To link your American Express account to Hilton Honors for points transfers in 2026, you must first log in to your American Express online account and navigate to the "Membership Rewards" portal. Under the "Transfer Points" tab, select "Travel Partners" and locate Hilton Honors in the hotel category. If you are not already linked, click "Add My Existing Partner Account" and enter your Hilton Honors membership number along with your name exactly as it appears on your Hilton profile. The linking process typically takes between 3 to 5 business days for verification, though some users report it being near-instant. Once linked, you can transfer Amex Membership Rewards points to Hilton at a standard ratio—often 1,000 Amex points to 2,000 Hilton Honors points. Note that transfers must usually be done in increments of 1,000 points. After the accounts are successfully connected, you will be able to initiate transfers directly from the Amex website or mobile app. Ensure your personal details match on both platforms to avoid a "data mismatch" error that can delay the linking process significantly.
