Airport hub guide
Athens International ATH: the complete layover guide
One Main Terminal, a Satellite annex down an underground walkway, a clean Schengen split, and a fair reputation for overnight sleeping. Here is how to work a layover in Athens.
Layover verdict Good across the board. The airport runs 24 hours, staff tolerate sleepers, the lounge spread covers both sides of the passport divide, and the city is a 40 minute metro ride away.
Best lounge play The Goldair Handling lounges take Priority Pass, and since late March 2026 both main terminal locations run 24 hours, the Schengen lounge opposite Gate B13 and the non Schengen lounge in Hall A, a rare round the clock setup in Europe.
The one thing to know Your gate letter decides your world. A gates are non Schengen, B gates are Schengen and domestic, C gates sit in the Satellite Terminal. Crossing between A and B means passport control.

Orientation
How Athens airport is laid out
Athens International, officially Eleftherios Venizelos, is refreshingly simple after a megahub: one Main Terminal handles almost everything, and a Satellite Terminal connected by an underground walkway absorbs the overflow.
The Main Terminal stacks three levels: arrivals on the ground floor, departures above, a food court on top. Airside, departures splits in two. Hall A serves non Schengen flights from gates A1 to A23. Hall B serves Schengen and domestic Greek flights from gates B1 to B31. Passport control enforces the split, so an A gate boarding pass locks you out of the B side lounges, and the reverse holds too.
The Satellite Terminal carries the C gates, C15 to C40, and serves both Schengen and non Schengen traffic across its ten jet bridges. You reach it through an underground corridor fitted with moving walkways. Budget 10 to 13 minutes on foot. No bus, no train, just a long well lit tunnel, which beats a tarmac bus in summer heat.
Connections are straightforward by European standards. Staying within the Schengen B and C gate world means no passport check, just a walk. Crossing between Schengen and non Schengen means a passport queue, and Athens gets slammed in peak summer, so do not treat a tight connection in July like one in February. Minimum connection times vary by airline, so check your booking.
Getting to the city is one of this airport's quiet strengths. Metro Line 3 runs from the station opposite the terminal to Syntagma Square in about 40 minutes, every 30 minutes, 10 euros one way. The suburban railway leaves from the same station toward Larissis, the main rail hub, in about 44 minutes. The X95 express bus is the budget play at 5.50 euros, running 24 hours to Syntagma, every 15 to 20 minutes by day and 30 to 40 at night. Take the metro out and keep the X95 for the hours when the metro sleeps.
Terminal by terminal
What each area gives you
Main Terminal, Hall A (non Schengen)
This is where long haul and other non Schengen departures live, gates A1 to A23. The Aegean lounge on this side sits on the third floor before the non Schengen square and keeps long hours, from 5 am to 1 am. Goldair Handling runs lounge space in the Hall A departure area that takes Priority Pass and has kept 24 hour doors since late March 2026. Hall A also hides the most useful amenity at ATH: pay showers near Gate A10, around 10 euros, typically accessible 24 hours. After a red eye, that shower beats any lounge buffet.
Main Terminal, Hall B (Schengen and domestic)
Gates B1 to B31 handle Schengen and Greek domestic traffic, the busiest stretch of the airport in island season. The lounge bench here is genuinely deep for a Schengen pier. The Goldair Handling lounge opposite Gate B13 runs 24 hours and takes Priority Pass. The Skyserv Melina Mercouri lounge across from Gate B11 also takes Priority Pass and opens 6 am to 10 pm. Lufthansa keeps a Business Lounge near Gate B12, open 4:30 am to 10 pm, for its premium and status passengers. If you hold Priority Pass and the Goldair lounge is rammed, walk two gates and try Skyserv.
The Satellite Terminal
The C gates, C15 to C40, sit at the end of the walkway on two levels, one for arrivals and one for departures. It is the newest part of the airport and the calmest place to wait. Aegean operates a lounge near Gate C34 on level 2, and Goldair Handling runs a lounge in the Satellite Terminal that appears in the Priority Pass network. Do not linger in the Main Terminal until final call when your flight leaves from a C gate; the tunnel walk eats those minutes fast.

FAQ
Athens layover questions
Can I sleep overnight at Athens airport?
Yes, and ATH is one of the friendlier European airports for it. The airport operates 24 hours and staff generally leave sleepers alone, though there are no official rest zones and parts of the Schengen Hall B area may close between roughly 1 and 4 am. If you want a real bed, the Sofitel Athens Airport sits directly opposite the arrivals level.
Is wifi free at Athens airport?
Yes. Connect to the ATH Free WiFi network for free access in 120 minute sessions, and when a session expires you can simply reconnect at no charge. Charging points are available in the Schengen, non Schengen and Satellite gate areas.
Can I leave the airport during a layover at ATH?
If you have the right to enter the Schengen Area, yes, and Metro Line 3 puts you in central Athens in about 40 minutes. Entry depends on your nationality and Schengen visa rules, and arriving from a non Schengen country means clearing passport control both ways; verify before travel.
Is 6 hours enough to see the Acropolis from Athens airport?
Yes, if everything cooperates. The metro takes about 40 minutes each way, which leaves roughly 3 hours for the Acropolis after you allow for security and boarding on your return. Book your ticket in advance, travel hand luggage only, and abort the plan if your inbound lands late.
How do I get from Athens airport to the city center?
Metro Line 3 runs to Syntagma Square in about 40 minutes for 10 euros, with trains every 30 minutes, and the suburban railway reaches Larissis station in about 44 minutes. The X95 express bus costs 5.50 euros, runs 24 hours a day to Syntagma, and leaves every 15 to 20 minutes during the day.
Which lounges at ATH take Priority Pass?
The Goldair Handling lounges are the core of the Priority Pass network here, including the lounge opposite Gate B13 in the Schengen area and the Hall A non Schengen lounge, both running 24 hours since late March 2026, plus one in the Satellite Terminal. The Skyserv Melina Mercouri lounge across from Gate B11 also takes Priority Pass, open 6 am to 10 pm.
