I have travel booked for 8/23. My daughter's passport needs to be renewed. I was able to get an appointment at the Passport Agency for 8/23 at 11:00 AM, nothing sooner. In order to make my flight I would have to be out of the passport agency by 3PM or so. Is this possible? I was not able to get a real answer from the person who made the appointment for me but they recommended I go ahead and book the appoitnment. I have been to the passport agency before, prepandemic, and I did get my passport back same day but I don't recall how long it took as it was many years ago. I considered changing my flight for a day or two later but United says it will cost over $2k to change.
