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

Short answer: in 2026, there is still no single baggage rule that applies to every mode of transport in Europe. The train remains the most generous (bags are, in practice, neither weighed nor measured by most operators), the long-distance coach imposes a strict allowance (generally 1 hold bag + 1 piece of hand luggage), and the low-cost plane is the only place where a wrongly sized bag can cost up to €70 at the boarding gate. The golden rule: size your bag around the most restrictive link in your itinerary — almost always the flight.

A Paris–Lisbon journey in three legs — TGV to Hendaye, coach to Porto, low-cost flight back — can cost less than €90 in transport… and €60 more if the suitcase wasn't chosen with the air segment in mind. That's the blind spot of multimodal travel: we compare ticket prices, never baggage policies. Here, mode by mode, is the real state of the rules as this autumn 2026 begins, and what Brussels has in store to harmonise it all.

The train: Europe's most permissive mode

This is rail's great, little-known advantage. On virtually every European network, no bag is weighed or charged for, which partly explains why heavily loaded travellers — families, sports gear, long stays — are coming back to the train.

What the conditions of carriage actually say

• SNCF (TGV Inoui, Ouigo, Intercités): the general terms allow up to two bags + one accessory per traveller, with an indicative size limit. Since the awareness campaign launched in 2024, every bag must be identified with a name tag — an obligation that is rarely enforced, but which can lead to a fixed penalty.
• Deutsche Bahn (ICE, IC): unlimited hand luggage "subject to available space", a very flexible principle that makes the German network the favourite of heavily loaded Interrail travellers.
• Trenitalia and Italo: a comparable policy, with dedicated luggage areas at each end of the train on the Frecciarossa.
• Eurostar: this is the notable exception. Two bags of 85 cm maximum per dimension + one piece of hand luggage, with genuine checks at check-in, since the service includes airport-style security screening.
• Renfe (AVE, Avlo): three items, 25 kg in total in theory. Here too, checks are rare, except on Avlo where staff pay closer attention.

The real limiting factor, then, isn't the written rule but the physical space on board. On double-deck Ouigo TGVs, the luggage areas fill up from the middle of the train onwards. A 55 cm cabin trolley case fits everywhere, including in the overhead racks; a 70 cm suitcase often ends up standing in the vestibule, at the risk of blocking the aisle.

On night trains — Nightjet, European Sleeper, or the new services counted by Le nouvel Économiste (41 lines in Europe in 2026) — the constraint is reversed: it isn't weight that causes problems, but bulk in a 4- to 6-berth compartment. A large hard-shell suitcase quickly becomes unmanageable there; a soft bag slides under the bunk.

Items that cause trouble

Bikes, musical instruments and surfboards fall under specific rules:

• Assembled bike: reservation compulsory and chargeable on most equipped TGVs (around €10), free on many TER services and German or Austrian regional trains with a bike supplement.
• Dismantled bike in a bag: accepted as ordinary luggage if it fits in a reasonably sized cover. This is the trick most used on Interrail, and it justifies buying a foldable bike transport bag that packs away into your rucksack on arrival.
• Animals: a ticket or supplement everywhere, with wide variations (around €7 on SNCF for a small animal in a carrier, free under certain conditions in Germany).

The long-distance coach: a strict but clear allowance

The coach is the mode where the rules are the most explicit and the most enforced, because the hold is physically limited.

Three things travellers find out too late:

1. An extra bag isn't guaranteed. If the hold is full, it can be refused even if paid for. On very busy routes in August (Paris–Barcelona, Berlin–Prague), it happens.
2. Weight is sometimes checked during loading on international routes, particularly at non-Schengen border crossings.
3. Nothing protects your belongings in the hold. Unlike on a plane, there is no tracking tag or tracing system. Slipping a Bluetooth luggage tracker into your case has become second nature for many night-coach regulars.

The low-cost flight: the only segment where a mistake costs cash

This is where most of the budget is decided. Since "basic" fares became widespread, free cabin baggage has shrunk to a personal item that must fit under the seat.

The dimensions to remember in 2026

• Ryanair: 40 × 25 × 20 cm under-seat bag included in all fares. 10 kg cabin bag (55 × 40 × 20 cm) chargeable, unless you take the Priority option.
• easyJet: small under-seat bag included; large cabin bag reserved for higher fares or passengers who have bought the option.
• Wizz Air: small bag included, "WIZZ Priority" cabin bag chargeable.
• Vueling, Transavia: similar logic, with dimensions that are close but not identical.

A few centimetres' difference is enough to trigger a surcharge. At the boarding gate, the fees to regularise the situation frequently exceed €60 to €70 per bag — often more than the ticket itself.

Two habits dramatically cut the risk:

• Measure before you leave, handles and wheels included. Airport sizers don't forgive 2 cm too many.
• Weigh at home. An electronic travel luggage scale costs about the price of a coffee and saves you the queue at the re-tagging desk.

What the European Parliament is preparing

The issue has become political. In 2025, the European Parliament adopted a position supporting free carriage of a reasonable piece of hand luggage (generally cited at around 7 kg and a standard cabin format) as part of the revision of the air passenger rights regulation, following on from the case law of the Court of Justice of the European Union, which has held since 2014 that hand luggage of a reasonable weight and size cannot be charged for separately.

In Spain, the consumer authority had already penalised several airlines in 2024 for this practice, with fines totalling several tens of millions of euros. The airlines are contesting it, the European trilogue continues: as of 19 August 2026, nothing is yet applicable in a uniform way. In other words, keep paying attention to dimensions; don't count on regulation to save you this autumn.

Ridesharing: the unwritten rule

No regulation, no allowance, no official dimensions: on BlaBlaCar, luggage is a matter of negotiation with the driver. It's at once the most flexible and the most uncertain mode.

Good practices that prevent a refusal at the meeting point:

• Declare your luggage when booking, in the confirmation message, stating the real format ("a 60 L hiking rucksack", not "a small bag").
• Favour a soft bag rather than a hard-shell suitcase: a city car's boot fills very differently with one or the other.
• On long journeys, a foldable waterproof travel bag lets you compress the volume and wedge it between two hard cases.
• Check what the profile says: many drivers explicitly state "large luggage accepted" or "limited boot space".

Packing for a multimodal itinerary

The logic is simple: the most restrictive mode sets the rule for the whole trip.

The hierarchy of constraints

1. Low-cost flight → the strictest dimensions (55 × 40 × 20 cm at most, often less).
2. Long-distance coach → weight (20 kg in the hold, 7 kg in the cabin).
3. Eurostar / trains with security screening → 85 cm per dimension.
4. Ordinary train → practical bulk only.
5. Ridesharing → volume and flexibility.

If your itinerary includes even a single low-cost flight, size everything around that leg. A 55 × 40 × 20 cm bag will get through absolutely anywhere else in Europe.

Three trade-offs that save weight

• Liquids. On fully overland journeys, there are no checks: you can take your usual bottles. As soon as a flight is involved, the 100 ml rule in a transparent bag applies — even though new 3D scanners allow liquids and electronics to stay in your bag at some European airports. That roll-out remains uneven from one airport to another: assume the strict rule applies.
• Electronics. A power bank must travel in the cabin, never in the hold — a rule harmonised by the aviation authorities, with a capacity ceiling (100 Wh without authorisation). A compact universal travel adapter usefully replaces three separate chargers.
• Clothes. On a trip of more than ten days, two laundry loads at a hostel weigh less than five extra outfits.

The mistakes that cost the most

Key takeaways

In 2026, the train remains the most comfortable mode of transport for anyone travelling loaded: no weighing, no charges, no queue at the bag drop. The coach imposes a clear but rigid allowance. The low-cost plane, for its part, has turned baggage into a loss-leader — and that is precisely where the gap widens between the advertised price and the price paid.

Until the revision of the European passenger rights regulation is finalised, the only protection is preparation: a single format, measured, weighed, valid across the whole chain. Comparing modes on Gopaxo only makes sense if you also compare what they charge for once the ticket is bought.
