yes, a bit odd. Most of the time people are trying to get credit posted. Now I want to uncredit miles posted to my account.

Why?

I have 4 flights posted to Delta, switching to Flying Blue because it makes more sense for me. In fact with these 4 segments I'll go directly to silver.

Delta don't want to 'uncredit' the flights so FlyingBlue can pick them up.

I guess I can understand why... my reason which I was transparent about, didn't see compelling.

Any ideas on who-where-how in Delta to make this happen?

TIA
