays) |
| August | medium |
| September | low |
| October | low-medium |
| November | medium |
| December | very high (holidays) |
Reference points from our own deal tracking (London–San José): a genuinely good return lands around £450–£560, a typical fair price is roughly £640–£650, and everyday fares sit in the £700–£850 band. Anything under about £560 is worth booking quickly.
Airlines on this route
Non-stop (seasonal winter service, about 11h 15m):
- British Airways — non-stop from Heathrow in the winter season (roughly late October to March), operating several times a week. This is the only direct option and it does not run in summer.
One-stop (year-round, usually the cheapest, about 14–18 hours total):
- Iberia via Madrid — a single European hub and a direct onward flight to San José; frequently good value.
- Air France via Paris and KLM via Amsterdam — reliable European routings that avoid a US transit.
- American Airlines via Miami and United via Houston or Newark — often the lowest fares, but a US connection needs an ESTA.
The European connections (Iberia, Air France, KLM) avoid the US transit-visa requirement, which is worth factoring in. When the seasonal non-stop is running, it usually beats the one-stops on both time and hassle, if not always on price.
When to book & how to save
- Book 3–5 months ahead for the dry season and the seasonal non-stop, which sell out early over Christmas and Easter.
- Travel in the green season (May–November) for the lowest fares — rain tends to come as short afternoon downpours, and the rainforest is at its lushest.
- Prefer a European connection (Iberia, Air France, KLM) to skip the US ESTA/visa that comes with an American or United routing.
- Compare all-in prices including bags: full-service fares to Costa Rica usually include a checked bag, but the cheapest “light” tickets may not.
- Watch for the winter non-stop — when British Airways’ direct season opens, it can be the best-value and quickest way there.
Arriving in San Jose, Costa Rica
You land at Juan Santamaría International (SJO), about 20 km northwest of the capital, near the city of Alajuela. There is no train, so the usual options are an official orange airport taxi (roughly £20–£30 to central San José, agree the zone fare first), a pre-booked shuttle, or a car hire if you are heading straight to the coast or the volcanoes. The drive into the city takes about 30–40 minutes outside rush hour. Costa Rica uses the colón, though US dollars are widely accepted.
Frequently asked questions
Are there direct flights from London to San Jose, Costa Rica?
Only seasonally. British Airways flies non-stop from London Heathrow to San José (SJO) in the winter season, roughly late October through March, several times a week. Outside that window there is no non-stop and every itinerary connects once, most simply via Madrid, Paris, Amsterdam or a US hub.
Is this San Jose in Costa Rica or California?
This guide is for San José, Costa Rica (airport code SJO, Juan Santamaría International), the Central American capital — a popular gateway for rainforest, volcano and Pacific-coast trips. San Jose, California uses the code SJC and is a different route via the US West Coast.
How long is the flight from London to San Jose, Costa Rica?
The seasonal non-stop takes about 11 hours 15 minutes. One-stop itineraries via Europe or the United States typically take 14 to 18 hours in total, depending on the connection and layover length.
How much does it cost to fly from London to San Jose, Costa Rica?
A typical economy return runs about £640–£850. Good deals dip to around £450–£560, usually in the green season (May–November) or during a sale, while the December and dry-season peaks push toward £900.
What is the cheapest month to fly from London to San Jose, Costa Rica?
September and June are usually the cheapest months to fly. Avoid December to April (the dry-season peak) and the Christmas and Easter holidays, which are the busiest and most expensive.
Which airlines fly from London to San Jose, Costa Rica?

Do I need a US visa to connect through the United States?
Yes — if your ticket routes through a US airport such as Miami, Houston or Newark, you need an ESTA or US visa even for a same-airport connection. To avoid this, choose the seasonal non-stop or a European routing via Madrid, Paris or Amsterdam.
How far in advance should I book?
Aim for 3 to 5 months ahead, especially for the dry season and the winter non-stop, which fill up early over Christmas and Easter. Fares climb closer to departure, so booking early almost always saves money on this route.
