Riga to Lisbon is a genuine non-stop route: airBaltic flies it directly in about 4 hours 40 minutes, linking the Baltic to the Atlantic without a change of plane. It’s a seasonal service that runs more often in the warmer months, so timing matters if you want the convenience of a direct flight. This guide covers who flies the route, what a fair return fare looks like in euros, and when to book for the best price.
Route: Riga (RIX) → Lisbon Humberto Delgado (LIS)
Distance: approximately 3,450 km (2,140 miles)
Non-stop flight time: about 4h 40m westbound
Direct flights: Yes — airBaltic flies non-stop from Riga to Lisbon. It’s a seasonal route, typically around three flights a week in the winter, rising to roughly six a week over the summer peak. One-stop options exist but rarely beat the direct on total time.
Fares from Riga to Lisbon (EUR)
Lisbon is a year-round city break, but fares and frequency both climb in summer, when the direct service runs most often and demand is highest. Spring and autumn are the sweet spot for mild weather and lower prices; winter is cheapest of all, though with fewer weekly departures. The figures below are typical economy return fares in euros — the lowest sit in the shoulder and off-season, the highest around the July–August peak.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | €110 – €180 | low |
| February | €110 – €180 | low |
| March | €120 – €200 | medium |
| April | €130 – €220 | medium |
| May | €140 – €230 | medium-high |
| June | €160 – €250 | high |
| July | €180 – €280 | very high |
| August | €180 – €280 | very high |
| September | €150 – €240 | high |
| October | €130 – €210 | medium |
| November | €110 – €180 | low |
| December | €130 – €220 | medium (holidays) |
Reference points from our own deal tracking: a strong hand-baggage return lands around €85–€120, and a good fare with a checked bag included sits near €135–€170. A typical fair price is roughly €155, and anything under about €120 is worth booking quickly. These are indicative economy returns, not fixed quotes.
Airlines on this route
Non-stop (about 4h 40m):
- airBaltic — the only carrier flying Riga to Lisbon non-stop, on its Airbus A220 fleet; seasonal frequency, heaviest over the summer.
One-stop (an alternative on off-peak dates or when the direct is full):
- Lufthansa via Frankfurt or Munich — frequent connections and full-service comfort into Lisbon.
- TAP Air Portugal via a European hub — Portugal’s flag carrier, with a strong onward network from Lisbon if you’re travelling beyond.
- LOT Polish Airlines via Warsaw and Finnair via Helsinki — useful one-stop options that sometimes undercut the direct in the off-season.
For most travellers the airBaltic direct is the obvious pick on the days it runs — it’s the fastest by a wide margin. If your dates fall on a day without a direct flight, a single stop through Frankfurt or another European hub keeps the trip under about seven hours.
When to book & how to save
- Book 1–3 months ahead for the best fares; the direct service sells well in summer, so the cheapest seats go early.
- Travel in the shoulder seasons (April–May, September–October) for mild weather, lower prices and still-frequent flights.
- Check the day of the week: because the route is seasonal, direct flights don’t run daily — being flexible by a day or two can be the difference between a non-stop and a connection.
- Compare fare types: airBaltic’s cheapest fares are hand-baggage only, so if you need a checked bag, price the bundle rather than adding it later.
- Watch winter frequency: the direct thins out in the colder months, so book ahead if you want the non-stop over Christmas or New Year.
Arriving in Lisbon
Flights land at Lisbon Humberto Delgado Airport (LIS), only about 7 km north of the city centre — one of Europe’s most central airports. The Metro (red line) runs straight from the terminal into town for around €2, and the Aerobus and city buses are similarly cheap. A taxi or ride-hail to the centre takes 15–25 minutes and costs roughly €12–€20 depending on traffic and time of day.
Frequently asked questions
Are there direct flights from Riga to Lisbon?
Yes. airBaltic flies non-stop from Riga to Lisbon in about 4 hours 40 minutes. It’s a seasonal route — typically around three flights a week in winter, rising to roughly six a week over the summer — so it doesn’t operate every day. On days without a direct, a one-stop connection through a European hub is the alternative.
How long is the flight from Riga to Lisbon?
The non-stop airBaltic flight takes about 4 hours 40 minutes westbound, and a little longer on the way back against the prevailing winds. One-stop itineraries through Frankfurt, Warsaw or Helsinki usually total around 6 to 8 hours depending on the connection.
How much does it cost to fly from Riga to Lisbon?
A typical economy return runs about €110–€280 depending on the season. The best hand-baggage deals dip to around €85–€120 in the quieter months, while the July–August summer peak sits toward the top of the range. A fare with a checked bag included typically starts near €135.
What is the cheapest month to fly from Riga to Lisbon?
January, February and November are usually the cheapest, with returns from around €110. Prices climb through spring and peak in July and August, so if you want warm weather at a lower price, aim for May, September or October.
Which airlines fly from Riga to Lisbon?
Non-stop: airBaltic, the only carrier flying the route directly. One-stop alternatives include Lufthansa (via Frankfurt or Munich), TAP Air Portugal, LOT Polish Airlines (via Warsaw) and Finnair (via Helsinki), which are handy on dates when the direct doesn’t run.
Which airport do I fly into in Lisbon?
You arrive at Lisbon Humberto Delgado Airport (LIS), the city’s main and only commercial airport, just about 7 km north of the centre. The Metro red line connects the terminal directly to the city for around €2, making it one of the easiest airport transfers in Europe.
How far in advance should I book Riga to Lisbon flights?
Aim to book 1 to 3 months ahead. Because the direct service is seasonal and popular in summer, the cheapest non-stop seats go early — especially for July and August travel and around the Christmas holidays.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) tend to be cheaper than Friday to Sunday. On a seasonal route, checking a couple of alternative days also improves your chance of catching a direct flight rather than a connection.
