Trying again... waiting at Dulles for our flight-- we got there at 3:30 for our 7 pm flight, only to have it take off after 11pm... and to miss our connection in Paris... again.
As a side note: Flying Air France is super once you're on the plane. But their customer service leaves much to be desired on the ground. They left me on hold for ever (actually as long as I'd wait on the phone), and only have one song. The service is slow and unpredictable and not recommended. But in the air, the plane was in good shape, the food was good, the wine was good, the movie selection was fantastic, etc.
