Luggage in Europe 2026: Train, Bus and Plane — the Real Rules

Short answer: in Europe, luggage doesn't follow a single rule but three opposing logics. On trains, there is virtually no weight limit: SNCF, ÖBB, DB, Trenitalia and Renfe accept your bags free of charge, the only constraints being the number of pieces (generally two large bags + one accessory) and being able to carry them on your own. On coaches, the model is mixed: Flixbus and BlaBlaCar Bus include one hold bag up to 20 kg plus one carry-on, and charge €5 to €12 for extras booked in advance — far more at the roadside. On low-cost flights, luggage is the product: only a small under-seat bag is included with Ryanair, Wizz Air, Transavia or easyJet, and everything else is paid for — from €6 to €60 depending on how early you book, with a penalty that often exceeds €70 at the gate. The golden rule for 2026: your train/bus/plane decision should never be based on the seat price alone, but on the price of seat + actual luggage, calculated before you click.

It's the most ordinary and most expensive scene in European travel: a boarding queue at Beauvais or Bergamo, a yellow metal sizer, and an agent asking you to place your bag inside. It's three centimetres too big. The ticket cost €19. The surcharge will cost €75.

Luggage has become the economic adjustment variable of passenger transport. Understanding its rules, mode by mode, often saves more than every promo code combined. Here's the state of play, without the received wisdom.

The train: Europe's most permissive mode

No European rail operator weighs your bags. That's the structural fact, and it explains why the train remains unbeatable for trips involving bulky gear — camera equipment, instruments, long stays, partial moves.

The real rules in 2026:

Two nuances matter. First, Ouigo introduced a stricter allowance than TGV Inoui several years ago: one carry-on plus one large bag included, with a second large suitcase theoretically chargeable. In practice, platform checks do exist and are occasionally enforced. Second, Eurostar is the European exception: the border crossing requires airline-style check-in, and a maximum of two suitcases per adult, genuinely verified.

So the train's real problem isn't weight but space. On a packed TGV on a Friday evening, the overhead racks fill up in ten minutes and the end vestibules overflow. A large hard-shell bag then becomes a nuisance for everyone. In that context, a soft-sided cabin suitcase with wheels slips in where a rigid shell gets stuck, and lifts effortlessly into the high racks — an underrated advantage when travelling alone.

Night trains call for specific logistics

With more than forty active lines across Europe in 2026, the night train has changed travel habits. But an ÖBB Nightjet or European Sleeper couchette cabin offers only a few dozen cubic centimetres of secure storage: the large bag goes under the lower bunk or in the rack by the compartment door.

Three habits are essential:

• keep your passport, phone, wallet and medication on you overnight, in a pouch worn under your clothes;
• use a small TSA padlock on the zip of the large bag left in the shared rack;
• prepare a separate overnight bag (toothbrush, change of clothes, earplugs) so you don't have to open the suitcase at 11 pm in a narrow corridor.

The new Nightjet capsules rolled out by ÖBB have an individual lockable compartment, but that isn't yet the standard across the European fleet.

The coach: the hold allowance, the forgotten asset of cheap travel

This is where much of the value-for-money case for long-distance buses is decided, and where the comparison with low-cost flying becomes brutal.

Flixbus, Europe's leading operator, includes in the ticket price:

• one carry-on bag (roughly 42 × 30 × 18 cm, 7 kg);
• one hold bag of 80 × 50 × 30 cm, up to 20 kg.

BlaBlaCar Bus follows a similar logic: one cabin bag plus one hold bag included, with modest surcharges for additional pieces. Alsa and the Spanish or Portuguese operators are in the same ballpark.

An extra bag booked online costs around €5 to €12. Paid at boarding, if there's still room in the hold, the price rises sharply — and the driver can simply refuse the item if the hold is full.

Two blind spots to know about:

1. Special luggage. Skis, surfboards, bulky instruments and non-folding bikes fall into a separate, chargeable category (often €9 to €15) and above all require advance booking, since the number of slots per departure is limited. Turning up without a reservation means risking being left behind.
2. Labelling. Bus holds get emptied haphazardly at every intermediate stop. A standard black suitcase with no distinguishing mark is the classic recipe for confusion at Lyon Perrache or Munich ZOB. A brightly coloured luggage tag with your name and phone number clearly legible costs two euros and eliminates the problem.

Finally, ridesharing falls entirely outside these rules: there's no official allowance, only the driver's boot. Best practice is to flag a large bag in the booking message, not at the car door. A driver in a three-door city car is entitled to refuse a 90-litre suitcase, and they will.

Low-cost flying: luggage IS the business model

In 2026, the €15 seat still exists. It includes nothing more than a bag the size of a small backpack, slipped under the seat in front of you.

The usual "free" size limits:

The key point isn't the headline price but its curve. A cabin bag added at the time of booking typically costs €6 to €25; added 24 hours before the flight, it doubles; presented at the boarding gate without having been paid for, it commonly costs between €45 and €75, sometimes more on high-demand routes. The airline isn't selling a service, it's selling a penalty for poor planning.

Three practical consequences:

• Check the dimensions to the centimetre. The metal sizers are strictly enforced, wheels and handles included. A 40x20x25 cabin backpack built exactly to the free-bag format settles the question once and for all for weekend trips.
• A pocket digital luggage scale avoids nasty surprises at the bag-drop desk on the way home, when the suitcase has picked up two kilos of souvenirs.
• The liquids rule in the cabin remains, at most European airports, containers of 100 ml maximum in a one-litre transparent bag. The rollout of C3 scanners, which was supposed to lift this limit, was partly suspended then re-authorised at certain equipped airports: the regime is not consistent from one airport to another. Until harmonisation is complete, treat the 100 ml rule as the default standard.

The calculation that changes the decision: seat + luggage

This is where multimodal comparison really comes into its own. Take a Paris–Milan one-way trip with a 15 kg suitcase.

The ranking flips as soon as luggage is factored in: the low-cost flight that looked half the price becomes equivalent, or even more expensive — and that's before counting the transfer to a secondary airport. This is exactly why a multimodal comparison site should be read with the baggage surcharge in mind.

Add a time variable: trains and buses don't require early check-in. An hour and a half early at the airport plus forty minutes of shuttle adds up to more than two hours that appear nowhere on the price sheet.

Seven rules to never pay a surcharge again

1. Measure your bag at home, wheels and handle included, and note the three dimensions in your phone. That's the figure you'll compare at every booking.
2. Buy the luggage allowance when you book, never afterwards. The gap between the initial price and the last-minute price is the most profitable trade-off there is.
3. Wear the heavy stuff. Shoes, coat, camera: what's on your body is never weighed. A 35-litre travel backpack stays under most airlines' cabin thresholds while swallowing the equivalent of a small suitcase.
4. Compress. Vacuum compression bags or simple packing cubes save 20 to 30% of volume, which is often enough to go from hold format to cabin format.
5. Book special luggage in advance (bike, skis, instrument): the constraint isn't the price, it's the number of slots.
6. Photograph your suitcase before departure, and keep the check-in tag. If it's lost or delayed, that's the item that speeds everything up.
7. Label the inside as much as the outside. A sheet with your contact details tucked inside the suitcase survives a handle being torn off.

What if your luggage is lost or damaged?

The legal regimes differ by mode, and that difference is little known.

• Plane: the Montreal Convention applies. The carrier's liability for loss, delay or damage is capped at 1,288 SDR per passenger (about €1,500). A claim must be filed within 7 days for damage and 21 days for delayed delivery.
• Train: European Regulation (EU) 2021/782 on rail passengers' rights refers, for registered luggage, to the CIV uniform rules. But the vast majority of rail luggage is not registered: it stays in your care, and the carrier is only liable if fault is proven. In other words: on trains, luggage freedom comes at the price of full personal responsibility.
• Coach: Regulation (EU) No 181/2011 governs the rights of long-distance bus passengers, with compensation provided for luggage lost or damaged in an accident, within the limits set by national law.

In every case, your travel insurance or the cover provided by certain bank cards often protects your luggage better than the carrier itself. Check before you leave, not after.

Key takeaways

Luggage is the last cost item you discover too late. It completely reshuffles the ranking of transport modes: trains and buses include it, low-cost airlines sell it at a premium and punish improvisation harshly.

The method fits in one sentence: decide on your luggage before deciding on your transport. If you're heading off for a weekend with a bag that fits under the seat, low-cost flying is often unbeatable. As soon as you're carrying a real suitcase, a bike, equipment or gifts, trains and coaches regain the advantage — no stress, no sizer, and none of that dreaded sentence at boarding: "could you put it in the frame, please."

Before you book: always compare ticket price + luggage + transfer to the departure point. That's the only total that counts.
