Carry-On Only for Iceland: Airlines, Keflavík, and Packing Tips

Iceland presents the hardest carry-on packing challenge of any popular European destination. The weather demands serious outdoor gear — waterproof shells, thermal layers, and sturdy footwear — that takes up disproportionate space in a standard 55 × 40 × 20 cm bag. The solution is to wear it, not pack it. Get that right and Iceland is very manageable carry-on only.

Airlines Flying to Iceland

Icelandair (23 kg checked bag included on most routes): Icelandair is Iceland's flag carrier and includes a 23 kg checked bag on most transatlantic routes and many European routes. On a pure policy basis, you do not need to travel carry-on only on Icelandair — the free checked bag is a genuine advantage for gear-heavy outdoor trips. That said, many Iceland visitors still choose carry-on only because Keflavík's baggage claim adds meaningful time to what is already a long transfer to Reykjavík. The choice depends on your gear volume and schedule.

Play Airlines (no free carry-on on base fare): Play is an Icelandic ultra-low-cost carrier operating primarily transatlantic routes from the US, UK, and select European airports. Its pricing model is similar to Ryanair — the base fare includes only a small 42 × 32 × 25 cm personal item. A full overhead cabin bag must be purchased as an add-on. Play's base fares can appear very competitive until you add the bag cost, so compare total prices rather than headline fares when deciding between Icelandair and Play.

Keflavík International Airport (KEF)

Keflavík is Iceland's primary international airport and is small, modern, and fast by European standards. Key practical details:

Fast security: KEF security clears quickly. A two-hour buffer before departure is more than sufficient and 90 minutes is typically comfortable. The airport does not have the volume or complexity of major European hubs.

Long transfer to Reykjavík: The airport is 50 km from the city and sits on the Reykjanes Peninsula. Flybus and other coach services cover the route in 45–60 minutes depending on your accommodation's location. Some services include a drop-off directly to downtown hotels. This transfer cost — in both time and money — is one of the strongest arguments for carry-on only travel to Iceland: skipping baggage claim saves real time at the end of a long flight.

Duty-free is prominent: Keflavík has one of Europe's most-discussed duty-free halls on arrival. Alcohol is very expensive in Iceland and the duty-free limit for arrivals is 1 litre of spirits or 6 litres of beer (or combinations). Many visitors buy their full allowance on arrival. Check current Icelandic customs limits before you travel, and note that duty-free alcohol must fit within your total baggage allowance.

Packing for Iceland: The Outdoor Gear Challenge

Wear your gear on the plane: This is the central carry-on strategy for Iceland and the most important thing in this guide. The gear required for Icelandic weather — waterproof shell jacket, thermal mid-layer (fleece or down), merino wool base layer — is bulky and heavy when packed. Worn to the aircraft, it takes up zero bag space and weighs nothing against your allowance. Wearing a merino base layer, a down or fleece mid-layer, and a waterproof shell on the plane saves approximately 3–4 kg of carry-on weight and frees up significant space for everything else. Stow the shell in the overhead bin during the flight.

Merino wool base layers: Merino is the best material for Iceland travel on a carry-on budget. It is warm, moisture-wicking, odour-resistant, and fast-drying. One merino base layer worn on the plane and one in the bag covers most multi-day trips without needing to pack heavyweight alternatives. Merino packs small and handles Iceland's damp, windy conditions better than cotton or synthetic alternatives.

Waterproof shell jacket — wear it, do not pack it: Iceland's weather changes rapidly and rain arrives with little warning even on otherwise clear days. A waterproof shell with sealed seams is essential. Wear it to the airport and on the plane. This is the single item that most sabotages a carry-on attempt when packed — shell jackets are light but voluminous.

Compact sleeping bag liner for sleeping pod tours: If your Iceland itinerary includes a Northern Lights tour that ends at a remote sleeping pod facility or mountain hut, a compact sleeping bag liner adds warmth without the volume of a full sleeping bag. Pod facilities typically provide bedding, but a liner adds significant warmth at minimal pack weight.

Buy outdoor gear locally: Reykjavík has a good thrift store and second-hand market network. The Kolaportið flea market (weekends) and several charity shops around the city sell outdoor gear — fleece jackets, waterproof trousers, and base layers — at reasonable prices. Buying a replacement or supplementary layer in Reykjavík after arrival removes the pressure to pack everything from home. If you find cheap gear locally, you can also leave it behind on the return flight rather than filling your carry-on with it.
