Aegean has started a new promo with Cosmote, where every month a discount code can be had offering 30 euro off a number of destinations. This month:

Bookings 01-30 sept, flights 01-31 oct for: Venice, Paris, Amsterdam, Madrid, Rome, Istanbul, Beirut, Izmir, Moscow from/to Athens and Stuttgart from/to Thessaloniki. That brings down a roundtrip to AMS to <100 euro.

Next month other destinations will be on offer. Since its a discount code it presumably can be combined with other sales.

It does require a roundtrip, however it is unclear if also the return needs to be within the specified month (October in this case). Has anybody already tried?
