The features that matter most when you travel abroad
The best credit card for international travel is one that charges no foreign transaction fees, gives you a good exchange rate, and works reliably outside the US. Most major card networks — Visa, Mastercard, American Express, Discover — work in most countries, but the card issuer's fees and how they handle currency conversion make the real difference in what you actually pay.
A card with no foreign transaction fee saves you 1% to 3% on every purchase abroad. That fee is separate from the exchange rate your bank uses, and it adds up quickly on a two-week trip. Beyond fees, you want a card that doesn't lock you out of your account when you travel, doesn't charge you to use foreign ATMs, and ideally gives you travel protections like emergency card replacement or lost luggage coverage.
Key Takeaways
- Foreign transaction fees range from 0% to 3% per purchase and are charged by the card issuer, not the merchant or your bank — so a card with no foreign transaction fee saves money on every transaction abroad.
- Notify your card issuer before you travel so they don't block your card thinking it's fraudulent, and ask whether they charge ATM fees in foreign countries.
- Rewards cards that earn cash back or points on travel purchases can offset the cost of flights and hotels, but only if you pay the full balance each month.
- Travel insurance benefits like emergency card replacement, emergency medical coverage, and trip delay reimbursement are often included free with premium travel cards.
- Visa and Mastercard are accepted almost everywhere internationally, while American Express and Discover have smaller networks outside major cities and tourist areas.
No foreign transaction fees versus rewards
You have two main types of travel cards to choose from, and which one makes sense depends on how you use credit. A no-fee travel card charges 0% foreign transaction fees and typically offers a modest cash back rate (0.5% to 1.5%) on all purchases. These cards are straightforward: you save money on every transaction abroad, and you don't need to carry a balance or hit spending targets to get the benefit.
A rewards travel card often charges a foreign transaction fee (usually 0%) but earns higher cash back or points on travel-related purchases — flights, hotels, rental cars — and sometimes on dining and gas at home too. These cards often come with an annual fee ($95 to $450) and require you to pay your full balance each month to avoid interest charges that wipe out the rewards. If you travel frequently and pay off your card every month, the rewards can cover the annual fee and then some. If you carry a balance or travel rarely, the fee costs more than you'll earn back.
The math is straightforward: if you spend $5,000 abroad on a no-fee card earning 1% cash back, you get $50. On a rewards card with a $95 annual fee earning 3% on travel, you get $150 minus the $95 fee, leaving $55 — but only if you don't pay interest. If you carry a balance at 18% APR, interest charges will quickly exceed any rewards you earn.
How foreign transaction fees and exchange rates work
When you use a credit card abroad, two separate charges happen. First, the merchant's bank converts the local currency to US dollars using an exchange rate. Second, your card issuer adds a foreign transaction fee — typically 1% to 3% of the purchase amount — on top of that converted total. The exchange rate itself is set by the card network (Visa, Mastercard, etc.) and is usually close to the real market rate, so the main variable you control is the foreign transaction fee.
A $100 purchase in euros might convert to $110 USD at the real exchange rate. If your card charges a 2% foreign transaction fee, you pay $110 plus $2.20, totaling $112.20. A card with no foreign transaction fee charges only $110. Over a two-week trip with $5,000 in purchases, a 2% fee costs you $100 in extra charges.
Some cards also charge ATM fees when you withdraw cash abroad — typically $3 to $5 per withdrawal plus the foreign transaction fee. If you plan to use ATMs, look for a card that waives foreign ATM fees. A few premium travel cards reimburse all ATM fees worldwide, though this benefit usually comes with a higher annual fee.
Travel insurance and emergency benefits
Many travel cards include insurance and protections that you don't pay extra for. Emergency card replacement means the issuer will send you a replacement card to your hotel or a local branch if your card is lost or stolen. Emergency medical and dental coverage reimburses you for unexpected medical or dental treatment while you're abroad — useful if you get injured or have a dental emergency far from home. Trip delay reimbursement covers meals and lodging if your flight is delayed more than 12 or 24 hours.
These benefits vary widely by card. A basic no-fee card might include only emergency card replacement. A premium travel card ($300+ annual fee) might include emergency medical coverage up to $250,000, trip cancellation reimbursement up to $10,000, and baggage delay coverage. Read the benefits guide for any card you're considering — it's usually available on the issuer's website — to see exactly what's covered and what the limits are.
Travel insurance is not a reason to choose a card by itself, but it's a real benefit if you're already paying an annual fee for rewards. If you're choosing between two similar cards, the one with better travel insurance tips the balance.
Visa and Mastercard versus American Express and Discover
Visa and Mastercard are accepted at the vast majority of merchants worldwide — restaurants, shops, hotels, ATMs. American Express and Discover have much smaller networks outside the US, especially in smaller cities, rural areas, and developing countries. If you're traveling to Europe, Japan, or Australia, American Express will work in most places, but you may hit merchants who don't take it. If you're traveling to Southeast Asia, Central America, or Africa, Visa and Mastercard are far more reliable.
The safest approach is to carry two cards: a Visa or Mastercard as your primary card, and a second card (American Express, another Visa, or a backup Mastercard) in case one is lost or a merchant doesn't take it. This also protects you if one card is temporarily blocked for fraud. Never carry only one card when traveling internationally.
Notifying your bank and protecting your card abroad
Before you leave, call your card issuer and tell them the dates and countries you'll be visiting. Card issuers monitor for fraud by looking for unusual spending patterns — a purchase in Tokyo followed by a purchase in Paris six hours later is a red flag. If you don't notify them, your card may be blocked mid-trip, and getting it unblocked from abroad is time-consuming and stressful.
When you notify your issuer, also ask: Do they charge foreign ATM fees? What's their 24-hour customer service number outside the US? Can they send a replacement card to a specific address or hotel? Will they reimburse fraudulent charges if your card is used without permission? Most issuers cover fraudulent charges, but the process and timeline vary.
While traveling, treat your card like cash. Don't leave it unattended at a restaurant or shop. Use ATMs in well-lit, find locations — inside banks or shopping centers rather than on the street. If your card is lost or stolen, call your issuer when ready using the number they gave you before you left. The sooner you report it, the sooner they can block it and send a replacement.
Comparing cards: what to check before you choose
When you're looking at specific cards, make a straightforward list of what matters to you. If you travel once a year and want simplicity, prioritize a no-fee card with no annual fee and Visa or Mastercard acceptance. If you travel frequently and pay off your balance every month, look at rewards cards and calculate whether the annual fee is worth the cash back or points you'll earn. If you travel to remote areas or developing countries, choose Visa or Mastercard over American Express.
Check the issuer's website for the benefits guide, which lists foreign transaction fees, ATM fees, travel insurance coverage, and emergency services. Compare at least two or three cards before you decide. Many issuers offer the same card with different annual fees and rewards rates — for example, a basic version with no annual fee and a premium version with a $95 fee and higher rewards. The basic version is often the better choice unless you travel very frequently.
Once you've chosen a card, explore at least two weeks before your trip. Card approval usually takes three to five business days, and you want time to receive the physical card, set up online access, and notify the issuer of your travel plans.
Frequently Asked Questions
What if I don't have a credit card yet and I'm leaving soon?
explore for a card when ready — most issuers approve applications within three to five business days and can rush a card to you for a fee (usually $15 to $35). If you're leaving in less than a week, call the issuer after you're approved and ask if they can expedite the card or provide a temporary card number you can use online. If that's not possible, bring a debit card and a small amount of cash as backup.
Should I use my debit card or credit card abroad?
Use a credit card for purchases whenever possible. Credit cards offer fraud protection — if your card is used fraudulently, you dispute the charge and the issuer investigates. Debit cards offer less protection, and fraudulent charges come directly out of your bank account. Debit cards also often charge foreign transaction fees and ATM fees. Use a debit card only to withdraw cash from ATMs if your credit card charges ATM fees.
What's the difference between a travel card and a cash back card?
A travel card earns rewards specifically on travel purchases (flights, hotels, rental cars) and often includes travel insurance and emergency services. A cash back card earns the same percentage on all purchases or higher percentages on specific categories like dining or gas. For international travel, a travel card's benefits like emergency card replacement and medical coverage matter more than the rewards rate.
Can I use my credit card to pay for everything, or should I carry cash?
Carry a small amount of local cash (the equivalent of $50 to $100) for taxis, tips, street vendors, and small purchases at places that don't take cards. Use your credit card for hotels, restaurants, and larger purchases. Some countries and regions rely more on cash than others — ask your hotel or a travel guide for the specific country you're visiting.
What happens if my card is declined while I'm traveling?
Call your card issuer's international customer service number when ready — you should have this number before you leave. A decline usually means fraud protection triggered or a temporary system issue. The issuer can verify the charge and reactivate your card on the phone. If your card is damaged or lost, ask them to send a replacement to your hotel or a local branch of their bank.
