Large parts of Greece have literally been covered in snow in the last few days. Because this doesn't happen very often, many airports are poorly prepared for winter conditions. As a result, flights have to be cancelled.
The country's largest provider, Aegean, decided on Monday to cancel most flight connections. Domestic flights operated by subsidiary Olympic Air are also affected. Since Tuesday, 12:00 p.m., regular operations have gradually started again.
On Monday, the Aegean Group only operated flights from Thessaloniki to Frankfurt, from Larnaka to Athens, from Frankfurt to Athens and from Thessaloniki to Stuttgart and back. Due to the fact that aircraft are currently still at the "wrong" airports, it may take a few days for the flight plan to finally stabilize.
