Practical tips
Just like ferries, island flights fill up in July and August. Booking ahead gives you more choice of departure times and helps you avoid being stuck on Kos when you need to be in Thessaloniki.
By flying, you avoid the Piraeus, Rafina or Lavrio dilemma entirely. You go straight from Kos airport to Thessaloniki, with no ferry port to choose and no risk of heading to the wrong harbour.
Strong meltemi winds can cancel high-speed catamarans, but flights are generally more reliable. Still, keep some flexibility in your schedule if a tight onward connection or a prepaid hotel depends on this leg.
Domestic fares often include only a small cabin bag. If you travel with a backpack or a suitcase, check what is included before booking so you are not surprised by extra fees at the airport.
Kos airport is outside the main town, so allow time to reach it. Arrange a taxi or bus in advance, especially if you stay in a beach resort, and arrive early in the busy summer season.
The journey experience
Getting from Kos to Thessaloniki is a long way on a map, and on a Greek island-hopping trip it is exactly the kind of leg where the answer is simple: fly. The Dodecanese and northern Greece are far apart, ferry timetables change with the season, and many island links only run a few days a week, so a sea-and-land route quickly becomes a puzzle of connections.
The option available for this route is the domestic flight. It is the straightforward choice for independent travellers without a car: you check in at a small island airport, skip the port-hunting and the worry about which harbour a boat leaves from, and arrive in Thessaloniki ready to explore the city. A flight is also far less exposed to the strong winds that can delay or cancel crossings, which makes it reassuring if you have an onward booking in the north. Compare the duration and price shown in the table on this page to see how it fits your plan.
My advice: book your seat in advance for summer, when island flights fill up as quickly as ferries do, and keep your baggage allowance in mind. Check the departure time against your hotel check-out so you are not rushing. With one clear leg and no changes of port or island to manage, you can plan this transfer with confidence.

With a third day, add the Ladadika district for dinner, the Modiano and Kapani markets, and the Vergina royal tombs.
