From Athens airport to Piraeus you have three real options: Metro Line 3, the X96 express bus, and a taxi. The right one is decided by the clock, by how much you are carrying, and by how long there is until your boat sails.
Two of the three go by road. The road is the only part of this journey whose length can double without warning, and the train is the only one of the three that a full city cannot slow down.
Every figure below names the body that publishes it. OASA, the Athens transport authority, for the buses, the tickets and the airport metro service. STASY for the Line 3 timetable. Athens International Airport for the taxi tariff. That matters more here than on most pages, because a large share of the pages answering this question are selling you a transfer. We are not selling anything.
The useful question is not which option is cheapest. It is which one still works when your flight lands late.
Fares, tickets and durations on this page were last checked in July 2026.
The three options, and what each one really costs you
The fare is the least interesting difference between these three. Compare them on what actually varies: whether traffic can lengthen the trip, how often the thing leaves, how far you drag your own bags, and whether it exists at three in the morning.
| Option | Roughly how long | Can traffic lengthen it | How often it goes | Luggage reality | Around the clock |
|---|---|---|---|---|---|
| Metro Line 3 | Runs to a timetable, and the road cannot change it | No | OASA publishes the airport service as every 30 minutes through Line 3, all week | You carry it. Platform, carriage, stairs, then the walk | It has a first and a last train. Get both from STASY for your date |
| X96 express bus | Approximately 90 minutes, which is OASA’s own measurement in normal conditions | Yes | OASA lists the airport express lines as a 24-hour service | Into the hold, then out on the waterfront | Yes, per OASA |
| Taxi | Quickest of the three in an empty city, no quicker than the bus in a full one | Yes | It leaves when you get in | Into the boot, to the gate | Yes, at a higher overnight tariff |

Now the mechanism that survives every price change, and it is the reason a family does the sum differently. The airport sits outside the standard fare zone. Per OASA’s own fares page, the ordinary 90-minute city ticket is not valid on the airport express buses, nor on the Line 3 section between Koropi and the airport. The airport has its own tickets, the metro one and the express-bus one are different products, and both are priced per person: 9.00 euros one way on the metro, 5.50 euros one way on the express bus, with a 16.00 euro metro return valid for 30 days.
Multiply that by four before you feel thrifty. A group crosses the line where one taxi is the cheaper object, and it crosses it sooner than most people expect.
The honest summary the table cannot give you: two of you with hand luggage and three hours until the boat, take the train. Four of you with four cases and ninety minutes, stop reading and take the taxi.
What the boats do once you reach them is a separate subject with its own guide to the ferry network. How we date and re-check the numbers above is set out in our editorial policy.
The metro cannot be stuck in traffic, and that is the whole argument for it
Metro Line 3 runs from Athens airport across the city to Piraeus. It is the only one of the three options that traffic cannot lengthen, which is what makes it the one you can plan a ferry around. It is also the least frequent of the three, and the least kind to heavy luggage.
Then there is the question every reader has, and we are going to give you the honest answer rather than a confident one.
We cannot tell you from a primary source whether your train runs the whole way without a change. STASY, the metro operator and the only body that publishes the Line 3 timetable, would not open for us. The sources that do publish an answer contradict each other: the official Athens city guide describes airport passengers changing at Doukissis Plakentias, while other accounts describe a through service that needs no change at all. One of them is out of date and we cannot tell which. We are not going to pick the flattering one and pass it off as fact.
What is true either way is also what you should do. Read the destination on the front of the train and on the platform board at the airport, because Line 3 trains do not all terminate at the same station. If yours turns back short of Piraeus, you change onto another Line 3 train: same line, same ticket, one platform. Plan for that and you are covered whichever way the timetable falls this season. Confirm it at STASY for your date.
The frequency is the real cost of this option. OASA states that the airport routes operate every 30 minutes through Line 3, throughout the week. That is a fraction of how often the rest of the metro runs, and it is the number to keep in your head, because miss one and you stand on a platform with your bags for exactly the half hour you were trying to save.
The cheapness is real. So is the price. A full carriage in July with your case between your knees, then Piraeus station, where the crowd around you is other people with ferry tickets and the same idea. Good with hand luggage, poor with two large cases and a tired child.
Lifts and escalators exist and they are not everywhere, and a step-free route through a busy interchange with luggage is not the journey the map shows. If that is your constraint, read travelling in Greece with limited mobility before you land. The rest of the country’s transport works differently again, and getting around Greece covers it.
The X96 is slow, and at three in the morning it is the thing that is moving
The X96 loses on speed and wins on availability. It is not a compromise between the train and the taxi. It is the answer to one specific question, and the question is what runs at four in the morning.
OASA publishes the useful facts about it, and they are good ones. The airport express lines operate on a 24-hour basis. The X96 connects the airport to the port of Piraeus along the coastal Posidonos avenue. And OASA’s own measurement puts the route at approximately 90 minutes. That figure is OASA’s word rather than ours, and it is a measurement in normal conditions: on the coast road, in August, at six in the evening, it is not a promise.
There is a rule on these lines that almost nobody repeats, and the operator publishes it plainly. On the airport express routes, disembarking is restricted on the way to the airport, and boarding is restricted on the way from it, and OASA states that these restrictions apply at all hours. If you were planning to join the X96 somewhere other than the airport, check at the stop rather than assume.
The ticket is the express-bus airport ticket, not the city ticket, and per OASA it covers one journey.
Two things make it suit ferry travellers specifically. It runs along the coast to the port itself rather than to a station beside it, so for some gates it puts you down closer than the train does. And your bags spend the journey in the hold instead of on your shoulders.
The warning is the one the table gives. It shares the road with everyone else. If the boat is tight, this is the wrong choice at five in the evening and the right one at five in the morning. And if the boat you are rushing for does not sail at all, that is a different problem with its own rules.
A taxi buys you a door, and it does not buy you the traffic
Athens International Airport publishes a flat taxi fare from the airport to the Athens city centre, with a daytime rate and a higher rate overnight, and the official Athens city guide states that it includes all applicable surcharges. What applies to Piraeus, which is not the city centre, we could not confirm at the airport or at any regulator.
So we are not printing the figure.
The airport’s own site would not open for us. The numbers in circulation come mostly from sites that sell taxi rides, and they do not even agree with each other about the overnight rate. A fare here has to be traceable to the body that sets it, and this one is not. Read the tariff at Athens International Airport before you fly and you will have today’s number rather than one of ours going stale.
We are also not going to tell you that no flat fare applies to Piraeus. Plenty of pages say exactly that, with confidence. None of them is the airport. We could not open the tariff, so we do not know, and manufacturing the absence is its own way of getting a reader overcharged.
The practice is right whatever the tariff says. Agree the basis of the fare before the bags go in the boot: the flat rate if one applies where you are going, the meter if it does not. Ask for the receipt. Greek market rules put a notice about your right to one inside the cab, in Greek and in English.
Then build the decision on the thing that outlives every tariff revision. A regulated flat fare is a cap on the price. It is not a cap on the journey. It protects you from the surcharge and does nothing whatever about the ring road at six in the evening. A taxi is the quickest way to Piraeus in an empty city and sits in the same queue as the bus in a full one, and nothing at the arrivals kerb tells you which city you have landed in.
When the taxi is simply right, we will say so without embarrassment: four people, or two big cases, or a child asleep, or a boat in ninety minutes, or three in the morning. Divide the fare by the number of people before you feel virtuous about the train, because the airport ticket is priced per head and the taxi is not. What a driver expects at the end is in tipping in Greece, and what the card machine will ask you is in money in Greece.
Piraeus is not a door, and the last part is on foot
Your transfer ends at Piraeus. Your ferry leaves from a gate, the gate number is printed on your ticket, and the gates are not all in the same place.
Piraeus is a working port along a long waterfront, not a building with an entrance. The metro station is not the gangway, and neither is the bus stop. How the port is laid out, which gate serves which island and who runs it belongs to our guide to the ferry network and its ports, which carries the map and the gates. We deliberately do not repeat its numbers here, because two pages on one site quoting the same distance from memory is how a site starts contradicting itself.
The instruction for this page is one line: find the gate on your ticket before you get into anything. A gate at one end of the port and a gate at the other are two different last miles with the same suitcase, and the transfer that is right for one is not automatically right for the other.
This is the taxi’s one structural advantage, and money cannot buy it back on the other two. A driver can be told a gate number. A train cannot.
And the honest part about time, which nobody selling you a ride will mention: the walk at the end is the leg nobody budgets for. You do it last, in the heat, carrying everything you own, when you are already behind. If you land with hours to spare rather than minutes, somewhere to leave the bags is worth more to you than a faster transfer.
Your boat may not sail from Piraeus at all
Check the port on your ticket before you book any transfer. Athens has three ferry ports, and two of them are not Piraeus.
Piraeus sits on the far side of the city from the airport. Rafina and Lavrio sit on the same side as the airport. That is a fact about geography rather than a detail, and for the islands those two ports serve it changes everything: crossing Athens at all would be the mistake you were about to make.
Which islands each port serves, and how far each one is from the airport, is in our ferry guide, which has the distances and has been checked against the operators. We are not restating them here.
KTEL, the intercity bus network, runs the coaches to Rafina and Lavrio, and the airport is served. We are not printing a route number, a fare or a frequency for them, because we did not read one at the operator, and an invented route number is exactly the kind of specific-sounding detail that puts a stranger on the wrong bus. Get those from KTEL.
A transfer to the wrong port is not a mistake you can undo in the time you have. And sometimes the answer is not a boat at all: some islands you can fly to directly.
On an island the taxi rank is small, and it does not grow in August
Land on Santorini, Mykonos, Rhodes or Crete and the same three shapes reappear, minus the train. A KTEL bus that goes when it goes and costs very little. A taxi rank outside the terminal. Or something you booked before you flew.
The rule worth carrying is about the fleet. An island’s taxis are licensed and finite, and the number of them does not go up because it is August. So a rank that is half empty in May has a queue in August, and an evening arrival at the peak of the season is the one case where pre-booking is arithmetic rather than laziness. We will not tell you how many taxis there are or how long the queue runs, because we do not know, and neither does anyone who quotes you a figure.
We name no transfer company and no app. They rebrand, change hands and close between seasons, and a page built on their names is wrong by August. Book the category rather than the brand, and get three things confirmed in writing: the meeting point, the price, and what happens if the flight lands late.
On many islands the airport bus is perfectly good, and on others it is thin enough that waiting for it costs you the evening. Which is which changes island by island and season by season, and we do not pretend to know it for all of them. The island’s own page and the bus operator answer that better than we can.
One strategy removes the problem completely. On an island where you were going to hire a car anyway , collect it at the airport and the transfer stops being a transfer. Doing that without the traps is a separate argument, and it is in renting a car in Greece.
Work backwards from the boat
One calculation decides this, and it does not start at the plane.
Take the boarding cut-off printed on your ferry ticket. Subtract the walk to your gate. Subtract the transfer at its slowest plausible length rather than its advertised one. Subtract the baggage hall. What is left is your margin.
If the margin comes out negative, the fix is not a faster taxi, because a taxi cannot overtake a traffic jam. The fix is an earlier flight, or a night in Athens.
Then the choice, in one line each. Heavy bags and a tight boat: take the taxi. Hand luggage and time to spare: take the train, because it is the only one the road cannot lengthen. Three in the morning: take the bus.
What to lock in before you leave home is in what to book ahead .

Common questions
How do I get from Athens airport to Piraeus?
Three ways. Metro Line 3 runs from the airport to Piraeus and is the only option traffic cannot lengthen. The X96 express bus runs around the clock to the port itself and takes longer. A taxi is the quickest when the roads are clear and no quicker than the bus when they are not. Choose by the clock and the luggage, not by the fare. OASA runs the buses, STASY runs the metro, and the airport publishes the taxi tariff.
Does the metro go directly from Athens airport to Piraeus?
Line 3 is one line and it connects the airport with Piraeus, but we will not tell you that your specific train runs the whole way, because STASY publishes that timetable, we could not open it, and the secondary sources contradict each other. Do this instead, which is correct either way: read the destination on the train and on the platform board, because Line 3 trains do not all terminate at the same station. If yours turns back early you change onto another Line 3 train on the same ticket.
How long does it take from Athens airport to Piraeus?
The train runs to a timetable and takes roughly the same time whatever the roads are doing. The bus and the taxi take as long as the road allows, and OASA’s own measurement for the X96 is approximately 90 minutes in normal conditions, which is a measurement rather than a guarantee. Then add the walk to your gate, which is the part nobody budgets for.
Is there a flat taxi fare from Athens airport to Piraeus?
Athens International Airport publishes a flat fare from the airport to the Athens city centre, day rate and higher night rate, and per the official Athens city guide it includes all applicable surcharges. Whether any flat fare covers Piraeus is something we could not confirm at the airport, so we state neither that one does nor that one does not. Read the tariff on the airport’s own site, agree the basis of the fare before the bags go in the boot, and ask for the receipt.
Can I get from Athens airport to Piraeus in the middle of the night?
Yes. OASA lists the airport express bus lines, the X96 among them, as operating on a 24-hour basis, and a taxi runs at any hour on a higher overnight tariff. The metro has a first train and a last train, and only STASY can tell you what they are for your date, so check that before you build a 3am plan around it. An early boat after a late landing is a bus problem or a taxi problem, and pretending otherwise is how people end up sleeping in a terminal.
How much time should I leave between my flight and my ferry?
No single number is honest here, because it depends on your gate, your season and your hour. Use the method instead: start at the boarding cut-off on your ferry ticket, subtract the walk to the gate, subtract the transfer at its slowest plausible length, subtract the baggage hall. If the margin comes out thin, the fix is an earlier flight or a night in Athens, not a faster taxi. Your operator’s ticket says when boarding closes, and our ferry guide explains how the boats work.
Do I need a special ticket for the airport?
Yes, and this is the mechanism that outlives the prices. Per OASA’s fare page, the standard 90-minute city ticket is not valid on the airport express buses, nor on the Line 3 section between Koropi and the airport. The airport has its own tickets, and the metro one and the express-bus one are different products. Both are priced per person, so a group should multiply before comparing with a single taxi. Check the current price at oasa.gr rather than here.
Should I book a private transfer in advance?
Sometimes, and you should know that most of the advice you will find on this decision is written by companies that sell the transfer. We sell nothing. Pre-booking genuinely earns its money in four cases: a night landing, four people with luggage, an island arrival in peak season where the taxi fleet is small and finite, or anyone for whom queueing with a small child is not an option. We recommend no company by name, because they rebrand and close between seasons. Confirm the meeting point, the price, and what happens if the flight is late.
