I just got my USA Passport via USPS Priority Mail today (2/13/12), I just put the application in 2 Friday's ago on (2/3/12), Now That's Speedy!
Fun Facts: I got my pictures taken at Walmart for $10 vs. the USPS price of $15, I say this because ppl i've talked to think the photo will be rejected if anyone else but the USPS does it. My head is completely shaved, so is my face, I know ppl were wondering if you needed hair for the picture to see what you looked like with hair, I think they just go by facial features. I chose standard delivery/processing time which was 4 to 6 weeks. For the cruise i'm going on in August on RCCL Explorer of The Seas I had applied (check marked) I wanted a passport card too, the lady at the USPS Post Office scribbled that out saying it was a waste of money because cards are for business ppl who are traveling out of the country every week about.
I decided to go on a cruise 12/20 for a 2/26 cruise. My passport was expiring 2/2012. I shipped my passport out 12/27 wondering if I did the right thing and not pay extra for expedited service as opposed to the normal 6-8 week lead time. I decided not to use this service. I recieved my passport on 01/13; I kid you not.
