Running into the same thing, transferred 420k points yesterday and nothing. Tried calling back and forth before finding this and have Capital One blaming Flying Blue, and vice versa. With Amex, I transfered 92k instantly to Flying Blue and transfered 260k from Chase and it happened instantly. Don't think I'll keep my Venture X after this, it was hard enough to find award travel to book with C1 transfer partners. Only two tickets left at the price so hoping it comes soon.
