Def of status quo is “ existing conditions”. Conditions can change for a number of reasons, just as it did in 07 when the age went from 60 to 65. No where in any airline contract does it guarantee any of us will upgrade. Just like the flow thru to American, that can flow backwards. Also, I believe there were pilots who went from the left seat to right seat after 9/11 at many of the majors and spent a few years back in the right seat.
