That's been my experience -- no credit for partner flights flown before joining the target FF program in which you're trying to claim credit.
The original poster's dilemma is lack of membership in
any FF program.
For example, AS would not give me partner credit for BA flights flown before joining the AS program. Same response from CO when requesting credit in OnePass for DL flights flown even three weeks before joining OnePass.
Obviously, two program examples does not a statistically valid sample make, so of course YMMV.
