Baby Swede's passport expires in March 2022. No immediate int'l travel plans (sky-high prices to the Caribbean over Thanksgiving and Christmas squashed those ideas), but I still paid for expedited service just in case.
7/23 - Miraculous found an evening weekday appointment for 8/19 at the USPS Altura Facility in Aurora, CO
8/19 5:30pm - Took Baby Swede to get her passport renewed; Mrs. Swede had to attend Miss Swede's back-to-school night, so we got the DS-3053 form filled out
8/19 6:00pm - Arrived and knocked on the door; USPS employee confirmed name and let us in
8/19 6:05pm - Ask to approach the desk; USPS employee looks over everything and rejects the application. DS-3053 was filled out with blue ink, not black. Ugh.
8/19 6:10pm - USPS employee was super helpful, and said everything else was acceptable.
8/19 6:10pm - He also said that
walk-ins are accepted first-come-first-serve between 9-11am every Tuesday through Saturday, but he did warn that people line up super early. It's not the Aurora Passport Agency, but hey.
8/19 7:00pm - Came home and hopped on my laptop to find another passport appointment that wasn't in the middle of the weekday 100 miles away
8/19 7:02pm - Book appointment for the next morning at 7:45am at the same USPS facility!

8/20 6:45am - Baby Swede, Mrs. Swede, and I drive back to Aurora
8/20 7:25am - Arrive and knock on the door; we're let inside
8/20 7:32am - The 7:30am appointment doesn't show up, so we're processed
8/20 7:45am - Back out the door
Props to the employees at the USPS Altura Facility. They run a super efficient operation.
tl;dr - if you don't want to drive to rural Colorado, you might want to give the walk-in line at the USPS Altura Facility a try
