Fares from Paris to Seoul (EUR)
Seoul is a year-round destination, but fares swing with the seasons and Korean holidays. Spring cherry-blossom (late March–April) and autumn foliage (October) are popular and pricier; the summer school holidays and the Christmas/New Year peak are the most expensive; late winter and early summer are the cheapest. The figures below are typical economy return fares in euros — the lowest are usually one-stop itineraries, with nonstops sitting toward the higher end.
| Month | Demand | What to expect |
|---|---|---|
| January | — | medium |
| February | — | low-medium |
| March | — | medium-high (blossom) |
| April | — | high (blossom) |

Checked against every return fare on sale as we write, a typical fair price is roughly €550 — the connecting median is €591, so that is close. The floor is €526 on an Air China connection, so a return under about €570 is a genuinely good one and there is nothing in the three or four hundreds to wait for. The non-stops split in two: T’way Air from €606, barely above the cheapest connection and excellent value for a direct, and Air France at €1,152–€1,178, nearly double.
Airlines on this route
Non-stop (about 11½ hours):
- Air France — nonstop Charles de Gaulle → Incheon, daily; full-service with a checked bag on standard fares.
- Korean Air — nonstop from Charles de Gaulle; South Korea’s flag carrier, strong hard product on the A380/787.
- Asiana Airlines — nonstop from Charles de Gaulle; well-rated Star Alliance carrier (now merging into Korean Air).
- T’way Air — low-cost long-haul nonstop from Charles de Gaulle; the budget option, so check the bag and seat allowance.
One-stop (usually the cheapest, about 14–19 hours total):
- Qatar Airways via Doha and Emirates via Dubai — frequent, comfortable, and often the best-value premium economy.
- Turkish Airlines via Istanbul — wide schedule and typically among the lowest headline fares.
- Chinese and other Asian carriers via their hubs — frequently the cheapest connecting fares to Seoul.
Because the one-stop carriers compete hard, they usually undercut the nonstops by €80–€200. If time matters more than money, book a nonstop; if price is the priority, a single stop through the Gulf or Istanbul is the sweet spot.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and choice; long-haul fares to Seoul rarely fall in the last few weeks.
- Avoid the peaks — the summer school holidays, the cherry-blossom and autumn-foliage weeks, and Christmas/New Year are the most expensive.
- Fly in the shoulder months (late winter, early summer, November) for the lowest fares and thinner crowds.
- Consider a one-stop through Doha, Dubai or Istanbul if budget is the priority — the connecting carriers usually beat the nonstops.
- Check checked-bag rules: the full-service carriers include 23–30 kg to Seoul, but the cheapest low-cost and “light” fares may not — compare the all-in price.
