I just signed up for a mileage bonus for flights in and out of California - I hadn't realized it was available until yesterday. Because I didn't sign up I missed the bonus on four flights already and as the bonus miles per flight increase with each increment, this also means all future flights will earn me less miles.

Has anyone ever convinced the EXP desk to waive the restriction and have the offer backdated?

I am not saying I am entitled to this (I should have checked the offers more often), just wondering if there's any chance of success if I call.

The promotion is AAWCB by the way.
