New Passport

Yay! I got my new passport in the mail yesterday. I think it took only 3 weeks for them (State Department?) to process and return to me. I still have to get my old passport back but they said it may come in a separate mailing. I opted for the larger 52 page passport since I had to add pages to my last one. It used to be free to add pages but now the government charges $82 to add 24 pages to your existing passport.

Will they add another 24 pages to my 52 page passport if I need it?
