For decades, the classic air travel route between the Greek islands was marked by a crucial bottleneck: almost all domestic flights had to stop over in Athens or Thessaloniki.
If you wanted to travel from Mykonos to Santorini, you would spend hours layovers at Athens airport, or face port chaos and the usual unreliability of the ferries. However, a significant change is underway in commercial aviation in the Aegean Sea for the 2026 season: Direct routes are opening that eliminate layovers, revolutionizing the way tourists travel between the islands by air.
Direct connections between the Aegean Islands
The main new feature for 2026 is the new direct connection between Syros and Heraklion, Crete. This Aegean Airlines flight, with two weekly frequencies (Mondays and Fridays), directly connects the capital of the Cyclades with Greece’s largest island, significantly reducing travel time that previously required a stopover in Athens or a long ferry journey.
Furthermore, Heraklion is increasingly establishing itself as a major connecting hub in the southern Aegean Sea. For the 2026 season, airlines will operate the following routes:
- Heraklion (Crete) to Santorini: Several daily direct flights.
- Heraklion to Mykonos: At least one daily direct flight.
- Heraklion to Rhodes: Daily direct connections between the two largest islands in the south.
Island Hop-On Hop-Off
Beyond these connections between major cities, there are also direct routes with multiple stops.
Sky Express operates an essential “air bus” service (the “Agonas” line) that travels around the Dodecanese archipelago. This allows travelers to fly directly between Rhodes, Kos, Kalymnos, Leros, and Astypalaia without having to return to a major airport.
Olympic Air does the same, connecting Sitia (Crete) with Kasos and Karpathos, ending its route in Rhodes.
Is flying the best option?
While direct flights save a lot of travel time, they aren’t always the best option. If flights aren’t purchased on sale, the cost of flying between islands is almost always higher than the ferry. There are also certain baggage restrictions, as these routes are typically operated with turboprop aircraft (ATR-42/72, Dash 8/Q400), which have stricter weight limits for carry-on and/or checked baggage than international flights.
Seasonal availability is a critical factor, as these direct routes virtually disappear from November to March (outside of the tourist season). By 2026, air travel between the Aegean islands will offer unprecedented convenience for those who prioritize speed. However, it is essential to book these direct flights at least three to four months in advance, as the capacity of these smaller aircraft fills up quickly.
While the ferry remains the quintessential romantic element of travel to Greece, Greek airlines are finally offering a direct and viable alternative for those traveling between islands.
