About A3
Aegean Airlines — operating under the IATA code A3 — is Greece's flag-carrying legacy carrier, the kind of airline that takes its national identity seriously without being precious about it. Based at Athens International (ATH), it runs a network of 370 non-stop routes touching 119 airports, which is a serious operation for a country whose geography demands it. Greece has islands. Lots of them. And Aegean has built its business around connecting them, along with reaching the European cities where the Greek diaspora actually lives. The network spans a cumulative 475,190 kilometres, with the longest single hop stretching to Dubai (DXB) at 3,272 kilometres.
Why fly A3?
The honest case for Aegean comes down to this: if you're flying into or around Greece, they simply know the terrain better than anyone else. With 228 routes operating within Greece alone, they're not supplementing domestic travel — they are domestic travel. From ATH, 109 routes fan outward, covering both mainland connections and island-hopping logistics that would otherwise take a ferry and a full day. Beyond Greece, their European reach hits the cities Greeks actually travel to — Germany gets 19 routes, Italy 14, France 13. The service reputation is genuinely strong for a legacy carrier of this size, and the Miles+Bonus loyalty programme is worth enrolling in even for a single trip if you're a Star Alliance frequent flyer.

Tips for booking A3
Book directly through Aegean if you're combining a main hub like ATH with onward domestic legs — the fare bundles tend to protect you better if connections are disrupted. The SKG hub in Thessaloniki is underrated for travellers entering from northern Europe; you'll sometimes find less congested connections there than through Athens. Check your fare class carefully before assuming lounge access or checked baggage is included — economy tickets on shorter hops can be stripped down. If you're a Star Alliance Gold member, reciprocal benefits apply. And for island routes operating out of RHO or HER, book early in spring: summer capacity fills faster than most travellers expect.
