ATH-CDG-ATH in Economy. OA can vary quite a lot from one flight to another. On Both legs we had some very old 734, which were both very old and worn. On the first leg, the service was miserable. Even though the food was correct, the flight attendants seemed bored and totally uniterested. One of them thought actually that I was a foreigner, she started explaining me that I had to put my luggaga in the overhead bins, in an awful english, and when I told her I spoke greek, she told me " why didn't you tell me sooner!". And another spilled tea over my hands, without any excuse. The return flight had somewhat better FA, but OA has to improve itself in order to compete with other carriers.
