Had something I’ve never had happen before this morning.

Aircraft change (lost my MCE seats, but that’s another complaint), and when I get to TSA, my pre check is gone. My fault for not checking at this point.

I go to the AA desk, and my DOB and global entry number have been confused with my travel partners. So it’s their day and month but my year and their KTN.

The desk managed to get it fixed, with my seat becoming unassigned for a time, on a full flight.

Had Aircraft changes before, but never had this.
