Also via Free Frequent Flyer Miles, as always the Hilton American Express has no fee. Now there’s an offer of 15,000 bonus miles with first use.
As I’ve explained before, American Express is pretty good at figuring out who they’ve given signup bonuses to in the past. If you previously signed up for a Hilton Amex with a 10,000 mile offer you’ll probably get only 5,000 more points this time — that is, you’ll get the difference between what’s on offer now and what you’ve gotten in the past.
In my experience, Bank One (actually now JP Morgan Chase) and Citibank are pretty good for giving multiple signup bonuses…
