Please forgive me if these questions seem obvious - this is my first trip to out of the U.S. and I'll be travelling alone so I want to make sure I understand everything.
I have an 8am KLM flight out of CDG to Amsterdam and then on to Dulles (Wash DC). I'm scheduled to arrive in Amsterdam at 9:20am and my next flight (also KLM) leaves for Dulles leaves at 1:15pm. Do I go through any other checkpoints in Amsterdam or should I be fine to just switch gates? Based on my understanding, my checked luggage should go straight through to Dulles. Do I need to do anything at Amsterdam as far as entering the US or does all that happen at customs once I'm at Dulles? My flight to Paris is nonstop and I didn't consider any potential issues with international transfers before I booked my ticket.
I will be staying in central Paris the night before my departure and plan on taking a cab to CDG. I had planned to have a cab meet me at 4:30am but after reading a few horror stories about lines and general confusion at CDG I am wondering if that is too late - should I go for 4 am or even earlier than that? I assume it won't be a problem for me to get a cab that early in Paris?
