If you have an American Express Membership Rewards account, you can transfer points to participating frequent travel programs, one program being your Hilton Honors account. Usually one Membership Rewards point equals 2 Hilton Honors points. So 1,000 American Express Membership Rewards points will yield 2,000 Hilton Honors points.
However, now through 03/31/2022, you can receive 30% more Hilton Honors points when you transfer Membership Rewards points to your Hilton Honors account. So during this offer, 1,000 American Express Membership Rewards points will yield 2,600 points.
If you are trying to accumulate Hilton Honors points right now, this may be something you may want to consider taking advantage of.
