If you have upcoming travel, you can call the passport agency and say so, they will ask you for date of travel and will get you an appointment at the closest passport center. They can often do same day or next 1-3 biz days, depending on your date of travel. You will be expected to submit proof of travel (such as airline reservation, could even be fully refundable) and you'll have to pay an extra $60 for the quick turnaround.
