You will find that most airlines have interline agreements with most other airlines, that does not mean to say that they will interline baggage for separate tickets though.
Fascinating. Is this documented anywhere? Potentially I would also need to do this in reverse - would love to see if Turkish has a baggage interline agreement with AA/BA to do the same.

AIUI, baggage interline agreements were basically set up to facilitate interline connections - true connections, that is, written on one ticket (or a series of conjunction tickets). So if you buy a ticket with a (true) interline connection, you should normally be entitled to interline baggage transfer even if the airlines concerned aren't partners in any alliance sense.
If there's a baggage interline agreement in place, it also means that the airlines can through-check bags even if the travel is not a true connection because it's written on two separate tickets. But they're not obliged to do this and it's a matter of policy and discretion.
So in
shorthauldad's example, CX would normally
have to interline to a *A airline with which it has a baggage interline agreement, if the travel is on a single ticket. It does so as a matter of discretion if the "connection" is on separate tickets.
In contrast, BA has chosen as a matter of policy to interline bags when there are separate tickets only if the second flight is another OW airline.
And there are other airlines which have chosen as a matter of policy not to through check any bags on separate tickets, even when the second flight is another flight on the same airline. (And I'm not talking about low-fare airlines here.)
