Upgrading your American Express Hilton Honors card is a straightforward process that can typically be done through your online Amex account or over the phone. If you hold the no-annual-fee base card, you can move up to the Hilton Honors Surpass® Card or the premium Hilton Honors Aspire Card. To check for an "Upgrade Offer," log in to the Amex website, go to the "Amex Offers" or "Benefits" section, or simply search for "Apply for an Upgrade." Upgrading is often better than a new application because it allows you to keep your existing account history and credit line, though you should look for specific upgrade bonuses (e.g., 100,000 points after spending $3,000). If you upgrade to the Surpass, you’ll get Gold status and a Free Night Reward after $15k spend; the Aspire offers immediate Diamond status and a free night every year. Note that you must usually have held your current card for at least 12 months before Amex regulations allow you to upgrade to a higher-fee version of the same "family" of cards, due to the CARD Act's consumer protection rules.
