Olympic Air announced this week it would be stopping its Athens-Thessaloniki and Athens-Iraklio service from the fall, as well as cutting the connection between the southeastern Aegean island of Rhodes and the Greek capital.

In a letter to agents and associates, Olympic said it will stop conducting flights from Athens International Airport to the northern port city of Thessaloniki and to the city of Iraklio in Crete from October 13, a few days after suspending its Athens-Rhodes service on September 30.

Passengers with reservations for any flights to or from these destinations after these dates will receive a full refund. The company’s announcement also said that passengers could also switch their tickets to flights toward the same destinations operated by rival Aegean Airlines.

Olympic Air was founded by the Greek tycoon Aristotelis Onassis in 1957 as Olympic Airlines. Later on, as Olympic Airways it was the flag carrier airline of Greece for 35 years, operating services to 37 domestic destinations and to 32 destinations world-wide, including Melbourne and Sydney.

It was privatised in early 2009. Its operations were scaled down, aircrafts were sold and its name was changed to Olympic Air.
