{"slug":"american-express-vs-mastercard","title":"American Express vs Mastercard","url":"https://www.aversusb.net/compare/american-express-vs-mastercard","faqCount":5,"faqs":[{"question":"What is the main difference between American Express and Mastercard?","answer":"American Express is a closed-loop network — it issues cards directly, sets rewards and terms, and manages merchant relationships itself. Mastercard is an open-loop network that processes transactions between banks; card terms, rewards, and customer service are set by the issuing bank (Chase, Citibank, etc.), not by Mastercard."},{"question":"Is American Express accepted everywhere?","answer":"In the US, AmEx is now accepted at approximately 99% of merchants that accept credit cards. Internationally, acceptance is slightly lower — particularly at smaller merchants in Europe and developing markets where Mastercard's network is broader. AmEx occasionally gets declined at grocery stores and gas stations due to higher merchant fees."},{"question":"Why does American Express charge higher fees to merchants?","answer":"AmEx charges merchants a higher discount rate (typically 2.5-3.5% vs Mastercard's ~1.5-2%) because AmEx cardholders tend to spend more and AmEx funds richer rewards programs. This is part of the closed-loop model where AmEx captures more value from both sides of the transaction."},{"question":"Which is better for travel rewards — AmEx or Mastercard?","answer":"American Express Membership Rewards (earned on AmEx cards) are widely considered the most versatile travel points, transferring to 20+ airline and hotel programs. However, Mastercard-branded cards from Chase (Sapphire Reserve) and Citibank also offer strong travel rewards. The best travel card depends on which specific card and issuer, not just the network."},{"question":"Do I need both American Express and Mastercard?","answer":"Many experienced users carry both. A common setup: AmEx (Gold or Platinum) for dining, travel, and premium benefits; a Mastercard or Visa with no annual fee for merchants that don't accept AmEx, international travel, or everyday spend where AmEx rewards don't add up. The combination covers both premium perks and universal acceptance."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/american-express-vs-mastercard#faq","url":"https://www.aversusb.net/compare/american-express-vs-mastercard","inLanguage":"en-US","name":"American Express vs Mastercard — FAQ","description":"Frequently asked questions about American Express vs Mastercard","dateModified":"2026-09-15T09:00:06.813Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/american-express-vs-mastercard#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","@id":"https://www.aversusb.net/compare/american-express-vs-mastercard#faq-speakable","cssSelector":[".faq-answer"]},"mainEntity":[{"@type":"Question","@id":"https://www.aversusb.net/compare/american-express-vs-mastercard#q1","name":"What is the main difference between American Express and Mastercard?","answerCount":1,"acceptedAnswer":{"@type":"Answer","@id":"https://www.aversusb.net/compare/american-express-vs-mastercard#a1","text":"American Express is a closed-loop network — it issues cards directly, sets rewards and terms, and manages merchant relationships itself.
