However, these cards let you access perks your current Visa and Mastercard don’t offer. Also, depending on what you want out of a card and where you travel, one of the Amex cards may go further than another card.Premium Travel BenefitsMost Amex credit cards are ideal for travel rewards. American Express, Chase, and Citi both offer a premium travel credit card offering perks like travel fee credits, airport lounge access, and flexible point redemption options.The Platinum Card® from American Express (Read our in-depth Platinum Card from American Express review for more details) offers the most benefits for the various premium credit cards.

You must have an active Delta Air Lines itinerary to enter Delta Sky Club, for example.Membership Rewards Point TransfersMost American Express credit cards earn Membership Rewards points on all purchases. These points are most valuable when redeemed for award travel or gift cards. Each card is worth 1 cent when booking award flights on AmexTravel.com. A better option can be transferring them to an airline or hotel partner and booking your next trip directly from the travel brand.Many of these partners let you transfer Membership Rewards at a 1:1 ratio to your linked loyalty account:Aer LingusAeromexicoAeroplanAir France KLMAlitaliaANAAsia MilesAvianca LifeMilesBritish AirwaysDelta Air LinesEl Al Israel AirlinesEmiratesEtihadHawaiian AirlinesIberiaJetBlueQantasSingapore AirlinesVirgin AtlanticChoice PrivilegesHilton HonorsMarriott BonvoyAmerican Express offers more transfer partners than Chase, Citi, or Capital One.

You earn:3% cash back at U.S. supermarkets (up to $6,000 per year in purchases, then 1%)3% cash back at U.S. gas stations (up to $6,000 per year in purchases, then 1%)Plus, 3% cash back on U.S. online retail purchases (up to $6,000 per year in purchases, then 1%)1% cash back on general purchasesCash back is received in the form of Reward Dollars that can be redeemed for statement credits.

Limited-Time Welcome BonusesAmerican Express is more likely to offer limited-time bonus offers on their various travel credit cards.The co-brand credit cards for Delta Air Lines, Hilton Honors, and Marriott Bonvoy are the most likely to offer enhanced welcome offers. However, you should always look for revamped cards like the American Express® Green Card that might have other flexible perks. With the American Express Green Card, you could earn 3x points on eligible travel and 3x points on dining worldwide along with other perks like CLEAR membership and lounge access.Current American Express rules only let you earn a credit card’s welcome offer once. Even if you cancel your card and wait at least 24 months, you won’t qualify to earn a repeat bonus. Timing your application to earn a limited-time offer is a great idea as you will never earn that card’s bonus offer again.Flexible Application RulesThe American Express credit card application rules are less restrictive than other banks. For example, Chase will decline your application if 5 or more credit card accounts have been added to your credit report in the last 24 months.The two “best practices” you should be aware of. First, only apply for two Amex credit cards every 90 days. Also, wait at least 5 days if you apply for two cards within a week.Like several other banks, Amex only lets you own up to five American Express credit cards at one time.Once again, the biggest restriction can be their welcome offer restriction. Because you can only earn a card’s welcome bonus once, it can be worth waiting until Amex offers a larger-than-usual offer.Amex OffersAnother shopping benefit of an American Express credit card is their Amex Offers program. You will receive curated offers for stores, restaurants, and travel to earn cash bonuses. Chase has a similar rewards program for the branded and Ultimate Rewards credit cards.These offers plus access to unique experiences and ticket pre-sales for Amex-sponsored events are some fringe benefits of your American Express credit card.Check out some of the best American Express credit cards and the best Amex business credit cards to learn more about which card might be best for you.SummaryMany people are hesitant to get an American Express credit card because they might think you must wait to get an invitation to apply.
