Finding cheap flights to Greece is often easier when you compare the whole journey rather than focusing on one airport or island. Fares can vary considerably between Athens, Thessaloniki and holiday-focused destinations such as Heraklion, Rhodes and Kerkyra, so it is worth checking several Greek airports if your plans are flexible. A flight to Athens may also be useful for reaching other parts of the country, although any onward travel should be included when comparing the overall cost and convenience.

Travel dates have a strong bearing on availability, particularly around UK school holidays and the busier summer period, when demand for Greek islands tends to rise. Travelling outside the main holiday peaks may offer more choice, while spring and autumn can suit travellers who do not need guaranteed beach weather. Your UK departure point matters too: compare airports within reasonable reach of home, including regional options, but allow for rail fares, parking, luggage costs and an overnight stay if an early departure is involved. It can also pay to compare nearby alternatives such as Sitia alongside Heraklion, or Kefallinia, Zakinthos and Kalamata when planning a western or southern Greece trip, provided the additional transfer remains practical.

When comparing flights to Greece from the UK, the most convenient option often depends as much on your departure airport as on the destination itself. Consider the total journey from home, including transport and parking at the UK airport, terminal changes and the effect of travelling at a less convenient time. A nonstop itinerary may not always be the best value once baggage, airport transfers or an overnight connection are included, so compare the complete journey rather than the headline fare alone.

Choose the Greek arrival point according to where you need to be. Athens is useful for travel onwards on the mainland, while Thessaloniki may be more suitable for northern Greece. For Crete, compare Heraklion and Sitia based on your final location and the ground journey required after landing. Kerkyra, Rhodes, Kefallinia, Zakinthos, Syros Island and Kalamata can each reduce unnecessary overland travel when they are close to your intended base, but availability and connection arrangements should be checked for your dates.

Pay close attention to whether a booking is a single protected itinerary or separate tickets, particularly when changing in Athens or another airport. Allow for baggage collection, security and possible delays between flights, and check how you will reach your accommodation from the Greek airport. Comparing transfer time, connection risk and UK airport access alongside the fare usually gives a clearer picture of the most practical choice.
