The first time I flew to the Netherlands was also the first time that I flew out of the country. I remember how cool it was go to the post office and get my picture taken for my passport, and waiting for it to arrive in the mail. (And nervously waiting for them to return my birth certificate, which they did.)
The first time I had a very short stop in London to visit another friend, so each way I flew British Airways. On the flight to London I secured an exit row seat, which was nice for the sleeping aspect. On the way there, flights generally take 6 1/2 or 7 hours from NY. On the way back to the States, it takes a bit longer due to head wind. I like to take a red eye flight (6:10PM or 9:30PM are the choices) when heading to the Netherlands and on the way back I take a late morning flight.
