Istanbul Airport (IST) vs Sabiha Gokcen (SAW)
Istanbul Airport (IST): The main international hub on the European side of Istanbul, 40 km northwest of the city centre. Most Athens flights use this airport. Metro Line M11 connects the airport to Gayrettepe station (35 min, 76 TL) and onward via Line M2. Taxis cost approximately 600-800 TL to central Istanbul (Sultanahmet, Taksim).
Sabiha Gokcen (SAW): On the Asian side of Istanbul, 50 km from the European city centre. Pegasus Airlines and some Aegean routes use SAW. Requires either a long taxi ride (90-120 min across the Bosphorus, 800-1,200 TL) or bus (E10 Havas bus to Kadikoy, then ferry to European side). Only choose SAW if the fare saving is significant and you are staying near the Asian side of Istanbul.
Getting from Athens Airport to the City
Metro Line 3 (Blue): 10 euros, 40-50 minutes to Syntagma Square (city centre). The most convenient option. Runs every 30 minutes, 6:30 AM to 11:30 PM. A 5-trip metro ticket saves money if continuing to use public transport in Athens.
Express Bus X95: 6.20 euros, 60-90 minutes to Syntagma Square. Runs 24/7 -- the only option for very early/late arrivals. Slower than the metro but direct to Syntagma.
Taxi: Fixed rate 42 euros daytime (5 AM-midnight) or 55 euros overnight to central Athens. No haggling needed -- the fixed airport-city taxi rate is official. Journey time 30-50 minutes.
Grab/Uber equivalent (Beat): Around 30-40 euros from the airport. Beat is Greece's main ride-hailing app. Available from Athens airport.
Booking Tips
Book 40 days ahead: Trip.com and Skyscanner data both identify approximately 40 days in advance as the optimal booking window for this route.

Sunday bookings: 6-13% cheaper than Friday purchases per ARC airline data.

Top Things to Do in Athens
Acropolis and Parthenon: Athens' defining landmark -- the 2,500-year-old temple complex perched on a limestone hill above the city. Admission 20 euros (reduced to 10 euros November-March and Sunday mornings year-round). Go early morning (8 AM when it opens) or late afternoon to avoid the midday heat and crowds. The combined Acropolis ticket also covers 6 other archaeological sites including the Ancient Agora.
Acropolis Museum: A world-class modern museum at the foot of the Acropolis hill, housing original sculptures and friezes from the Parthenon. Open Tuesday-Sunday. Admission 10 euros. Glass floors reveal ancient ruins beneath the building.
Plaka District: The oldest neighbourhood in Athens -- neoclassical houses, tavernas, and traditional shops on winding streets beneath the Acropolis. Best explored in the evening when the restaurants come alive. Try moussaka, souvlaki, and baklava at the traditional tavernas along Adrianou Street.
National Archaeological Museum: One of the world's great archaeology museums, housing the finest collection of ancient Greek art and artefacts. Admission 15 euros (free November-March Sundays). Allow a full morning.
Monastiraki Flea Market: Athens' famous Sunday flea market around Monastiraki Square -- antiques, vintage finds, street food, and a lively atmosphere. Best from 8-11 AM before the heat and crowds build.
Cape Sounion Day Trip: Take a KTEL bus (2.5 hours, 7 euros each way) from Athens to the Temple of Poseidon at Cape Sounion -- one of ancient Greece's most dramatically located temples, on a cliff above the Aegean Sea. Sunset from here is extraordinary.

Turkish citizens require a Schengen visa to enter Greece (which is an EU/Schengen Area country). Apply through the Greek embassy or consulate in Turkey well in advance. EU citizens do not need a visa. UK, USA, Canadian, and Australian citizens can enter Greece visa-free for up to 90 days within a 180-day period under Schengen Area rules (note the ETIAS pre-authorisation system being introduced for non-EU travellers in 2026 -- check etiasvisa.com for current status).
November and January are consistently the cheapest months. May and August are the most expensive. For visiting Athens, April-June and September-October offer the best weather (warm but not oppressively hot, fewer crowds than peak summer). Avoid mid-July to mid-August for both price and comfort -- Athens in August is very hot (36-40 degrees C) and extremely crowded.
