Carry-On Only for Stockholm: Airlines, ARN vs NYO, and Packing Tips

Stockholm is a beautiful city for carry-on-only travel, but the airport situation is more complex than most European capitals. Arlanda (ARN) is the main international airport, well connected by express train. Ryanair flies to Skavsta (NYO) instead — a completely separate airport roughly 100 km south of the city. Understanding this distinction before you book is as important as knowing your airline's bag rules. Once in Stockholm, SAS's laptop bag exemption and the city's excellent public transport make the rest easy.

Airline Carry-On Rules at a Glance

Airline	Airport	Cabin Bag Size	Weight	Personal Item
SAS Scandinavian Airlines	ARN	55 × 40 × 23 cm	8 kg	Laptop bag (underseat)
Norwegian Air Shuttle	ARN	55 × 45 × 24 cm	10 kg	Small item (underseat)
Ryanair (Priority)	NYO	55 × 40 × 20 cm	10 kg	40 × 20 × 25 cm underseat
British Airways	ARN	56 × 45 × 25 cm	No weight limit	Handbag (underseat)

ARN vs NYO: The Airport Decision Matters

Arlanda Airport (ARN) is Stockholm's primary international airport, 40 km north of the city centre. The Arlanda Express train connects ARN to Stockholm Central Station in 20 minutes. It is fast and reliable but costs around 300 SEK single (roughly 25 EUR). The cheaper alternative is the Flygbussarna airport coach (around 100 SEK) or the commuter train (Pendeltåg), which takes about 40 minutes and is significantly cheaper.

Skavsta Airport (NYO) is where Ryanair flies to. It is approximately 100 km from Stockholm by road. Flygbussarna coaches connect it to Stockholm City Terminalen in around 80 minutes. When comparing a cheap Ryanair fare against SAS or Norwegian, always add the NYO coach cost and travel time to the calculation. The difference is often smaller than the headline fare gap suggests.

SAS at ARN: Laptop Bag Exemption

SAS allows a laptop bag or small personal item under the seat in addition to your 8 kg cabin bag. This is particularly useful for Stockholm trips where you might carry camera gear for the archipelago or the Fotografiska museum. Pack your laptop, camera, and cables in the underseat bag and your cabin bag will be well within 8 kg even with winter clothing.

SAS enforces weight limits at ARN check-in. Stockholm routes see active weight checks, particularly in winter when passengers tend to pack heavier. Budget a few hundred grams of margin below 8 kg.

Norwegian at ARN: Best Weight Allowance

Norwegian's 10 kg allowance on Stockholm routes is the most practical option for travelers who want to avoid weight anxiety. At 10 kg you can pack a week's worth of winter clothing, including a mid-layer, waterproof jacket, and full toiletry kit, without going over the limit. Norwegian's base Low Fare does not include an overhead cabin bag, so check your fare type at booking.

Ryanair at NYO: Do the Full Cost Calculation

Ryanair's fares to Skavsta look attractive but require careful cost addition. A basic Ryanair fare without priority boarding gives you only a small underseat item (40 × 20 × 25 cm). Adding priority boarding (which unlocks a full 55 × 40 × 20 cm overhead bag at 10 kg) costs extra. Then add the NYO–Stockholm coach fare (around 200 SEK each way). Once you account for these additions, the price gap between Ryanair and a sale SAS fare is often narrow.

Packing for Stockholm: Winter Is the Main Challenge

Swedish Winter Layering

Stockholm winters are cold and long. From November through March, temperatures range from minus 5 to plus 3 degrees Celsius. Snow is common. Pack accordingly:

Layer	Item	Notes
Base	Thermal top and leggings	Merino preferred, odour-resistant
Mid	Fleece or wool jumper	Packs compact
Outer	Insulated waterproof jacket	Wear on the plane
Feet	Waterproof ankle boots	Essential on snow and slush

Wearing your heaviest jacket and boots during travel removes the bulkiest items from your bag weight entirely. An insulated jacket worn on board can weigh 1.5 to 2 kg — the same as a full day's worth of clothing.

Summer Packing

Stockholm summers (June–August) are mild to warm, averaging 18–24 degrees. Late evenings stay light until near midnight. A light rain layer and a mid-layer for cool evenings are all you need in addition to warm-weather basics.

ABBA Museum and Gamla Stan

The ABBA Museum on Djurgården is one of Stockholm's most visited attractions. It involves a lot of standing and walking through exhibits over 1–2 hours. Comfortable trainers are the right footwear.

Gamla Stan (the Old Town) is Stockholm's historic island district. The streets are medieval, narrow, and cobblestoned. Comfortable shoes matter here as much as in any historic European district. The Royal Palace, Storkyrkan cathedral, and the Nobel Museum are all within Gamla Stan. Plan at least a half-day.

Archipelago Day Trips

The Stockholm archipelago spans over 30,000 islands east of the city. Waxholmsbolaget ferries depart from Strömkajen near the Grand Hotel. Popular day trips include:

• Vaxholm: 1–1.5 hours by ferry, the gateway to the archipelago, historic fortress
• Sandhamn: 3+ hours, remote outer archipelago island, popular in summer
• Fjäderholmarna: 25 minutes, the nearest island cluster, good for a short trip

All are manageable as day trips from central Stockholm without extra luggage. Bring a small daypack inside your carry-on to use on island days.

Arlanda Airport (ARN): Practical Notes

• Arlanda Express: 20-minute non-stop to Stockholm Central, runs every 15 minutes. Most convenient but not cheapest.
• Pendeltåg + airport rail link: Slower but significantly cheaper if you buy a standard SL zone ticket.
• Security: Standard EU liquids rules (100 ml per container in a 1-litre bag). Arrive 2 hours before departure for European flights and 2.5 hours for long-haul.
• Terminal layout: Terminal 5 handles most international and intercontinental flights. Terminals 2 and 4 handle some domestic and short-haul European routes. Check your terminal on your boarding pass.

Practical Tips

• Book Norwegian for winter weight flexibility. Ten kilograms removes most of the anxiety from packing a week of winter clothes. SAS's 8 kg requires more careful planning in winter.
• Choose ARN over NYO unless the price gap is large. The convenience advantage of the Arlanda Express over an 80-minute Skavsta coach ride is significant.
• Wear your coat and heaviest boots on the plane. This is the single most effective weight-saving strategy for winter travel.
• Pack merino base layers. They compress small, resist odour, and work as a base layer or standalone top depending on temperature.
• Fotografiska is open late. Stockholm's major photography museum is open until 23:00 on many nights. Plan a late evening visit to avoid daytime crowds, wearing your daypack rather than managing a full bag.

The Bottom Line

Stockholm is carry-on friendly once you sort the airport question. Fly SAS or Norwegian into Arlanda and save yourself the 80-minute Skavsta coach ride unless the Ryanair price difference is genuinely large after adding all costs. SAS's laptop bag exemption is useful; Norwegian's 10 kg limit is the most generous. In winter, wear your coat on the plane — it is the most important packing decision you will make.
