How many hours is a flight from Maryland to Paris France?

== == About 7 hours depending on the flight routing and airplane speed. You can get a more specific idea by going to one of the big travel sites like Expedia or Travelocity and entering a query for the flight you're interested in. You don't have to actually book; just cancel out of the session once you have the times. Of course you have to add a few hours to any time you come up with since you'll need to be at BWI 2 or more hours in advance, and CDG is a good half-hour or so train ride away from Paris itself.
