What is SAS's carry-on allowance on flights to Svalbard?

SAS allows 7 kg in the cabin on flights from Oslo (OSL) to Svalbard (LYR). The size limit is 55 × 40 × 23 cm. SAS does not always enforce the 7 kg limit strictly on domestic Norway routes, but you cannot count on this. Pack to 7 kg and wear your heaviest gear on the plane to stay compliant.

Do I need a guide outside Longyearbyen in Svalbard?

Yes. Outside the town boundary of Longyearbyen, a guide is required for safety due to polar bear risk. Guides are legally required to carry firearms. Organised tours handle this automatically. Do not attempt to hike or travel independently beyond town limits without a licensed guide.

What is the midnight sun and Northern Lights season in Svalbard?

The midnight sun runs approximately from late April to late August — the sun does not set at all. The Northern Lights are visible from October to February when the sky is dark enough. Polar night (continuous darkness) occurs from approximately late October to mid-February, which is the peak season for lights viewing.

Why is a soft duffel recommended over a wheeled carry-on for Svalbard?

Longyearbyen's streets are a mix of snow, ice, gravel, and uneven surfaces. Wheeled carry-on luggage is extremely difficult to pull in these conditions. A soft duffel or backpack is much easier to carry. Most accommodation in Longyearbyen also requires carrying luggage up stairs or across uneven ground.

Does Svalbard have VAT and is it expensive?

Svalbard has no VAT, which makes some goods cheaper than mainland Norway. Alcohol is also available but under quota restrictions — each visitor can buy a limited monthly allocation. Despite the VAT exemption, Svalbard is still expensive for food, accommodation, and tours. Budget significantly more than a mainland Norway trip.

Carry-On Only for Svalbard: Arctic Packing, SAS, and the Snow Rule

Svalbard is the most extreme carry-on only challenge in this guide series. The Norwegian Arctic archipelago sits at 78° North — closer to the North Pole than to Oslo. Winter temperatures of -15°C to -25°C are common. The clothing required to survive outdoors here cannot be packed in a carry-on bag. It must be worn on the plane. Get that right and Svalbard carry-on only is genuinely workable. Get it wrong and you will either freeze or pay for checked baggage.

Airline Quick Reference

Airline	Route	Cabin Weight	Size Limit
SAS	Oslo (OSL)–LYR	7 kg	55 × 40 × 23 cm
Norwegian Air	Oslo (OSL)–LYR	10 kg	55 × 40 × 23 cm

The only commercial flights to Svalbard Airport Longyear (LYR) are from Oslo. SAS and Norwegian Air both operate the route. Norwegian Air's 10 kg allowance is more generous than SAS's 7 kg. Both carriers have the same size limits. If you have flexibility, Norwegian Air's extra 3 kg is meaningful when packing for Arctic conditions. SAS does not always enforce the 7 kg limit rigorously on this domestic Norway route, but you cannot plan around that — pack to the limit and wear everything else.

The Central Rule: Wear Everything Heavy

This is the most important piece of advice in this entire guide. Arctic outdoor gear does not fit in a carry-on bag. A heavy snowsuit, thick thermal layers, insulated snow boots, and a down parka together weigh 6–8 kg and take up enormous volume. None of that fits in a 55 × 40 × 23 cm bag alongside your other belongings.

Wear on the plane:

Heavy insulated parka or snowsuit jacket (your heaviest single item — wear it on board)
Insulated snow trousers (wear them — fold them over your lap or across your arm once seated)
Thermal base layer top and bottoms — wear under your travel clothes
Merino wool mid-layer
Thick insulated snow boots — wear them through the airport
Wool or thermal socks — wear on the plane
Thin inner gloves — in your pocket

Once airborne, stow the parka in the overhead bin and sit in your base layers and mid-layer. The aircraft cabin is warm. This is not unusual — Arctic travellers do this routinely.

Pack in your bag:

2 merino wool base layer tops
2 pairs of thermal socks
1 thin balaclava or neck gaiter
Wool or fleece hat and outer gloves (thin pair in pocket, thick pair in bag)
1 change of indoor clothes (Longyearbyen accommodation is very warm inside)
Toiletries and electronics

Bag Type: Soft Duffel, Not Wheeled Hard-Shell

Longyearbyen is a small town of around 2,400 people on the west coast of Spitsbergen. Its infrastructure is compact and rugged. Streets are a mix of gravel, compressed snow, ice, and uneven boards. Wheeled carry-on luggage is essentially useless in these conditions — wheels jam, crack, and refuse to roll on ice and gravel. A soft duffel bag or large backpack is the correct choice for Svalbard, and the same bag you would use as a carry-on. A 35–45 L soft duffel fits well within SAS and Norwegian's size limits and is dramatically easier to carry through Longyearbyen.

What Activities to Plan For

Dog sledding: No special gear required beyond what you are wearing. Operators provide outerwear in many cases — check with your tour operator. Your heavy parka and trousers are appropriate.

Snowmobiling: Similar to dog sledding. Helmets and outer suits are provided by tour operators. Wear your warm layers underneath.

Northern Lights viewing (October–February): You need your full Arctic kit. Temperatures at night can drop to -30°C during cold snaps. Guided tours take you by snowmobile or dog sled to dark sky locations. The guide provides safety briefing and warm beverages.

Midnight sun (April–August): Temperatures in July average around 6°C but can reach 10–12°C. Snow can still be present in spring. Packing requirements are lighter than winter but still heavier than a typical European summer trip. A windproof shell, warm mid-layer, and sturdy walking shoes are the minimum.

Polar bear safety: Outside Longyearbyen, guides carry rifles. As a tourist, you will not need to handle this — simply ensure every activity outside town is booked with a licensed operator.

Alcohol and Svalbard Customs

Svalbard's alcohol rules are a quirk. There is no VAT, which makes prices somewhat lower than mainland Norway. However, each resident and visitor has a monthly quota for purchasing alcohol at the Svalbard government store. Tourists visiting for a short period have access to their full monthly quota. The quota is not large and the overall cost is still higher than most European countries.

Duty-free allowances when returning to mainland Norway from Svalbard apply. Check current Norwegian Customs limits before stocking up on departure from Longyearbyen.

Bottom Line

Svalbard carry-on only demands a clear strategy: wear your snowsuit on the plane, pack base layers and accessories in a soft duffel, and treat the bag allowance as being almost entirely for non-clothing items. SAS at 7 kg and Norwegian Air at 10 kg are both workable if you follow this approach without exception. Do not attempt to pack your parka — you will fail. Wear it, store it overhead, and your bag will have plenty of room for everything else.
