This is my first time flying Aegean Air and I had a great first time experience. I will fly this airline again.

There was not any food and I didn't use the entertainment

Just ok. No much of a great travel experience. If you need point A to B they are ok.

Η πτήση εμφάνισε μεγάλη καθυστέρηση και λαμβάνοντας υπόψη το γεγονός ότι επρόκειτο για την τελευταία βραδυνή πτήση, ήταν ιδιαίτερα κουραστικό για τους επιβαίνοντες.

More leg room, great if crew could move people before flight (ie if 3 in a row, offer to move 1 or 2 to an empty 3 seat row rather than let people move themselves after takeoff

Very bad experience during the boarding, the Aegean employees were very rude, and impatient with the passengers

Θα πρέπει να υπάρχει εστίαση στη γρήγορη και εύκολη επιβίβαση/αποβίβαση

aegean took off late, which made it impossible for us to make the next flight on air canada, we all ran to the terminal, the plane was still there but the air canada folks wouldn't let us board because they said the door was already closed. they told us we had to go all the way back to aegean desk to arrange another flight.

different entrance during the boarding for gold members and business class

Our flight was canceled after we paid in full and began making further plans. we were refunded only around75% of what we paid! I strongly recommend against ordering Aegaen Airlines!
