I had much better luck with my application for a 52 page passport with expedited renewal. I had an upcoming international trip on 5/2, which I stated in my application. Not sure if that made a difference.

• Mailed application from California on Thursday 4/12 in the afternoon
• Delivered to Philadelphia processing center on Saturday 4/14
• Check cleared on Tuesday 4/17
• Received new passport on Saturday 4/21
• Received old passport on Tuesday 4/24

One mistake I did make was with my email address. I filled the form online. When you do that everything, including the email address I entered, is filled in all caps. I didn’t notice it until I printed and mailed the application form. Because my email was in all caps, I never received notification about the application. However, I was able to go online to https://passportstatus.state.gov/ and manually enter my info and get the status and also correct my email address.
