We're flying home to Seattle from Athens next spring, and we have two Delta flight choices. One is through CDG with 1 hour and 50 minutes between flights. The other is through JFK with two hours and a half between flights. We'd rather do our US entry at the end of the trip, in Seattle, but only if the 1 hour 50 minute connection in CDG is likely to be adequate (after a 3 1/2 hour morning flight from Athens).
Our question to experienced flyers is, which route would you choose? One with a 1 hour 50 minute layover at CDG, or one with a 2 hour 30 minute layover (including US entry) at JFK? Should we expect to change terminals at either airport? Does Delta do a good job with these connections?
Of course, missing either connection wouldn't be the end of the world. There are worse places to be stuck than Paris and NYC! :-)
