AMTS city buses cost 1.40 euros for 90 minutes and 3.50 euros for a day pass, but on board those rise to 2 and 4.10 euros: buy in advance. From the airport the Alibus costs 4 euros, on board too (4.60 if the ticket is bought on other buses), is valid 90 minutes on other city lines too and reaches the central station. The Circumetnea metro charges 1 euro a single ride, 1.40 for a 120-minute ticket and 3 euros for a day pass; the 2-euro MetroBus ticket covers metro and bus together for 120 minutes. Trains for Syracuse, Taormina and Messina leave from the central station, coaches for Palermo and Agrigento from the Via Archimede terminal. From the airport (Catania Fontanarossa, CTA, about 4 km from Piazza Duomo as the crow flies): the cheapest and fastest way is the train from Catania Aeroporto Fontanarossa station to Catania Centrale, €2.20 and about 8 minutes; AMTS's Alibus reaches the central station in about 15 minutes and costs €4, valid 90 minutes on the other city lines too. Watch out: the Alibus ticket is sold at the airport machines or in the AMTS app.
- Buy your ticket before boarding: on board it costs 40 per cent more, and travelling without one carries a fine equal to sixty times the price of the 90-minute ticket.
- For Etna in a day without a car there is the AST bus from Piazza Papa Giovanni XXIII to Rifugio Sapienza, with very few departures: check the times with the operator.
- The 2-euro MetroBus pays off as soon as you make more than one journey: it covers metro and bus for two hours and costs the same as two single tickets.
- The airport is four kilometres from the centre: a taxi takes minutes, but without the meter running the ride becomes a negotiation. The Alibus leaves from outside arrivals.
