Booking Strategy
For the Oslo to Lisbon route, the sweet spot for booking is 6-10 weeks before departure, with Tuesday and Wednesday departures typically €40-80 cheaper than weekends. Norwegian usually offers the lowest base fares but charges for baggage, while TAP includes a checked bag in their standard fare. November and February offer the best value with prices dropping to €280-320 for round trips. Avoid late July and August when prices peak above €500. Use Skyscanner’s ‘whole month’ view to visualize price trends, then book directly with the airline for better customer service if issues arise. Norwegian operates this route seasonally (typically April-October), so check dates carefully if seeking direct flights outside peak season.
Route Tips
- Use Oslo Gardermoen’s express train (Flytoget) from Oslo S—it’s faster than the bus and takes 20 minutes to the airport for €20.
- Norwegian often sells discounted tickets through their app before they appear on aggregators—check there first for deals.
- Portuguese immigration is usually quick, but have your return ticket and accommodation confirmation ready as they sometimes ask for proof of funds.
- TAP Air Portugal offers Lisbon connecting flights to other Portuguese cities (Porto, Faro) at reasonable prices if you want to explore beyond Lisbon.
- If flying indirect via Amsterdam Schiphol, allow at least 1.5 hours transfer time as terminal changes may be required.
- Norwegian’s seasonal Oslo-Lisbon route typically runs from late March through October—check their schedule if specifically seeking direct low-cost options.

These shoulder and low season months see significantly reduced demand since Portuguese weather is milder and it’s outside the main tourist season.

How far in advance should I book Oslo to Lisbon flights?
Book 6-10 weeks ahead for the best balance of availability and price. Airlines typically release their cheapest fares 8-12 weeks before departure.
