must one fly out of CDG rather than Orly to get any inexpensiv non-stop flight or a no change flight from Paris to Florence. I can find only one Yueling flight that flies very late at night. I know about Pisa on EasyJet but hoped to fly into Florence Thank you.
Two non stop alternatives only from Paris to Florence FLR: AirFrance from CDG (6 flights daily each direction)
Vueling from ORY (1 flight daily each direction) The Vueling option arrives after 7pm (well after 8pm on Sundays). That's it. Any other non stop option will have to contemplate the use of other airports nearby, such as Pisa or Bologna, both located at about 70 min. bus ride from Florence.
Must one ?? Of course, if that is the schedule. We don't have any magic ways to rearrange airline schedules. Nice if we did and could always arrange direct flights from anywhere to anywhere.
From Paris itself, getting to CDG from Paris takes only a bit longer than getting to ORY. I would choose whichever had the flight you needed. The "bad" airport is Beauvais, which is an hour and a half from Paris. Of course, if you're coming from somewhere else (say, driving from the south rather than being in the city), it could make more of a difference.
