The flight crew of Aegean were very nice. I travelled coach, so comfort and such is based on that. However, their ground crew have a serious scam going. I flew from Athens to Santorini with all carry on baggage, nothing checked. On the return flight to Athens my baggage miraculously was "too big" for the over head compartments and had to pay to check my bags. I even told them I didn't pay coming over. Their answer? "I don't care." They hit everyone going back to Athens like that...that's a serious money maker at a minimum of 40 Euros per bag.
