Free WiFi at Athens Airport
Athens Airport offers free, unlimited WiFi 24 hours a day across the entire terminal. Connect to the “ATH Free Wi-Fi” network, open your browser, and tap “Connect to the Internet” on the portal page that appears. Access runs in 60-minute sessions — when one ends, simply reconnect for free, as many times as you need. It is enough for messaging, maps, and booking your ride into the city.
Stuck on the login page? Go to your phone’s WiFi settings, choose “Forget” for the ATH network, then reconnect — this clears most sign-in glitches. Charging points and USB sockets are available throughout the gates and seating areas if your battery is low after the flight.
ATMs at Athens Airport: Where to Get Cash
ATMs are plentiful and available 24/7. You will find machines from the major Greek banks — Alpha Bank, National Bank of Greece, Eurobank and Piraeus Bank — in both the arrivals and departures areas. The arrivals-hall machines are the most convenient: withdraw what you need on your way to the taxi rank or transfer meeting point.
Save money — two rules: First, use a bank-branded ATM and avoid the standalone yellow “Euronet” machines, which tend to charge higher fees and give poorer rates. Second, when any ATM offers to “convert” the amount to your home currency (dynamic currency conversion), always decline and choose to be charged in euros — your own bank’s exchange rate will almost always be better.
Currency Exchange at Athens Airport
Currency exchange at ATH is handled by ONExchange, open 24/7, with desks at the baggage-reclaim area (after customs) and on the departures floor. They buy and sell more than 60 currencies, so it is a reliable fallback if you arrive without any euros.
That said, airport exchange desks rarely offer the best rates. If you have a debit card with low foreign-transaction fees, withdrawing euros directly from a bank ATM is usually cheaper than exchanging cash — so use the exchange desk only for what you need to get going.
Cash or Card in Athens? How Much to Carry
Greece is largely card-friendly — cards, Apple Pay and Google Pay are accepted in hotels, restaurants, shops and most taxis. Still, it is worth carrying €50–100 in cash for small kiosks (periptera), bakeries, tips, and the occasional cash-only taverna. You do not need to load up at the airport: ATMs are on practically every corner in central Athens, so withdraw a modest amount on arrival and top up in the city if needed.
Mobile Data: eSIM vs Airport WiFi
Free airport WiFi is fine for landing tasks, but it does not follow you out of the terminal. For seamless data from the moment you step off the plane — maps, ride-hailing, translation — an eSIM you activate before you land is the easiest solution. See our Athens Airport eSIM & SIM card guide for the best-value plans and how to set one up in minutes.
Getting from Athens Airport to the City
Once you are online and cash-ready, the last step is getting into Athens. After a long or late flight, the easiest option is a fixed-price private transfer that meets you in the arrivals hall and tracks your flight, so there is no haggling and no surprise fares. For every option and current prices, see our Athens airport taxi guide, or read our Athens airport arrivals guide for a step-by-step of the arrivals process.
