Europe flights

Hi girls,

I'm trying to pick flights to Greece and I think we're going to do one that stops in Italy or France and then goes to Athens, so it can be cheaper.

Does anyone know how much time you need inbetween flights to get through customs and what not.

When I flew to Australia and then took a domestic flight, I had to get my luggage and have it scanned and then re-check it for the domestic flight. Needless to say I missed the flight, so i want to be cautious.

Thanks!
