I just read that a US passport costs 110$ + 25$ execution fee.
It also takes 4-6 weeks (!!!) to get it, using the standard procedure.
Here, the fee is already included in the 100$ and it takes a week or so to get it (my mum waited 4-5 days last year).
As is very fitting for the United States, one may pay an additional fee for faster service. When I was in college, I decided fairly spontaneously to visit a friend who was studying abroad in the UK. I think it was about an extra $50 to get it in just a week or two. Now that the Schengen Agreement has been in place for a while, I wonder if those living on the continent are any less likely to get a passport. Perhaps if the UK and Ireland were willing to join. When I was in UK, we decided to go to Germany for the weekend, and (not being all that informed on European affairs) I remember being surprised that I had to use my passport again.
