Just want to be clear here: Why do I need the Amex card for earning vacation mqd during the challenge but not for outside of the challenge? I can live with Delta wanting to discourage instant Gold with a single vacation, but that's sneaky.
Are we sure this is correct as written? I don't put any stock in what Delta's customer support says, but they say the site is wrong.
If I need to get the card, that's an extra week or two of lead time I need to plan for before even booking. Offers are elevated at the moment and it might work in my favor.
