Athens International Airport "Eleftherios Venizelos"

For Hall A long-hauls in summer, plan 2.5–3 hours before departure; Schengen/domestic often needs less but still protect a buffer for bag drop.

Official average security is short, but travelers routinely report 45–60 minutes combined security/passport on busy US/long-haul banks, and VAT refunds can add another hour.

Schengen = Hall B; non-Schengen = Hall A after passport control—wrong hall means no lounge and a wasted walk.

Satellite gates need the underground link (~10–15 min with bags); Non-Schengen passengers can shop Schengen after showing a boarding pass, but not the reverse.

Hit Eat Greek (Schengen platea) or Ergon (non-Schengen) for real gyros/Greek plates before you settle for Starbucks.

Gregory’s for pies/salads, Lukumades at Bistrot Attica for loukoumades, and Kostarelos deli for last-minute Greek dairy if you want edible souvenirs.

Expect knock-on delays in peak season—37% of 2025 departures ran >15 minutes late, with June/July the worst months.

Reactionary and airport-of-departure restrictions dominate reasons; leave tight island connections with checked bags only if you accept real miss risk.
