One way to accumulate Hilton Honors points is to transfer Citi ThankYou Rewards points to your Hilton Honors account. Generally, 1000 Citi ThankYou Rewards points equal 1500 Hilton Honors points, a ratio greater than 1:1.
Now through September 20, 2017, there is a limited time offer where you can get 2 Hilton Honors Bonus Points for each ThankYou Point you transfer. So with this offer, 1,000 Citi ThankYou Rewards points would yield 2,000 Hilton Honors points
