Night train vs. flying: the real cost of an overnight journey

The pitch for night trains writes itself: skip the airport, skip the hotel, wake up in the centre of a new city. It’s a genuinely good deal on plenty of routes. It is not automatically true on every route, and pretending otherwise does readers no favours. Here’s the honest comparison, using real routes and prices.

The real cost of flying overnight distances

A flight fare is rarely the full story. Add two airport transfers (rarely under €15–20 each way once you’re outside a city centre), check-in and security buffers that mean a “90-minute flight” is really a half-day commitment door to door, and — if your flight lands too late or leaves too early to make it worth going to bed — a hotel night on either end. A night-train sleeper fare, by contrast, bundles transport and a bed into one price and gets you there while you’d otherwise be sleeping anyway.

Case 1: Vienna–Rome — the train wins on convenience

ÖBB Nightjet covers this in about 14 hours, city-centre station to city-centre station, with a sleeper from around €80 and a private ensuite Comfort Plus cabin from €130. A low-cost flight can be cheaper on paper, but factor in transfers at both ends and you’re often looking at four to five hours door to door, plus you still need a hotel room in Rome or Vienna if your flight doesn’t align neatly with your day. Once you count the bed the train fare already includes, the comparison narrows sharply or flips outright.

Case 2: Paris–Nice — the train wins on price

SNCF’s Intercités de Nuit does this route daily in about 11h 44m, with couchette berths from just €29 — genuinely one of the cheapest overnight sleeper fares anywhere in Europe. Flights from Paris to Nice can occasionally match that fare on a good day, but only before you add the RER or taxi to Charles de Gaulle or Orly, security queues, and the transfer from Nice airport into town. For budget travellers, this is close to a no-contest win for the train.

Case 3: Stockholm–Narvik — where flying genuinely wins

This is where honesty matters. At 19h 30m over 1,456 km, Stockholm–Narvik is one of the longest night trains in Europe, with sleeper fares from around €110. It’s a spectacular ride across the Arctic Circle, and reduced 2026 frequency has made berths harder to get. But a flight covering the same distance takes a fraction of the time, and if your goal is simply to reach Swedish Lapland as fast as possible, flying wins outright on time. People choose the train here for the journey itself — the scenery, the midnight sun or northern lights — not because it’s the faster or cheaper option. That’s a legitimate reason to pick it, but it’s a different reason than the one that applies to Vienna–Rome or Paris–Nice.

Carbon

Rail travel in Europe generally produces a small fraction of the per-passenger emissions of flying, largely because most of the continent’s mainline network runs on electricity rather than jet fuel. It’s a real advantage of the train option, though exact figures vary by country’s grid mix and aircraft type, so treat any specific multiplier you see quoted elsewhere with some scepticism.

When flying genuinely wins

• Very long distances where the train journey stretches past 15–18 hours, like Stockholm–Narvik
• Genuinely rock-bottom promotional flight fares that undercut even a budget couchette
• Trips where the travel day itself is dead time you want minimised, not part of the experience

When the night train wins

• Medium distances of roughly 8–15 hours, where flight-plus-transfers-plus-hotel adds up to close to or more than the train fare
• City-centre to city-centre routes that avoid a remote airport entirely, like Paris Austerlitz to Nice-Ville
• Trips where arriving rested and getting a full extra day matters more than shaving off a few hours

The honest bottom line

Don’t default to “the train always wins” — it doesn’t, and Stockholm–Narvik proves it. Do the door-to-door maths for your specific route, including a hotel night if your flight times demand one, before assuming either option is obviously cheaper or faster. On plenty of medium-distance European routes, the night train quietly wins that comparison once you count everything a flight actually costs.
