SFO to Reykjavik: what the nonstop question actually settles

Planning sfo to Reykjavik around a single nonstop flight is the first mistake this route makes for a traveller. Keflavik's own airport authority lists the US cities with direct service to Iceland, and San Francisco is not one of them. The trip settles instead on a connection through an East Coast gateway, and the choice of gateway is what decides total travel time. Icelandair and its partner carriers route West Coast passengers onto a second flight, most often through Boston, New York or Denver, before the transatlantic leg to Keflavik. Nothing about that requires an overnight stop, but it does mean building a layover into the itinerary from the outset rather than discovering it at check-in.

What the West Coast route map actually offers

A traveller comparing lax to Reykjavik against the San Francisco option is often looking for the same thing: any nonstop out of California to Keflavik. Isavia's published destination list, checked 2026-09-08, does not carry a nonstop from Los Angeles either. The nearest US nonstops sit on the East Coast, in the Midwest and on the West Coast only as far north as Seattle, which does have a direct service according to the same list.

That leaves Seattle as the closest true nonstop gateway to Iceland for anyone starting on the Pacific coast, with a published flight time of 7 hours 30 minutes. A passenger starting in San Francisco or Los Angeles instead connects onto a flight already headed to Keflavik from one of the cities Isavia lists, rather than booking two separate transatlantic-length legs.

Redoing the search by city name rarely changes the outcome, because the underlying route map is the same regardless of which West Coast airport a traveller starts from. The difference between airports shows up in domestic connection times and fares, not in whether a nonstop exists.

Building a connecting itinerary

Searching flights sfo to Reykjavik in a booking tool usually returns a one-stop or two-stop itinerary rather than a single long-haul segment, because no carrier currently sells a nonstop out of San Francisco to Keflavik. The routing typically runs through a domestic connection to one of the gateway cities Isavia lists as having direct KEF service, most commonly Boston, Denver or Seattle, before the transatlantic segment begins.

The total elapsed time on a connecting itinerary is the domestic leg plus a layover plus the published transatlantic block time from whichever gateway is used. Denver's own nonstop to Keflavik runs 8 hours 5 minutes on its own, and Seattle's runs 7 hours 30 minutes, so a San Francisco departure adds a domestic segment and a connection window on top of either of those figures.

Choosing the gateway with the shortest domestic hop from San Francisco, rather than the shortest transatlantic block time on paper, is usually what keeps total travel time down on this route.

San Diego and other Southern California starting points

A search for san diego to Reykjavik runs into the same limit as San Francisco and Los Angeles: no Southern California airport appears on Isavia's list of US cities with a nonstop to Keflavik, checked 2026-09-08. A traveller from San Diego connects domestically to a gateway city first, exactly as a San Francisco traveller does, and from there picks up the same transatlantic options.

This matters for how the itinerary gets built and priced. Rather than searching for a single flight number, the practical approach is to pick the domestic connection city first, since that decision affects both layover length and fare more than the transatlantic segment does once a gateway with direct KEF service is chosen.

Seattle, Denver, Chicago, Boston, New York and Washington DC are the West Coast-reachable US gateways with a nonstop to Keflavik on Isavia's current list, and any of them can serve as the connection point for a Southern California departure.

Why no direct option exists yet

Anyone searching for direct flights from sfo to Reykjavik is checking for something that does not currently appear on the airport operator's own route map. Isavia's destinations page, checked 2026-09-08, lists 84 nonstop airports across 25 countries served from Keflavik, and 16 of those are in the United States. San Francisco is not among them, and neither is any other airport in Northern or Southern California.

The 16 US nonstop cities run from the East Coast through the Midwest and Mountain West to Seattle on the Pacific coast, with Detroit and Pittsburgh flying only in summer and Miami only in winter. A route from San Francisco would need to appear on this same list to count as direct, and as of the most recent check it does not.

Booking a connecting itinerary through one of the 16 listed gateways remains the way to reach Keflavik from Northern or Southern California.

Getting from Keflavik into Reykjavik

Landing at Keflavik after a long connecting itinerary leaves one more leg before the trip properly starts: the airport sits well outside Reykjavik itself, 3 km from Keflavík town and about 47.2 km (29.3 miles), a 47-minute drive, from central Reykjavik. The Flybus runs from the terminal to the BSÍ bus terminal in Reykjavik in around 45 minutes for a one-way fare of 3,999 ISK, with a return priced at 7,298 ISK and a child fare of 2,000 ISK for ages 6 to 15.

A fixed-price taxi from Hreyfill costs 22,500 ISK for one to four passengers, rising to 29,250 ISK for five to eight; metered rides from other companies typically run 15,000 to 25,000 ISK. Travellers arriving after a full day of connections often find the bus the less demanding option, since it does not require negotiating a fare on arrival.

American and British passport holders need no visa for stays up to 90 days in any 180-day period under the Schengen rule, though passports must be valid three months beyond the departure date. The US State Department's Iceland country page and the UK FCDO's Iceland travel advice cover entry requirements in more detail before departure.
