Has anyone had experience flying Veuling from Orly Paris to Florence? Or any other airline perhaps into Pisa?
Try Vueling Airlines from Paris-Orly Airport. It's the only budget carrier I see going into Florence.
The other popular airport to fly into is Pisa, one hour west by train. EasyJet.com also flies out of Paris-Orly. Both are good airlines.
AirFrance flies from CDG to both Florence and Pisa (I'm sure the most expensive option). RyanAir flies from Paris Beauvais (over 1 hr from Paris) to Pisa. All the options have been mentioned. The fastest and easiest is Vueling to Florence.
