I sent my passport in to be renewed last Monday 6/4, I paid the $60 expedite fee and overnight mail for both directions. It didn't appear on the online status check until today (Wed 6/13), when it said it had been processed and would be delivered tomorrow 6/14. But it was in my mailbox when I got home today.

All told, eight calendar days door to door. Sancha is a very happy camper.
