Does anyone know what the Remarks / Observations codes on AC's boarding passes mean? I assumed they reflected an individual's status. When I was Elite mine would read AC*E. I'm finally remade Elite and now mine reads "AC*A/L T07". Curious if anyone knows what this means. Does it mean I was Prestige when I booked the flight and now have 07 Elite status?

Also, there's always an "AP" after my last name. Anyone know what that stands for?

Thanks in advance.
