What is the best way to travel from Rome to Paris Train or Plane?

EasyJet flies Paris Orly (ORY)to Rome Ciampino (CIA)and Air Berlin flies Paris CDG to Rome FCO. For budget flights - www.whichbudget.com or www.skyscanner.net

We took the night train and thought it was great. What I like is that the train stations are right in the city so there's no additional travel time to an airport.

Trains also have a lighter global warming impact than short flight jets so for me that was the final straw that tipped us to the train ride.

Be aware that the Air-Berlin flights are through Vienna

If you want to fly try ryanair.com Wonderful rates from Ciampino..I am flying Rome-Paris in June for around $90.00 round trip. We have taken the train many times from Paris to Rome but not the other way around. We really enjoyed it. It was a night train leaving around 7 and arriving in Rome around 9 the next morning. Dinner in the dining car was lovely. We are doing this again in May. Price runs around $220.00 per peron..Flying will be less expensive..But the train experience is really wonderful

I didn't list Ryan Air because the airport they use isn't in Paris. It's an hour from the city.
