Answer 1

You mean Flight attendant. Yeah, sure. My mother was one. Ask the airport if you could be a flight attendant, they probably give you training and all the good stuff. It doesn't matter what your studying either. Just need a passport (duh!) and training.

Answer 2

Are you a Greek citizen, or at least fluent in Greek?  Most European Union countries require you to be an EU citizen, and some countries require you to be a citizen of their country to work for their airlines.  There's no sense pursuing the job if you're not qualified.
