Book Flights to Reykjavik, Iceland
Reykjavik sits almost exactly midway between North America and continental Europe, a geography Icelandair turned into a deliberate strategy: connect through Keflavík and add up to seven nights in Iceland for free. The result is a compact, colorful capital that has become one of the world's easiest add-on destinations.
Icelandair dominates the route with the widest network from North America and Europe alike, PLAY Airlines undercuts on price, and several US carriers add seasonal summer service. FareOptic compares every routing into KEF.

Why Visit Reykjavik?
A milky lagoon born from a power plant's runoff, a canyon where two continents are visibly pulling apart, a parliament that first met in 930 AD, and Northern Lights reachable on a short drive from the airport.
The Blue Lagoon and Iceland's Geothermal Bathing Culture
A Milky Turquoise Geothermal Spa Formed, Somewhat Accidentally, by Runoff From an Adjacent Power PlantThe Blue Lagoon, Iceland's single most internationally recognized attraction, is a large geothermal spa complex situated in a lava field on the Reykjanes Peninsula between Keflavík Airport and Reykjavík itself, making it a genuinely convenient stop either immediately upon arrival or before departure given its location directly along the standard airport-to-city route. Its distinctive milky blue-white water and silica-rich mineral content, often marketed for skin health benefits, originated from a somewhat unplanned source: the lagoon formed from mineral-rich geothermal wastewater discharged by the adjacent Svartsengi power station, a combined heat and power plant that draws superheated water from deep underground, and swimmers began using the naturally forming pool for its warmth and mineral content in the 1980s before it was later developed into the highly commercialized, purpose-built spa facility it is today, complete with swim-up bars, silica mud mask stations and a range of premium package tiers. Advance booking is essential rather than optional, since the Blue Lagoon operates on a timed-entry ticketing system that regularly sells out, particularly during peak summer and around major holiday periods.
Alternatives to the Blue Lagoon, and the Reykjanes Volcanic Activity
Because the Blue Lagoon has become both expensive and heavily touristed, with some visitors and travel writers noting it feels considerably more commercial and crowded than Iceland's more low-key traditional geothermal pools, a range of alternative geothermal bathing experiences have grown in popularity, including the Sky Lagoon closer to Reykjavík itself with its own infinity-edge ocean view design, and various municipal swimming pools throughout Reykjavík and across Iceland that locals actually use as genuine community gathering spaces at a fraction of the Blue Lagoon's cost, offering visitors a more authentic sense of how geothermal bathing actually functions in ordinary Icelandic daily life rather than as a tourist spectacle. It's also worth being aware that the Reykjanes Peninsula, where the Blue Lagoon sits, has experienced a series of volcanic eruptions and significant seismic activity in recent years as part of a broader reawakening of volcanic systems in the region after centuries of dormancy, which has at various points led to temporary closures of the Blue Lagoon itself and the nearby town of Grindavík due to lava flow risk — checking current volcanic activity status and any related closures before finalizing plans around this specific attraction is genuinely important given the situation has remained periodically active.
The Golden Circle — Iceland's Most Visited Day Trip Route
Þingvellir National Park, the Geysir Geothermal Area and Gullfoss Waterfall, All Reachable in a Single Day From ReykjavíkThe Golden Circle is the most-visited touring route in Iceland, a roughly 300-kilometer loop from Reykjavík covering three major natural and historical sites that between them showcase much of what draws visitors to Iceland in the first place, making it the default first-day excursion for the large majority of visitors and one of the most heavily trafficked tourist circuits in the country as a result. Þingvellir National Park holds profound significance on two entirely different levels: geologically, it sits directly within the visible rift valley where the North American and Eurasian tectonic plates are actively pulling apart, allowing visitors to literally walk through a canyon marking the boundary between two continental plates; historically, it was the site of the Althing, Iceland's parliament and one of the oldest surviving parliamentary institutions in the world, established here in 930 AD and continuing to meet at this location for centuries afterward, making the site simultaneously a landmark of plate tectonics and of early democratic governance. The Geysir geothermal area gives the English language the word 'geyser' itself, taken from the Icelandic name of the largest historic hot spring here, Geysir, though the more reliably active performer today is the smaller neighboring geyser Strokkur, which erupts every several minutes to a height of several dozen feet.
Gullfoss and Extending the Circle Further
Gullfoss, the third major Golden Circle stop, is a powerful two-tiered waterfall on the Hvítá river that drops into a dramatic, deep canyon, and its scale and the sheer volume of water passing through make it one of Iceland's most visually striking waterfalls, particularly on clear days when rainbows commonly form in the mist thrown up by the falls. Because the standard Golden Circle route can be completed comfortably in a single day whether self-driving or on an organized tour, many visitors extend or combine it with additional nearby stops not part of the traditional three-site core, including the Kerið volcanic crater lake, the Fontana geothermal baths in the town of Laugarvatn, or a detour to Secret Lagoon, a smaller, less commercialized geothermal pool that predates the Blue Lagoon's development and offers a more low-key bathing alternative directly along the Golden Circle route itself, giving visitors who want to combine geothermal bathing with the classic sightseeing circuit a convenient option without a separate dedicated trip to the Blue Lagoon or Sky Lagoon.
The Northern Lights and Iceland's Winter Darkness
Iceland's High Latitude and Minimal Light Pollution Outside Reykjavík Make It One of the World's Most Accessible Aurora Borealis DestinationsIceland's position just south of the Arctic Circle, combined with generally low light pollution across most of the country outside central Reykjavík itself, makes it one of the more consistently accessible destinations in the world for viewing the aurora borealis, and the northern lights have become a major driver of Iceland's winter tourism season specifically, with many visitors timing trips deliberately around the viewing season running roughly from late August or September through mid-to-late April, when nights are dark enough for the aurora to be visible against a clear sky. Iceland's genuinely useful advantage over some other aurora destinations is accessibility and infrastructure: unlike more remote arctic viewing locations that can require significant additional travel and logistics, Iceland's aurora season overlaps with its main international airport, established tour infrastructure, and a road network that in many cases allows visitors to simply drive a relatively short distance outside Reykjavík's own urban light pollution to reach genuinely dark viewing conditions, making organized evening aurora tours from the city a well-developed and widely available product throughout the season.
Realistic Expectations and the Iceland Winter Daylight Trade-off
As with aurora viewing anywhere in the world, actual sightings depend entirely on the combination of real-time geomagnetic activity, clear skies and reasonably dark conditions, meaning no operator or destination can guarantee a sighting on any given night regardless of season, and checking Iceland's official aurora forecast service, which combines cloud cover and geomagnetic activity predictions into a single accessible tool, is far more useful than assuming any winter visit will automatically include a viewing. It's also worth understanding the genuine trade-off involved in visiting Iceland specifically for winter aurora viewing: the same winter darkness that makes aurora viewing possible also means dramatically reduced daylight hours, with parts of December offering only around four to five hours of weak daylight around midday, which significantly limits daytime sightseeing time and requires adjusting expectations and itinerary pacing accordingly compared to a summer visit, when the situation reverses entirely and Iceland instead offers nearly 24-hour daylight around the summer solstice, ruling out aurora viewing entirely but maximizing time for the country's extensive outdoor sightseeing.
The South Coast — Waterfalls, Black Sand Beaches and Glacier Country
A Single Coastal Road Trip Route Covering Some of Iceland's Most Dramatic and Widely Photographed Natural LandscapesIceland's South Coast, extending along the Ring Road roughly from Reykjavík toward the country's southeastern glacier region, has become the second most popular touring route in the country after the Golden Circle, and it can be explored as anything from a long single-day trip to a multi-day journey depending on how far along the coast a visitor travels and how many stops they build in. Seljalandsfoss and Skógafoss, two of Iceland's most photographed waterfalls, sit relatively close together along the route: Seljalandsfoss is notable for a walking path that circles behind the falling water itself, a genuinely distinctive vantage point rarely available at major waterfalls elsewhere, while Skógafoss offers a more classically powerful, wide single-drop cascade with a staircase climbing to a viewing platform above it. Reynisfjara, a striking black sand beach near the village of Vík backed by dramatic basalt column rock formations, is one of the most visually dramatic beaches in Iceland and frequently appears in international media and film, but it also carries a genuine and well-documented safety hazard from unpredictable, powerful 'sneaker waves' that have caused fatalities among visitors who ventured too close to the waterline without understanding the risk — heeding posted warnings and maintaining significant distance from the water's edge is essential rather than a formality.
The Glacier Lagoons Further East
Further along the South Coast, roughly a full day's drive from Reykjavík, Jökulsárlón Glacier Lagoon is a striking glacial lake filled with icebergs that have calved off the adjacent Breiðamerkurjökull glacier and drift slowly toward the ocean, with some pieces washing up on the adjacent black sand beach in a phenomenon that has earned it the nickname Diamond Beach for the way ice chunks glitter against the dark sand, making this stretch of coastline a genuinely worthwhile if longer add-on for visitors with several days available rather than a rushed single-day itinerary. Because the full South Coast, particularly extending to Jökulsárlón, represents a substantial driving distance and full day or more of travel time in each direction from Reykjavík, most visitors either commit to at least an overnight stay somewhere along the route to avoid an exhausting same-day round trip, or join a longer multi-day organized tour, and self-drivers should factor in Iceland's sometimes challenging weather conditions, particularly outside summer months, when road conditions and driving times can be significantly affected by wind, snow and ice regardless of the route's overall popularity and generally well-maintained road surface.
Reykjavík Itself — the World's Northernmost Capital of Its Size
A Compact, Colorful City Center Anchored by Hallgrímskirkja Church and a Genuinely Small Population for a National CapitalReykjavík, with a city population in the tens of thousands and a wider metropolitan area holding the significant majority of Iceland's total national population of roughly 400,000, is frequently cited as the world's northernmost capital city of its size, and its remarkably compact, walkable downtown core reflects that modest scale, allowing visitors to cover most of the central sightseeing on foot over a day or two without needing significant transportation planning within the city itself. Hallgrímskirkja, the tall, distinctively angular concrete church dominating the city's skyline, was designed to architecturally evoke Iceland's basalt lava column rock formations found throughout the country's natural landscape, and its observation tower, accessible for a fee, offers the best elevated view over Reykjavík's colorful low-rise rooftops out toward the surrounding mountains and coastline. The downtown area's brightly painted corrugated metal building facades, a distinctly Icelandic architectural adaptation using an inexpensive, weather-resistant material well suited to the harsh North Atlantic climate, give the city center a genuinely distinctive and photogenic visual character quite different from typical European capital architecture.
Reykjavík's Food Scene and Practical City Notes
Reykjavík's food scene has developed considerably in recent years alongside the broader tourism boom, ranging from genuinely excellent New Nordic fine dining establishments drawing on fresh Icelandic seafood and lamb to more casual, distinctly local options including the famous hot dog stand Bæjarins Beztu Pylsur, a genuinely humble, decades-old stall that has nonetheless drawn international visitors and celebrity patronage for its distinctly Icelandic-style hot dog topped with crispy fried onions, ketchup, sweet brown mustard and remoulade. Visitors should be aware that Iceland is consistently among the most expensive countries in the world for food, accommodation and general tourism spending, a genuine budgeting consideration that surprises many first-time visitors expecting costs more comparable to mainland Europe, and planning a realistic daily budget with this cost reality in mind — rather than assuming Icelandic prices will resemble those of nearby European countries — will help avoid unpleasant surprises partway through a trip.
How to Find Cheap Flights to Reykjavik
Use Icelandair's Free Stopover to Add Iceland to a Europe Trip at No Extra Airfare
If you're already planning a flight to continental Europe or the UK, check whether routing through Reykjavík on Icelandair and adding a stopover of up to seven nights costs anything extra over a direct flight — it very often does not, since Icelandair prices the stopover as simply choosing a different routing on the same ticket rather than an add-on. This is one of the more genuinely useful 'free' travel opportunities still available on a major airline.
Compare Icelandair Against PLAY Airlines on the Same Route and Dates
PLAY Airlines offers a genuine low-cost alternative to Icelandair on many of the same North American and European connecting routes through Keflavík, but its base fares exclude checked bags and other extras standard on Icelandair. Calculate your full realistic itinerary cost, including any bags you'll need for a trip likely involving cold-weather and outdoor gear, before assuming PLAY's lower headline fare is actually cheaper for your specific trip.
Book Well Ahead for Winter Aurora Season and Summer Peak Alike
Iceland's winter aurora season (roughly September through April) and summer peak season (June through August, when nearly 24-hour daylight maximizes sightseeing time) both drive strong demand and higher prices. Shoulder seasons in spring and early fall can offer a reasonable middle ground of lower prices with still-decent conditions, though with less daylight than summer and less aurora reliability than deep winter.
Check Reykjanes Peninsula Volcanic Activity Status Before Finalizing Blue Lagoon Plans
The Reykjanes Peninsula, where the Blue Lagoon and Keflavík Airport itself are both located, has experienced a series of volcanic eruptions and significant seismic activity in recent years. This has periodically led to temporary closures of the Blue Lagoon and nearby areas. Check current volcanic activity status and any related closures shortly before your trip rather than assuming the situation from a past season still applies.
Airlines Flying to Reykjavik (KEF)
Icelandair
Iceland's Flag Carrier, and the Airline That Invented the Modern Free Stopover as a Deliberate Marketing StrategyIcelandair operates the largest network into Keflavík by a wide margin, flying nonstop from a substantial list of North American cities including New York, Boston, Newark, Chicago, Seattle, and various seasonal additions, alongside a similarly broad European network from London, Paris, Frankfurt, Amsterdam and many more, all funneling through its Reykjavík hub in a classic transatlantic connecting-hub model that leverages Iceland's genuinely useful mid-Atlantic geographic position roughly midway between North America and continental Europe. The airline's defining and widely imitated innovation is its stopover program, formally allowing passengers connecting through Keflavík to break their journey in Iceland for up to seven nights at no additional airfare, a policy Icelandair has promoted aggressively for decades specifically to build Iceland's tourism industry using its own connecting traffic, and one that has been credited by many industry observers as a major contributing factor in Iceland's tourism boom over the past 15 years.
Key Routes
Nonstop to KEF from JFK, EWR, BOS, ORD, SEA, and seasonal North American cities including various others added and adjusted by season; nonstop from LHR, CDG, FRA, AMS and dozens of other European cities; the free multi-night stopover program applies to nearly all connecting itineraries through KEF and requires no separate booking beyond selecting the stopover option during ticket purchase
PLAY Airlines & Low-Cost Transatlantic Competition
A Newer Icelandic Low-Cost Carrier Built Explicitly to Compete With Icelandair on the Same Transatlantic Connecting ModelPLAY Airlines, an Icelandic low-cost carrier launched in 2021 by former WOW air executives following that airline's 2019 collapse, operates a similar transatlantic connecting model through Keflavík but at a lower-cost, more unbundled fare structure, offering nonstop service between Iceland and a number of North American and European cities with the base fare typically excluding checked bags and other add-ons standard on Icelandair. PLAY has positioned itself specifically as the budget alternative for travelers whose primary goal is the cheapest possible transatlantic connection via Iceland rather than Icelandair's more premium positioning and stronger loyalty program, and the resulting competition between the two Icelandic carriers has generally kept fares on the Iceland connecting route more competitive than they might otherwise be with only a single dominant national carrier. As with any ultra-low-cost booking, calculating the full cost including bags and seat selection against Icelandair's more inclusive fares is essential before assuming PLAY is automatically cheaper for a specific itinerary.
Key Routes
PLAY Airlines connecting service through KEF between select North American cities and European destinations; base fares typically exclude checked bags and seat selection — calculate full itinerary cost before comparing against Icelandair; PLAY has periodically adjusted its North American gateway cities, so verify current routes for your specific origin
Delta, United, American & Other Direct Seasonal Service
Several US Legacy Carriers Have Added Direct Summer-Season Service to Keflavík Given Iceland's Sustained PopularityGiven Iceland's sustained tourism growth over the past decade and a half, several US legacy carriers have periodically added direct nonstop service to Keflavík from additional gateway cities beyond what Icelandair alone offers, typically operating on a seasonal basis concentrated in the busier summer travel months when demand is highest, providing more direct routing options and airline loyalty program earning potential for travelers who prefer to fly their preferred US carrier's metal directly rather than connecting through Icelandair's or PLAY's hub-and-spoke model. Because this seasonal capacity has fluctuated over recent years as airlines adjust their international route networks based on demand and broader industry conditions, checking current direct service availability for your specific dates and gateway city, rather than assuming a particular US carrier's Iceland route from a past season is still operating, is worthwhile when planning a trip.
Key Routes
Various US legacy carriers have operated seasonal direct KEF service from additional US gateways beyond Icelandair's network, concentrated in summer months — verify current seasonal route operation for your specific origin and travel dates before booking

Frequently Asked Questions on Travel to Reykjavik
Everything you need to know about booking cheap flights to Reykjavik, Iceland
What airport serves Reykjavik?
Keflavík International Airport (IATA: KEF) sits roughly 45 to 50 minutes southwest of central Reykjavík. It is Iceland's main international gateway, dominated by Icelandair's extensive North American and European network, alongside PLAY Airlines and periodic seasonal service from US legacy carriers.
What is Icelandair's stopover program?
A long-standing policy allowing passengers connecting through Keflavík on a transatlantic itinerary to break their journey in Iceland for up to seven nights at no additional airfare, simply by selecting the stopover option when booking. It has been widely credited as a major factor in Iceland's tourism growth over the past 15 years and remains one of the more genuinely useful free travel perks still offered by a major airline.
When is the best time to see the Northern Lights in Iceland?
The viewing season runs roughly late August or September through mid-to-late April, when nights are dark enough. Actual sightings depend on clear skies and real-time geomagnetic activity — check Iceland's official aurora forecast rather than assuming any winter visit guarantees a sighting. Be aware that deep winter also means very limited daylight, sometimes only four to five hours in December, which cuts into daytime sightseeing time.
Is the Blue Lagoon worth visiting?
It's Iceland's most famous attraction and genuinely striking, but also expensive and heavily touristed, and it requires advance timed-entry booking since it regularly sells out. Many visitors find alternatives like the Sky Lagoon or Iceland's ordinary municipal swimming pools offer a more authentic, far cheaper geothermal bathing experience. Also check current volcanic activity status on the Reykjanes Peninsula, where the Blue Lagoon sits, since periodic eruptions have caused temporary closures in recent years.
What is the Golden Circle?
Iceland's most-visited day trip route, a roughly 300-kilometer loop from Reykjavík covering Þingvellir National Park (site of the rift valley between two tectonic plates and Iceland's original 930 AD parliament), the Geysir geothermal area (source of the English word 'geyser'), and Gullfoss, a powerful two-tiered waterfall. It's easily done in a single day, whether self-driving or on an organized tour, and is the default first excursion for most visitors.
Is Iceland expensive?
Yes — Iceland is consistently ranked among the most expensive countries in the world for food, accommodation and general tourism spending, which surprises many first-time visitors. Budgeting realistically for this, rather than expecting costs comparable to mainland Europe, will help avoid unpleasant surprises. Icelandair's free stopover and the ability to self-drive and self-cater to some degree can help offset costs somewhat.
Do US citizens need a visa for Iceland?
No. Iceland is part of the Schengen Area (though not an EU member), so US passport holders may visit for up to 90 days in any 180-day period without a visa. Your passport must be valid for at least three months beyond your intended departure. The EU's ETIAS travel authorization, comparable to the US ESTA, has been in development and will eventually apply to visa-exempt travelers, so check its current status before you travel.
What currency is used in Iceland?
The Icelandic króna (ISK). Iceland has a highly card-friendly culture — cards are accepted almost everywhere, including small purchases, and carrying significant cash is generally unnecessary. Contactless payment is widely supported.
