€1.30 bus fare beats the Alibus price if 3S passes your hotel
3S is a regular city bus that runs between Naples International Airport (Terminal 1) and parts of the city for a standard ANM ticket price of about €1.30, which is far cheaper than the Alibus flat fare. It only really makes sense if your hotel or apartment sits directly along its route and you’re okay with frequent stops, locals getting on and off, and no luggage-focused layout.
The 3S stop sits outside Terminal 1 on the arrivals side, roughly a 3–5 minute walk from the exit doors once you clear baggage claim. Look for the standard ANM bus stop signs, not the Alibus stand, and check the front display for “3S” before boarding. Buses run on a city schedule with gaps that can stretch beyond 20–30 minutes, especially off-peak, so build in extra time if you’re catching a specific train or tour.
A single ANM ticket for 3S generally costs about €1.30 if bought in advance at a tabacchi shop or newsstand inside or near Terminal 1, and the same ticket type also works on other ANM buses and metro within its time validity. You validate the ticket on board in the yellow machine, and inspectors do spot checks in Naples, so don’t skip that step to save a tiny amount.
3S runs as a normal urban bus, so you’ll share space with commuters, students, and shoppers, not just flyers with roller bags. Expect standing room at busy times, tight aisles that make two large checked suitcases awkward, and stop spacing that can add 15–25 minutes compared to a direct Alibus ride, even though the actual distance from the airport into central Naples is only about 6–7 km.
There’s no guaranteed luggage storage on 3S, only standard seat rows and a couple of open platforms near the doors, so big bags end up in the aisle and can annoy other riders when the bus fills up. Drivers focus on traffic and schedule, not curbside service, so you handle your own bags, step up quickly, and be ready to get off as the doors open at your stop.
If your hotel is right on the 3S line and you want to save cash, the play is simple: buy an ANM ticket in the terminal before exiting, confirm the 3S stop location on a current map, and screenshot the route so you’re not trying to rely on mobile data once the bus pulls away.
