Carry-On Only for Reykjavik: Packing Guide & Airline Rules

Reykjavik, Iceland's capital, offers two completely different travel experiences depending on when you visit: summer brings midnight sun, puffins, and green lava fields; winter offers northern lights, dramatic snowscapes, and geothermal pools steaming in the dark. Both seasons are excellent. Both reward carry-on packing, because the activities — outdoor adventure, geothermal bathing, glacier walks — require technical layers rather than bulky formal wear, and technical layers compress well.

Airline Quick Reference

Read the route-specific allowance below before choosing a bag. A capacity label in litres does not establish compliance.

Icelandair's Carry-On Policy in Practice

Icelandair includes one 55×40×20 cm main bag, including wheels and handles, plus a 40×30×15 cm personal item on all tickets, including Economy Light. Saga Premium Flex includes two main bags. The weight limit is 10 kg per main bag internationally, but 6 kg on domestic Iceland flights and flights to Greenland and the Faroe Islands. The current overview and older domestic page differ on width (40 versus 35 cm); confirm regional bookings. No relaxed-enforcement assumption applies.

Keep essentials accessible if a bag is collected for the hold. Confirm stopover baggage handling separately.

Packing for Iceland: The Layering System

Iceland's weather is famously unpredictable — locals say you can experience all four seasons in one day. This is not exaggeration. The system that works:

Base layer (worn, not packed):

• Merino wool or synthetic moisture-wicking top and leggings/long underwear
• Wear this on the plane; it adds zero bag weight

Mid layer:

• Fleece or down insulating jacket that compresses into a stuff sack
• This is your warmest layer for glaciers and winter activities

Outer layer:

• Hardshell waterproof/windproof jacket — non-negotiable regardless of season
• Pack a second packable rain layer or use your outer shell as the sole waterproof

Everything else for 7 nights:

• 2–3 base layer tops (merino wool dries quickly and can be worn multiple times)
• 1–2 pairs of convertible or quick-dry trousers
• 1 swimsuit (mandatory — see below)
• Thermal underlayers for legs if visiting in winter
• Merino wool socks (3 pairs minimum)
• Waterproof hiking boots or trail runners (wear on the plane)

Merino wool is the ideal fabric for Iceland — it regulates temperature, resists odour, dries quickly, and compresses far smaller than cotton. A week of merino layers packs noticeably lighter.

The Swimsuit Is Non-Negotiable

Iceland's geothermal pools are central to the local culture and a must-do for any visitor. You need a swimsuit for:

• Blue Lagoon (Grindavík, near KEF): The world's most famous geothermal spa; towels and robes are rented, swimsuit is required
• Sky Lagoon (Reykjavik): A newer luxury alternative with ocean views
• Sundlaugar (public swimming pools): Reykjavik has several public pools — locals use them daily, entry costs around €10, towels rented on site

All venues rent towels. A swimsuit is not rentable — pack one.

Golden Circle and Activity Planning

Most visitors do at least one major day tour. Common activities:

• Golden Circle: Thingvellir National Park, Geysir hot spring, Gullfoss waterfall — expect waterfall spray; waterproof layer essential
• Northern Lights (winter): Requires darkness and clear skies; guided tours depart from the city
• Glacier walks: Crampons and helmets provided; bring warm layered clothing underneath
• Whale watching: Cold and windy on the water — wear all your warm layers

All are day trips. A 15–20 L daypack inside your main bag covers activity needs.

Airport to City: The Important 50 km Gap

Keflavík International Airport (KEF) is not in Reykjavik — it is 50 km southwest of the city on the Reykjanes Peninsula. This surprises many first-time visitors.

• FlyBus / Airport Express: Shuttle buses run to the BSI bus terminal in Reykjavik and can be pre-booked to drop at major hotels. Journey time: 45–55 minutes. Cost: roughly €25–30 each way.
• Taxi: Approximately €100–120 one way — rarely justified
• Rental car: Most practical if you plan to drive the Ring Road; pick up at KEF

Allow extra time for this transfer when planning arrival and departure logistics.

Bottom Line

Build the Iceland packing list around suitable layers, then measure and weigh the full bag. A litre capacity does not guarantee compliance. Check every flight, especially regional legs with a 6 kg allowance.
