The European Cities Where Shopping Around Pays, and the Ones Where It Doesn't

Two European cities in our grid carry almost exactly the same typical fare from the US. Berlin's median across 26 US departure airports is $690 and Paris's is $690.

Now the part nobody publishes: Paris varies by twice as much as Berlin. The cheapest Paris fare any US airport paid was $459; the cheapest Berlin fare was $590. Same median, and on one of them your departure airport is worth $231 while on the other it is worth $100.

That property — dispersion — is what this page is about, and it decides whether any of the usual advice is worth following on your trip.

The cities where where-you-leave-from is worth the most

City	Typical fare	Best any airport paid	Spread	Share of the fare	Cheapest from
London	$771	$405	$366	47%	Orlando
Helsinki	$705	$388	$317	45%	Washington DC
Oslo	$638	$422	$216	34%	Boston
Reykjavik	$632	$422	$210	33%	New York
Paris	$690	$459	$231	33%	New York
Stockholm	$617	$418	$199	32%	Seattle
Malta	$748	$507	$241	32%	Boston
Copenhagen	$653	$448	$205	31%	Seattle
Rome	$669	$461	$208	31%	New York
Seville	$786	$539	$247	31%	Orlando

London is the most dispersed city in Europe, and by a distance: a $771 median against a $405 best, which is 47% of the typical fare. Helsinki is close behind at 45%.

That is not a statement about London being cheap. London ranks 29th of the 40 cities we price. It is a statement about London being inconsistent — the same trip, in the same week, costs wildly different amounts depending on which side of the country you start from, because a very large number of airlines sell it from a very uneven set of airports.

Notice which departure cities keep appearing in the last column. Orlando produced the cheapest London fare and the cheapest Seville fare in the entire grid. That is not because Orlando is a great transatlantic gateway on the median — it is 22nd of 26 — but because leisure routes are priced to fill, and a single aggressive fare from a leisure market can be the best in the country on a given day.

The cities where it buys you nothing

City	Typical fare	Best any airport paid	Spread	Share of the fare	Cheapest from
Santorini	$945	$818	$127	13%	Los Angeles
Krakow	$711	$618	$93	13%	Boston
Mykonos	$965	$826	$139	14%	Los Angeles
Berlin	$690	$590	$100	14%	Las Vegas
Lisbon	$694	$581	$113	16%	Boston
Prague	$691	$580	$111	16%	Boston
Belfast	$895	$741	$154	17%	Chicago
Salzburg	$802	$666	$136	17%	Los Angeles
Milan	$691	$571	$120	17%	New York
Bordeaux	$773	$629	$144	19%	Boston

Krakow varies by 13% and Berlin by 14%. On these routes the price is genuinely the price. Checking a second departure airport, driving to a bigger one, or paying for a positioning flight will not find you a materially better fare, because there is not a materially better fare to find.

And the two most striking entries are the expensive ones. Santorini at $945 and Mykonos at $965 are the two dearest arrivals in Europe, and both sit among the least variable at 13% and 14%. They are expensive from everywhere. That combination — high price, low dispersion — is the worst one for a shopper, and it is exactly the case where the answer is not a better fare but a different arrival city entirely: Athens is $764 and a ferry away.

What this actually tells you to do

The practical rule is short. Look up your destination's dispersion before you spend any time hunting.

Above about a third of the fare — London, Helsinki, Seville, Malta, Dubrovnik, Paris, Budapest, Oslo, Reykjavik — the departure airport is worth real money, and checking a second one is the single highest-value thing you can do. Our departure-city guides price all 26, and a positioning flight can pay for itself at these spreads.

Below about a fifth — Krakow, Berlin, Prague, Lisbon, Milan, Santorini, Salzburg, Venice, Mykonos, Zurich — book from where you live. The fare is what it is, and the hours you would spend comparing are worth more than the difference.

In between, check one alternative airport and stop. The Fare Deal Checker will tell you where a fare you have found sits against both the national picture and your own airport's, which is the faster version of the same question.

Why dispersion varies at all

Three mechanisms account for most of the table, and all three are visible elsewhere in our data.

How many airlines sell the city. A destination served by a dozen carriers from a dozen US airports has many independent prices, and independent prices spread out. One served by two carriers from three airports has three prices that mostly agree.

Whether it is a leisure market. Leisure routes get priced to fill, aggressively and unevenly, which is why Orlando appears at the top of the last column twice. Business-heavy city pairs are priced more consistently because the demand is more predictable.

Whether a low-premium connector reaches it. Our connecting-hub data shows Icelandair, TAP and SAS undercutting nonstops from the specific US airports they serve. A city those carriers reach has a cheap option from some airports and not others — which is dispersion by definition. It is the same finding as Minneapolis against Detroit: whether a cheap connector sells your city is a commercial decision, and it shows up as variance.

What we cannot tell you yet

Whether to wait. It is the most common question about fares and this page does not answer it, because the data cannot. Every observation here was collected in a single sitting — deliberately, so that no two fares in the grid are compared across different weeks, which is what makes the comparison between cities trustworthy in the first place.

The cost of that choice is that we hold a photograph rather than a film. Answering "will this fall?" honestly needs at least two archived snapshots of the same grid. We have one, taken August 30, 2026. The second is due at the end of September, and every month after that adds a frame. When there are enough, this page gets the column it is currently missing.

Until then, treat dispersion as a fact about geography rather than about timing, and treat anyone quoting a "book 47 days out" rule as someone who has not shown you their data.

Method

Forty European cities, each priced from all 26 US departure airports on August 30, 2026 — the cheapest one-week round trip in the following six months, collected in one sitting. "Typical" is the median across those airports and "best" is the lowest any of them paid. A city needs fares from at least 15 of the 26 airports to be ranked at all, so a thin market cannot produce a spectacular spread from three observations.

The share column is what the rankings use. In absolute dollars the widest spreads would mostly belong to the most expensive cities, which would make this page a restatement of the price ranking rather than a different finding.

Where to go next: the cheapest places to fly in Europe ranks all 40 by price rather than by variance, what flexibility is worth by airport asks the same question from the departure side, and the deals hub publishes the thresholds that decide what counts as a good fare in each city.
