Athens International Airport terminal guide for first-time visitors
For a first visit, Athens Airport is easier to understand when you treat it as one main terminal building with a separate satellite gate section connected by an underground passage. Most passenger activity stays in the Main Terminal. Passengers who land pass through Level 0 when leaving the airport. A big number of those who can also be found in this area are the ones who are about to take a flight. If, however, their boarding gate location is C15-C40 range then the passengers will be processed through the Satellite Terminal.
Majority of the time, fresh travelers end up wasting their time at three main points: right after their arrival, while going from check-in to security, and during the walk to a satellite gate. That is why a useful terminal guide should focus on movement, not labels. Travelers need to know where passport control is, where bags arrive, where check-in starts, where security begins, and walking time. Before flying, it helps to review the layout of athens international airport terminals. A quick look can save time and reduce wrong turns.
Athens terminal layout for first-time visitors
Think of Athens Airport as two linked sections. The Main Terminal includes all the areas of arrivals, baggage claim, check-in, plus the majority of the departure gates. The Satellite Terminal which caters to gates C15-C40 can be reached from the Main Terminal via an underground passage. After check-in, find the signs near counter 70, then take the escalator or elevator down. The walk with the help of moving walkways covers approximately 15 minutes.
| Area | What it is used for | What first-timers should remember |
| Main Terminal | Arrivals, baggage claim, check-in, many departure gates | This is where every arriving passenger exits |
| Satellite Terminal | Departure gates C15-C40 | Reach it through the underground link from the Main Terminal |

Terminal guide for arrivals
The arrival process at Athens Airport is pretty simple. Just keep your eyes on the ‘Arrivals’ signs, if you have come from a country outside the Schengen area then after showing your passport you can go straight to the baggage reclaim area where you will be able to find your belt on the monitors. After customs, all arriving passengers enter the public arrivals hall on Level 0 of the Main Terminal. The exit area depends on where the flight came from. Non-Schengen passengers leave through Area A, between Exits 1 and 2. Schengen passengers leave through Area B, located between Exits 4 and 5.
Passport control and baggage claim
In the case of non-Schengen arrivals, the Hellenic Police conduct the passport control. The airport mentions that there are two flows: that of EU passport holders or ID holders and that of non-EU passport holders. The e-passport gates in the Main Terminal can be used by biometric passport holders meeting the conditions. It might shave off a couple minutes from your time, but it would definitely be more convenient at the control point if you had your passport and landing papers ready beforehand.
A practical first-timer sequence looks like this:
- Follow Arrivals signs after leaving the aircraft.
- Complete passport control if your flight arrived from outside Schengen.
- Check the monitor for your baggage claim belt.
- Clear customs and step into the public arrivals area.
- Decide on your next move before stopping: taxi rank, pickup point, train, or bus.
Taxi rank and information points
The airport’s taxi rank is easy to miss if you exit on autopilot. The official site of Athens Airport confirms that taxis are available 24/7 at the designated taxi waiting area at Exit 3 of the Arrivals Level. The airport information counter is also next to Exit 3, and there is another information counter on the Departures level between Entrances 2 and 3. For someone arriving tired, that clustering matters: Exit 3 is the useful anchor point for both taxis and live help.
| Need after landing | Best place to aim for |
| Taxi rank | Exit 3, Arrivals Level |
| Live airport help | Information counter next to Exit 3 |
| Someone picking you up | Public arrivals area after customs |

Athens International Airport terminal guide for departures
In the case of departures at the Athens Airport, online check-in is typically the most efficient choice in case the airline provides it. Most airlines check-in online up to 30 days or 4 hours prior to departure, and some can charge to print a boarding pass at the airport in case it was not done in advance. Cabin baggage only travelers frequently can go directly to security and passport control with the boarding pass saved or printed. Even passengers who have baggage to carry must go to a counter or bag-drop point.
Another area that is a time-waster to the traveler is move from check-In to the gate. Check-In Hall is found on the Level 1 of the Main Terminal on the Departures Level. Once you have checked in, you are better to proceed to the security checkpoints without any delay particularly at the busy times when there might be an unforeseen increase in the length of queues.
When the boarding pass sends you to a satellite gate
If your boarding pass shows gates C15-C40, do not treat that as a small detour. Official guidance says those gates are in the Satellite Terminal and the underground moving-walkway route takes about 15 minutes. That means a passenger who reaches security “on time” for a main-building gate may feel late for a satellite gate. My working rule for first-timers is simple: add at least 20 extra minutes when your gate is in the satellite building. That is a practical buffer, not an airport rule, based on the official walking time plus the chance of gate changes and control queues.
Athens International Airport terminal guide for connecting flights
Athens is relatively straightforward with boarding pass and baggage tag sorted. The airport supplements that you should check the flight information monitors when you have the boarding pass to the next flight and in order to reach the right gate you should follow the terminal signs. The Main Terminal consists of A1- A27 and B1-B31 and the Satellite Terminal consists of C15-C40. The airport sends you to the closest transfer desk, self-service unit or Check-In Hall on Departures Level 1 in case you do not have the boarding pass.
The baggage side is where first-time visitors make wrong assumptions. The airport says transfer bags are usually checked through to the final destination, but there are cases where passengers flying onward to regional Greek airports may still need to pick up bags and clear customs at Athens. That is why the baggage tag matters more than estimation. Read the tag before you walk away from the desk.
Common connection mistakes:
- Looking only at the airline app and skipping the airport flight monitors.
- Assuming every onward gate is in the Main Terminal.
- Forgetting that passport control may still be part of the connection for non-Schengen travel.
- Assuming the bag will transfer automatically without checking the tag.
First-time visitor checklist for Athens Airport
Should you have to pass border control while traveling, definitely the most crucial thing is to always have your passport at hand for inspection. If you find yourself at a taxi stand or airport information counter, think of Exit 3 at the Arrivals Level to be your point of reference. In case your gate number is within the range of C15 to C40, you should also think about the fact that your walking time will be longer.
Besides, if you are not sure, the airport operates information counters 24 hours a day on both Arrivals and Departures. There are also additional help points in the terminal areas.
