Applied 9-11
Conditional Approval Received 9-15
Appt Scheduled for 9-21 (Gulfport, Miss - NOW ATLANTA)

Wanted Atlanta as its a couple hours closer. Could have scheduled for 9-19 in Gulfport which would have been 8 days from application to appt. Couldnt make it till the 21st due to work conflicts.

Dont know if it makes a difference but I was already TSA Pre for the last few years.

EDIT: By checking the GOES site over the last several hours an appt became available at the Atlanta Airport location on 9-21. I snagged it right away saving me 4+ hours of drive time. All the advice in this forum about continuing to check for alternate dates/times is 100% accurate. Thanks to everyone who suggested this.
