Of course perhaps I should have used my Delta card to avoid any clawbacks. It's not like the 5x points are worth the risk for a charge of $5.60 in taxes.
There's no requirement you need to actually use your DL Amex card to purchase the awards. The DL Amex first bag free checked luggage benefit also does not require you purchase ticket with your DL Amex card (it will be applied to any DL operated and marketed flight with your name and Skymiles number on it).
