Taking the metro, step by step
Cross the footbridge from arrivals, buy the special airport ticket (€9: standard 90-minute tickets are NOT valid from the airport), and ride line 3 toward the centre: Syntagma for Plaka and most hotels, Monastiraki for the old town. Trains every ~30–36 minutes, roughly 6am–11:30pm.
Arriving at night
The X95 bus is the night hero: every 15–30 minutes around the clock from outside arrivals to Syntagma Square. Taxis at the rank charge the regulated €55 flat fare between midnight and 5am: confirm “flat fare” before rolling and you cannot be cheated.
Tips & common mistakes
Validate bus tickets in the machine on board. The metro’s airport branch shares track with the suburban railway: just match the platform sign to “Athens”. Sunday-morning departures are sparse: check times for dawn flights. Politely refuse unlicensed drivers who approach inside the hall: the rank and the apps are the only games worth playing.
Which option to pick for your situation
The fares and times are only half the decision. The right choice depends on your group, your luggage, and your arrival time, so here is how the three options sort out in practice.
- Solo or couple, daytime arrival, staying near Syntagma or Monastiraki: take Metro Line 3. At around 9 euros and about 40 minutes it is the most predictable, immune to the traffic that can stretch the X95 toward 70 minutes, and it drops you in the historic center near most central hotels.
If you are watching every euro and not in a hurry, the X95 bus at about 5.50 euros is the cheapest route and runs 24 hours, which makes it the default for late or pre-dawn flights when the metro may not be running. The trade-off is comfort: it is a city bus with limited luggage space, so it suits light packers more than anyone hauling two large cases.
Families, anyone with heavy bags, or groups of three or four should default to a taxi. The fixed fare of around 40 euros by day and 55 euros at night is set for the whole car, so split across four people it often beats four metro tickets and removes the station changes and stairs that make public transport awkward with children or luggage. Hotels far from a metro stop, such as those in Plaka’s quieter lanes or up toward Lycabettus, also tip the math toward a taxi since you would otherwise add a walk or transfer at the end. Whichever you choose, confirm the flat fare with the driver before setting off and use only the official taxi rank outside arrivals.
