are same day renewal passports still available with an appointment

Yes, depending on your travel date. If you are traveling in 3 days or less they will give it to you same day (be prepared to wait 3+ hours). If you are traveling in the next 5 days they may ask you to return tomorrow to pick it up.

How were you able to get an appointment? I’m trying to get an appointment and I leave in 5 days, but there are no available appointments!
