On longer Sardinian bus trips, a normal suitcase is usually manageable, but do not assume every regional bus has a coach-style luggage hold. ARST, the island’s main regional operator, allows two pieces free on extra-urban routes within its stated size and weight limits; larger cases can go in a luggage compartment only when the vehicle has one and the driver approves. That is the key reality with luggage on Sardinia buses: the vehicle and available space matter as much as the written allowance.
ARST’s official baggage allowance on extra-urban buses
For ARST’s servizi autobus extraurbani, the current Carta della Mobilità says a ticketed passenger may carry two pieces free of charge, subject to dimensions of 50 x 30 x 25 cm and a 20 kg weight limit. Bags must be placed in the available storage areas, such as the overhead rack or under a seat, without blocking the aisle, doors or seats.
The size limit is smaller than many airline cabin suitcases. A typical wheeled carry-on can therefore be technically oversized even if you think of it as “hand luggage.” Do not use an airline baggage label as your guide. Measure the case itself if you are trying to stay within the free ARST allowance.
ARST also states that a bag exceeding the size or weight limit must not go in the overhead rack. With the driver’s approval it may be placed in the bagagliaio, meaning the luggage compartment, if the bus has one. A third bag can also be accepted when space and load capacity allow, but it is chargeable. On an extra-urban service, the current rule prices that extra or oversized piece at the fare for a single tratta 2 ticket. Here tratta means a fare band, not “bus route 2.”
The big catch: a long route does not guarantee a luggage hold
Sardinia’s regional buses are public transport vehicles, not all long-distance touring coaches. Some departures use vehicles with an underfloor or side luggage bay; others may have only interior racks and floor-level passenger space. ARST’s own wording is deliberately conditional: oversized luggage may be placed in the hold where present.
This matters most when you travel with a full-size suitcase. A route that takes an hour or two on the timetable can still be operated by a bus without a useful external compartment. If there is no suitable place for the bag, or the bus is crowded, ARST may refuse to carry it. Having a valid passenger ticket does not guarantee that an oversized case can be accommodated.
How boarding works when you have a suitcase
- Be at the correct stop before the bus arrives. Regional stops are not always staffed stations. At a roadside fermata, you may have only the driver to ask.
- Do not drag a large case straight into the passenger area. If it will not fit safely under a seat or in the rack, ask first: “Dove metto la valigia?” means “Where do I put the suitcase?”
- Ask about the luggage bay. “Posso mettere la valigia nel bagagliaio?” means “Can I put the suitcase in the luggage compartment?” If the side compartment is closed, wait for the driver’s instruction rather than trying to open it yourself.
- Keep essentials with you. Passport, wallet, phone, medicines, keys and electronics belong in a small personal bag at your seat, not in a compartment you cannot access during the ride.
- Validate your ticket. Loading a suitcase does not remove the normal ticket rules. ARST requires tickets to be validated at the start of the journey; electronic tickets bought through supported apps must also be activated according to the app procedure and shown when required.
If you are boarding at a busy autostazione, watch the destination display and bay information carefully. “Extraurbano” is the useful word for regional buses. Partenze means departures, arrivi arrivals, while stallo or corsia may identify a bus stand or lane. Coincidenza means a connection.
Tell the driver when your bag is in the hold
On a route with intermediate stops, the driver may not know that you need something retrieved from the luggage compartment. Before your stop, make your intention clear. “Scendo a Nuoro e ho una valigia nel bagagliaio” means “I’m getting off in Nuoro and I have a suitcase in the luggage compartment.” Substitute your own destination.
At a small roadside stop, do not walk away from the bus until you have your case. If other passengers are also unloading bags, check the tag, color and handle before taking one. ARST places baggage under the passenger’s responsibility and says it is not responsible for theft, loss, deterioration or tampering, so a simple name tag and phone number are worthwhile.
Transfers are where luggage causes the most trouble
A connection that looks tidy on a journey planner can feel much tighter when you have to wait for a luggage bay to be opened, retrieve a case, find the next stand and load again. Do not assume an onward bus will wait because your first service is late. This is especially important when changing between operators or making the last useful connection of the day.
If your trip uses several buses, check the operator as well as the times. The regional Around Sardinia system can plan journeys and sell tickets for several participating public transport companies. For the rest of your route, you can also organize your Sardinia itinerary so that hotel changes, bus legs and backup options are not packed into one fragile chain.
Be more conservative when the next leg is a flight, ferry or final bus of the evening. A smaller backpack may be worth more than the extra clothes if it removes the risk of an oversized case being refused.
Other Sardinian bus operators can have different rules
ARST is the main reference for regional public buses, but it is not the only company you may encounter. Do not assume its allowance automatically applies to an airport coach or private regional service.
For example, the Sun Lines 2026 direct Line 90 between Olbia, Sassari and Alghero states that the ticket includes one standard suitcase and one small carry-on item, with an additional bag charged at €5. Bulky or sports luggage is charged separately. Deplano, which operates routes including Nuoro to Olbia Airport, states on its current route information that accompanying baggage is carried free but remains under the passenger’s care and supervision.
These differences are why the operator name on your itinerary matters. If your ticket or timetable does not say ARST, open that company’s baggage conditions before travel. Airport and seasonal services in particular may have their own specific rules.
What to do if the driver says your suitcase cannot travel
If a large bag is refused because there is no luggage bay, no safe interior space or the bus is too full, arguing about how long the route is will not solve the problem. ARST’s conditions explicitly allow refusal when baggage cannot be safely accommodated.
- Ask about the next departure: “C’è un altro autobus?” means “Is there another bus?” A later vehicle may be different, although there is no guarantee it will have more luggage space.
- Check the same journey with another operator: this is most realistic on airport and major intercity corridors, not in every village.
- Use a taxi for the fragile leg: if missing the bus would also mean missing a ferry or flight, protecting the major connection is usually more important than saving the local fare.
- Avoid this problem before it starts: if your whole trip is bus-based, one medium soft-sided bag is easier to place than a rigid large spinner.
The worst time to discover the problem is at the last departure from a small town. If you must travel with a large rigid suitcase, build important travel days around earlier services so there is still a recovery option.
Lost bag or something left on the bus
If you leave an item behind, contact ARST promptly with the date, approximate time, line, boarding point and destination. Its current service charter says found objects are registered and kept by the relevant territorial office for two months. It lists 351 837 4226, also available on WhatsApp, and informazioni@arst.sardegna.it for lost-property enquiries.
If a suitcase was in an external compartment, include a precise description: brand, size, color, distinctive straps or stickers, and anything attached to the handle. Keep your passenger ticket or digital receipt until the bag is back with you because it helps establish which service you used.
Pack for the bus network, not just the flight
Travelers moving around Sardinia without a car often focus on airport baggage limits and forget the smaller spaces on regional transport. The island is much easier with luggage when you can lift your own bag, carry it across a bus station, fit it under or near a seat when necessary, and move quickly during a change.
If your trip includes several towns, consider a compact suitcase or travel backpack plus one small day bag. Soft bags have an advantage because they can compress into awkward racks and compartments. Keep liquids tightly sealed, and do not plan to transport fragile or valuable items in the external hold. ARST’s conditions also prohibit dangerous, flammable and corrosive materials, as well as certain fragile or valuable items and containers such as wine or oil.
Sardinia can work without a car, but the route needs more discipline than a rail-heavy mainland itinerary. If you are still deciding whether public transport suits the trip you want, the practical comparison in our Sicily vs Sardinia guide explains why the island’s bus network works best when you choose fewer bases and avoid overloading transfer days.
