I wasn't able to OLCI today for a flight to Canada tomorrow.
At first I was told it was because I had Alaska Air flights on the return (?) but after being transferred to the IT desk I was told it was a TSA issue and they wanted to verify my passport info.
I travel a lot though & this has never been an issue before.
So I was not able to OLCI & will go stand in a line tomorrow instead.

Update: I tried again to OLCI some 12 hours later & was able to do so successfully. Not sure why I couldn't do it this morning but at least I can go directly to the gates now for a 0600 flight.
