I remember one of the first email's I got requested it...
You will be required to submit a complete official transcript prior to appointment,
if selected for hire. Official CTI transcripts can be mailed to:
Aviation Careers Division, AMH-300
Attn: CTI Program
6500 S. MacArthur Blvd
Oklahoma City, OK 73169
This was in the email with the job code, post ATSAT
Sounds to me as if they want to have already had it.... I will be mailing mine this week.
