The board flipped in 2015

I · What the board actually lists

A departures board lists doors, and the doors go by other names than the cities

An airport is the one place in a city where people's intentions are posted in public, one under another, in order of departure time. The board says nothing about who boards or why, but it says where, and read year after year, set beside the boards of every other airport in the country, it answers a question no official form asks: where do the people of one particular corner of Romania actually go?

The first surprise is in the names. Europe's big cities are all there, of course, except that above them, right at the top of the list, sit places most passengers could not find on a map. Luton is a town north of London, in Bedfordshire, with 225,300 residents at the 2021 census. In 2024, 1,886,522 passengers moved through it in one direction or the other on Romanian routes, 2.1 times what Heathrow, Gatwick and Stansted managed between them, which came to 902,850.

The second name on the list is Bergamo, a Lombard city of 122,077 people, which took 1,295,510 passengers, more than Rome's two airports combined. Third is Munich. Only in fourth place does a Romanian city appear: Bucharest, with 814,765 passengers on domestic routes. And the two small towns at the head of the list, Luton and Bergamo, add up to more between them than every route between Romania and Germany.

A departures board shows you where the plane sets you down, and that turns out to look very little like a map of important places.

II · The year it flipped

Until 2014, the name at the top was always a large city

In 2001, Romania's busiest air link ran to Tel Aviv, with 173,215 passengers. First place then moved for a few years between Amsterdam, Paris and Vienna, and from 2009 Munich held it for six years running. All of them are cities a schoolchild could point to, and all of them have airports built to represent the country they sit in.

In 2015 the order broke. Luton climbed to first place with 908,290 passengers and stayed there for ten years running, including the two years when flying nearly stopped altogether. By 2019 it had reached 1,810,679, and by 2024, 1,886,522. Since then, the country's air board has been led by a place nobody chooses for its own sake.

The growth behind this reversal is enormous and unevenly spread. Between 2005 and 2024, traffic at Romanian airports rose 7.3-fold, from 3,008,364 passengers to 22,022,106. Of everything flown in 2024, 65.8% went to destinations that appeared on no Romanian board at all in 2005.

III · The door, not the city

In every country in western Europe, the side door beats the front gate

The pattern repeats from one border to the next with a consistency that quickly stops looking like coincidence. In France, the airport at Beauvais — a Picard town of almost 56,000 people some eighty kilometres north of Paris — took 1.9 times as many Romanian passengers as Charles de Gaulle. In Belgium, Charleroi took 6.4 times as many as Brussels Zaventem. In Germany, Memmingen, an Allgäu town of fewer than 45,000 people, took 3.4 times as many as Berlin. Even in London, where all four airports serve the same city, Luton alone takes 67.6% of all traffic with Romania.

The immediate explanation is called a landing fee. Secondary airports charge airlines far less than the big ones, and the cheap carriers build their networks on exactly that gap. What is more interesting is what it says about the passenger that this arithmetic wins, year after year. Someone flying to a meeting in Paris does not get off at Beauvais, because they would lose an hour and pay for a coach. Someone flying to work, or home from it, does the sum differently. The board does not say who is who, but it does say that on the French route the side door is chosen almost twice as often as the front gate.

IV · Every airport has its own Europe

Sibiu flies to Germany, Târgu Mureș flies to Budapest

If price were the whole story, the country's ten boards would look alike. They look strikingly different instead, and the differences track things we already knew without ever having seen them counted.

At Sibiu, 63.4% of 2024 traffic was with Germany: Munich, Memmingen, Nuremberg, Karlsruhe, Dortmund. At Târgu Mureș, a board with four routes sends 52.8% of its passengers to Budapest. At Bacău and Craiova, Italy takes over 43% of everything. At Suceava, where the board has seven lines, Luton alone swallows 39.8% of the whole year. At Oradea, more than half the traffic leaves for Bucharest, which makes that board very nearly a domestic one.

Otopeni behaves unlike all of them. Its 13.9 million passengers spread across 65 routes, and the busiest of those, to Bergamo, does not reach 4% of the total. It is the only airport in the country that looks international in the ordinary sense of the word, meaning one that does not lean on a handful of destinations.

The rest lean. Of the ten airports with traffic in 2024, nine have Luton among their top three destinations, and at Iași, Suceava, Bacău and Craiova it comes first. The only exception is Oradea, which has no Luton route at all.

Set two boards side by side in the tool above, Sibiu and Bacău for instance, and the difference shows up in the first three lines.

V · What the board does not show

A board counts flights, and people are not flights

Someone who leaves in March and returns in August appears twice; someone who commutes monthly appears twenty-four times a year. On the same plane to Bergamo, on the same day, sit a person going to work, a person going home to their parents and a person going to see the city, and the figures do not tell them apart. All that can be said with certainty is that this journey is made very often, and that it is made through the cheap door.

One large part of the same story is missing from the board altogether: the coaches and the private cars that carry people to Italy, Germany and Spain without touching an airport. The board shows only the part that flies, which is the part that can be counted exactly.

VI · How the figures were worked out

Airport pairs, year by year, from 2001 to 2024

The figures on this page are the ones Romania reports to the statistical office of the European Union: for every pair made up of a Romanian airport and a partner airport, the number of passengers carried in a year, both directions together. A passenger counts once for each flight.

Routes between two Romanian airports appear in the returns of both, so in the national total they are counted once; on each airport's own board they stay where they are, because there they really do represent a destination. For a few years at the start of the period, some destinations appear under codes covering a whole region rather than a single airport; these are listed under the name of the city they refer to. The airports at Constanța, Arad, Satu Mare and Tulcea have no routes of their own in the table. The last complete year is 2024.

Every figure and every comparison in the text was recalculated from those returns before publication, including the ones that set a single airport against an entire country.
