I’ll be honest—when I started planning my three-month European adventure in early 2026, I was convinced budget airlines were the only way to go. Then I booked a €29 flight from Barcelona to Paris, spent €65 on baggage fees and airport transfers, and arrived at my hotel more exhausted than when I’d started. That’s when I decided to actually run the numbers on trains versus planes.
After traveling through 12 countries using both methods, I’ve got some insights that might surprise you. Spoiler: the “cheapest” option isn’t always what it seems.
The Real Cost Breakdown (With All the Hidden Fees)
Let me walk you through a real example from my trip. I needed to get from Amsterdam to Brussels—a route I’ve done both ways.
Flying: I found a Ryanair flight for €32 on Booking.com. Sounds great, right? But then came the reality check. Airport transfer from Amsterdam Centraal to Schiphol: €18. One checked bag: €35. Priority boarding because I didn’t want to risk losing my carry-on space: €12. Transfer from Brussels Charleroi Airport (which is actually 46km outside Brussels) to the city center: €22. Total: €119 and nearly 5 hours door-to-door.
Train: Thalys high-speed train direct from Amsterdam Centraal to Brussels Midi: €79 when I booked three weeks ahead. No baggage fees, no transfers, no security lines. Travel time: 1 hour 53 minutes station-to-station, and both stations are in the city center. Total: €79 and about 2.5 hours total.
The train cost €40 less and saved me 2.5 hours. This pattern repeated itself on most routes under 600km.
For longer distances, flying still wins on price—sometimes. My flight from Lisbon to Copenhagen cost me €187 all-in (including a checked bag booked through Booking.com), while the train journey would’ve required multiple connections over 40+ hours. In that case, the plane was the obvious choice.
Time: It’s Not Just About Flight Duration
Here’s what I learned the hard way: that “1 hour 15 minute flight” is misleading marketing.
For my Rome to Vienna trip, the flight itself was 1 hour 25 minutes. But I had to arrive 2 hours early for security, spent 30 minutes getting through baggage claim, and took a 45-minute bus from Vienna Airport to the city center. Door-to-door time: just over 5 hours.
The night train on the same route? I boarded at Roma Termini at 7:40 PM with a €89 sleeper cabin (booked through the ÖBB website), slept through the journey, and woke up at Wien Hauptbahnhof at 9:04 AM. I saved a hotel night (worth at least €70) and didn’t lose any sightseeing time.
My rule of thumb now: for journeys under 4-5 hours by train, trains usually win on total travel time. Paris to London (2h 15m), Barcelona to Madrid (2h 45m), Frankfurt to Paris (3h 50m)—all faster city-center to city-center by train.
Comfort and the Sanity Factor
Let’s talk about what your travel experience actually feels like, because this matters more than I expected.
On trains, I could stand up whenever I wanted, walk to the café car, work on my laptop with reliable wifi (most high-speed trains have it now), and actually enjoy the scenery rolling past. The seats are spacious—even in second class, I had more legroom than any economy flight I’ve taken. No middle seats, no armrest wars, no one reclining into my lap.
My favorite travel day was the train from Zurich to Milan through the Alps. I sat in the panoramic car with my coffee, watching snow-capped mountains pass by, and actually felt refreshed when I arrived. Compare that to my cramped Ryanair flight from Budapest to Brussels where I couldn’t even open my laptop.
Budget airlines have gotten even more restrictive in 2026. Many now charge €15-25 for any carry-on larger than a personal item. The seats seem to get smaller every year. And don’t get me started on the aggressive onboard sales pitches.
That said, flying has one major comfort advantage: speed on long distances. When I needed to get from Athens to Edinburgh, I wasn’t about to spend three days on trains. The 4-hour flight (plus airport time) was absolutely the right call.
Environmental Impact (If You Care About That)
I wasn’t planning to make this a major factor, but it’s hard to ignore. Trains in Europe produce roughly 80-90% less CO2 than the equivalent flight. After reading about this, I signed up for travel insurance through SafetyWing (which covers train travel comprehensively) and started defaulting to trains when the time difference was reasonable.
Does this matter for your trip? That’s personal. But if you’re trying to reduce your environmental impact without giving up travel, choosing trains for medium-distance trips is one of the easiest wins.
Booking Strategy: How to Get the Best Deals
Here’s what actually worked for me in 2026:
For flights: I found the best deals on Booking.com’s flight search, usually booking 6-8 weeks ahead for the best prices. Budget airlines are cheapest on Tuesdays and Wednesdays. Always calculate the true cost including bags and transfers before booking.
For trains: Book directly through national rail websites when possible—they’re often cheaper than third-party sites. For international routes, I used Trainline’s app which shows all options across different companies. Book 2-3 months ahead for the cheapest fares; prices increase as the date approaches. Many countries offer discount cards that pay for themselves after 2-3 trips.
For ground transfers: I used Discover Cars to rent vehicles for rural areas where neither trains nor flights made sense. For cities, I found that many train stations are central enough that I didn’t need transfers at all—huge time and money saver.
One hack I discovered: night trains often cost the same or less than day trains, and you save a hotel night. The €89 I spent on that Rome-Vienna sleeper cabin replaced a €70 hotel and a €60 day train ticket. Total savings: €41 plus I didn’t lose a travel day.
Bottom Line: Which Should You Choose?
After all this testing, here’s my framework:
Choose trains when: Your journey is under 600km, you’re traveling between major cities, you have checked luggage, you want to work or relax during travel, or the train journey is scenic.
Choose flights when: You’re covering 1,000km+, you’re going to/from remote destinations, time is extremely limited, or the price difference is more than €100 in favor of flying.
For everything in between, run the actual numbers including all fees and transfers. That €29 flight might really cost €110 and five hours of your day. That €79 train might be the better deal and get you there rested and ready to explore.
The biggest lesson from my three months bouncing around Europe? Flexible thinking wins. I’m no longer “team plane” or “team train.” I’m team “whatever makes the most sense for this specific trip.” Sometimes that’s a high-speed rail journey with Alpine views, sometimes it’s a budget flight across the continent. Both have their place in smart European travel.
