It may also be a case as TWA884 pointed that even for those with TSA Pre, they may still be randomly directed to the "regular" line. So the lesson learnt here (for me at least) is not to leave the check-in counter and ask the agent to double check!
Interesting. Thanks for the reference.
TTP/Pre enrollment
increases your chances for TSA Pre, it does not
entitle you to it.
Determination for Pre is made by DHS/TSA for each flight. If Pre is approved, the airline would encode the PreCheck indicator onto the BP barcode and print a Pre logo as well.
So it is possible TSA approved you for Pre for this fight but AA had issues encoding/printing the logo. So in this scenario, if the checkpoint was a scan ID-only but not BP model, then
any of your identification including DL/passport would have pulled your trip from TSA records showing you were approved for Pre. If this was a traditional scan BP checkpoint and BP didn't have Pre indicator, you are not entitled to Pre even if presenting a TTP card.
Again being enrolled in TTP/Pre and/or presenting a TTP card
does not entitle you to Pre.
Here is the link again in case you didn't open it the first time.
