Fares from Oslo to Lisbon (NOK)
Lisbon is a genuine year-round destination, mild even in winter, so fares from Oslo are driven as much by the Norwegian holiday calendar as by the season. Summer and the Easter and Christmas peaks are the dearest; late autumn and midwinter (outside the holidays) are the cheapest. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | — | low |
| February | — | medium (vinterferie) |
| March | — | medium |
| April | — | medium-high (Easter) |
| May | — | high |
| June | — | high |
| July | — | very high |
| August | — | high |
| September | — | medium (best value) |
| October | — | medium (høstferie) |
| November | — | low |
| December | — | high (Christmas) |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 4h 15m):
- TAP Air Portugal — the Portuguese flag carrier and the most frequent operator, with the widest choice of departure days and easy onward connections across Portugal, Brazil and West Africa from its Lisbon hub.
- SAS — non-stop from Gardermoen; the full-service Scandinavian option, with fare bundles that include bags and seat selection.
- Norwegian — non-stop on a 737, usually the keenest headline price if you travel with only a cabin bag.
On a four-hour flight there is no one-stop routing worth taking for its own sake — every sensible option here is direct. Connections through Copenhagen, Frankfurt or Amsterdam exist and can occasionally be cheaper, but they roughly double the journey time, so a non-stop is almost always the better buy.
When to book & how to save
- Book 1–3 months ahead for summer and Easter; those weeks sell out first and prices only climb closer to departure.
- Target September and October for the sweet spot: Lisbon stays warm well into autumn, the crowds thin and fares fall back to spring levels.
- Consider winter sun: Lisbon is mild and bright even in January, and outside the Christmas week midwinter fares are among the lowest of the year.
- Travel light on the basic fares: Norwegian and TAP’s cheapest tickets are cabin-bag only — add a checked bag only if you need it and compare the all-in cost.
- Set a price alert: TAP and Norwegian both run regular promotions on this route, so it pays to watch rather than book on impulse.
Arriving in Lisbon
Flights land at Lisbon–Humberto Delgado (LIS), unusually close to town at about 7 km north of the centre. The cheapest way in is the Metro (red line) from the airport station, around 20–30 minutes to the centre for roughly 20 kr including the reusable card. The Aerobus shuttle and city buses also serve the terminal, while a taxi or ride-hail to the centre costs roughly 150–250 kr and takes 15–20 minutes outside rush hour.
Frequently asked questions
How long is the flight from Oslo to Lisbon?
Non-stop flights take about 4 hours 15 minutes. The return leg to Oslo can be a little longer or shorter depending on winds. TAP, SAS and Norwegian all fly it direct, so there’s no connection time to add unless you deliberately book a cheaper one-stop routing through a European hub.
Are there direct flights from Oslo to Lisbon?
Yes. TAP Air Portugal, SAS and Norwegian fly non-stop from Oslo Gardermoen to Lisbon, with TAP operating the most frequent service. With three carriers on the route you can usually find a direct flight on the day you want, though frequencies are lower than on a big city-pair like Oslo–Barcelona.
How much does it cost to fly from Oslo to Lisbon?
A typical economy return runs about 1 500 – 3 700 kr depending on the season. The best deals dip to around 1 500 – 1 900 kr in late autumn and midwinter, while July, August, Easter and Christmas sit toward the top of the range.
What is the cheapest month to fly from Oslo to Lisbon?
November, January and September are usually the cheapest months to fly. September is a standout for weather and value, and midwinter outside the Christmas week is the cheapest of all. Avoid July, August and the Easter and Christmas peaks.
Which airlines fly from Oslo to Lisbon?
Three airlines fly the route non-stop: TAP Air Portugal, SAS and Norwegian. TAP is the most frequent and connects onward across Portugal and beyond; SAS offers full-service fares with bags and seat selection; Norwegian usually has the lowest cabin-bag-only headline price.
Which airport do I fly into in Lisbon?
All flights use Lisbon–Humberto Delgado (LIS), the city’s single main airport, just 7 km north of the centre — one of the closest big-city airports in Europe. The Metro red line runs straight from the terminal into town, so getting to your hotel is quick and cheap.
How far in advance should I book Oslo to Lisbon flights?
Aim to book 1 to 3 months ahead, and earlier for summer and Easter travel. Fares to Lisbon are lowest a month or two out and climb as the date nears, especially over the Norwegian school holidays, so early booking almost always wins for peak dates.
Is it cheaper to fly on weekdays?
Often, yes — Tuesday, Wednesday and Saturday departures tend to be a little cheaper than Friday and Sunday, when weekend-break demand is highest. Flying out and back midweek can save a few hundred kroner on a return, so being flexible by a day or two is worthwhile.
