Cheap Flights from San Francisco to Europe

San Francisco is the West Coast airport that goes south.

That sounds like a small observation and it is the whole story of this gateway. Seattle and Portland are cheap to Scandinavia because the great-circle route over the pole is genuinely short from the Pacific Northwest. San Francisco sits 900 miles further down the coast, loses that geometry, and gets something else instead: broad, even, unspectacular access to the Mediterranean.

The flattest cheap end of any major gateway

Destination	Round trip	National rank for that city
Malta	$611	6th of 26
Seville	$617	6th of 26
Stockholm	$617	14th of 26
Dublin	$618	4th of 26
Porto	$623	5th of 26
Barcelona	$626	12th of 26
Madrid	$627	8th of 26
Vienna	$627	3rd of 26
Lisbon	$630	5th of 26
Naples	$633	3rd of 26

Ten cities inside $22. Malta at the top and Naples at the bottom of that list are separated by less than the price of a checked bag on most transatlantic tickets.

No other gateway we price has a cheap end this compressed. Boston's ten cheapest span $165. Raleigh's span $168. San Francisco's span $22, which means the usual advice — be flexible about where you land, it is worth hundreds — is worth almost nothing here. From SFO, flexibility across the cheap end buys you a rounding error.

What it does buy is choice without penalty. If you want Seville rather than Dublin, that preference costs you $1.

Six of the ten are Mediterranean

Malta, Seville, Porto, Barcelona, Madrid, Lisbon. Add Naples and Vienna and the shape is unmistakable: this is a southern-Europe airport.

Compare it to Seattle, where the three cheapest cities are Stockholm, Copenhagen and Oslo and the fourth-cheapest is $105 behind. Two West Coast gateways, opposite cheap ends.

The reason is not mysterious. Southern Europe from the Bay Area is a long flight whichever way you cut it, so the routing advantage that makes Seattle–Stockholm cheap does not exist, and the fares end up being set by competition and connecting capacity rather than by geometry. Iberia, TAP and the Gulf carriers all sell one-stop itineraries into Iberia and the Mediterranean from SFO, and they price against each other.

Where San Francisco is genuinely well placed

Three cities put SFO in the national top three:

• Vienna, $627 — 3rd of 26, behind only New York at $580.
• Naples, $633 — 3rd of 26, behind Chicago at $579.
• Edinburgh, $674 — 3rd of 26, and the one city where San Francisco beats New York, by $9.

That last one is worth pausing on. Across all 40 European cities we price, San Francisco is cheaper than New York on exactly one, and the margin is $9. New York's median advantage over SFO is $98.

Where it is badly placed

Helsinki is the worst result on the board: $815 from San Francisco against $541 from New York, a $274 gap — the widest of any city from this airport. Stockholm is the same story in miniature at $617 against Seattle's $418.

The Nordics are simply not San Francisco's market. If Scandinavia is the trip, the honest answer is that a positioning flight to Seattle changes the arithmetic more than any booking tactic will, and the Nordic discount explains why those fares behave the way they do.

At the expensive end, the Greek islands are brutal from everywhere and worse from here: Santorini $917, Mykonos $972. Both are more than $280 above SFO's median.

Los Angeles is a coin flip

Los Angeles runs a $666 median against San Francisco's $671. That is a $5 difference across 40 cities, collected on the same day — comfortably inside the noise of a single collection, and not a reason to drive anywhere.

The medians hide real divergence on individual routes, though. Check both airports for the city you actually want rather than assuming either is your gateway, and see cheap flights from Los Angeles for how that gateway's own cheap end is shaped.

How to use this airport

• Pick the Mediterranean city you actually want. From SFO the cheap end is flat, so preference costs nothing. This is the rare gateway where "wherever is cheapest" is bad advice.
• Do not fly to Scandinavia from here without checking Seattle. The gap on Stockholm is $199 and on Helsinki $274.
• Check Los Angeles in parallel, not because it is cheaper on median but because individual routes diverge.
• Treat $611 as the floor and $671 as normal. Anything under $600 to a major European city from SFO is a genuinely good fare.

What flexibility is worth here, and it is not much

The single most repeated piece of cheap-flight advice is to be flexible about your destination. Across our whole grid that advice is sound: the gap between the cheapest and dearest European arrival city is $348 on the national median.

From San Francisco it collapses. The spread across the ten cheapest cities is $22, and even stretching to the fifteen cheapest only reaches into the $650s. A traveler who genuinely does not care where they land saves less from this airport than from any other major gateway we price.

The corollary is more useful than it sounds: at SFO, flexibility about the date is worth far more than flexibility about the city. The seasonal swing on any single route here is several hundred dollars, against $22 for switching countries. Spend your flexibility on the calendar.

When to go

• Late October to mid-December — the best combination of low fares and reasonable weather in southern Europe, where the shoulder runs late.
• January to early March — as cheap or cheaper, and Andalusia and Malta stay mild while northern Europe does not.
• The fortnight around Christmas and New Year — a sharp spike worth avoiding unless the dates are the point.
• Late April to May, and September — the shoulders, and the best value once weather enters the calculation. September into the Mediterranean is the strongest single window from this airport.
• June to August — roughly double. No tactic closes that gap, and southern Europe in August is the worst value on this page.

Method, and its limits

Every fare was collected on August 30, 2026 from Google Flights, priced as a one-week round trip in economy for one adult, taking the cheapest available week in the following six months. Rankings use the median across all 40 cities, never the minimum: a minimum is a fact about one route on one day.

What this does not measure. Baggage is excluded, and most headline fares are the cheapest bucket, increasingly basic economy with no full-size carry-on. We have not yet priced carrier-level fares out of San Francisco; on the gateways where we have, the spread between the cheapest and dearest airline on a single route runs from $171 to $1,025 in economy.

This grid is refreshed monthly, in one sitting, and stamped with its date.

Where to go from here

• The cheapest places to fly in Europe ranks all 40 destinations with every gateway priced against them.
• Cheap flights from Los Angeles — the other California gateway, $5 apart on median.
• Cheap flights from Seattle — the West Coast airport with the opposite cheap end.
• Flexible on where you go? — what that flexibility is actually worth, airport by airport. San Francisco is where it is worth least.
• Barcelona and Madrid have their own pages with all 26 US gateways priced against them.
