Fly KLM fairly regularly (3 times per year minimum)- next flight is Oct 9th. I do regular TATLs and sometimes the best deal/most covenient is via AMS. Oct 9-15th it is MCI-MSP-AMS-MAN-ATL-MCI. Anyway, I think KLM are OK but IMHO,the DL domestic product is better. Schipol is a great interchange airport though.
