Best Credit Cards for International Flight Bookings: FX Fees, Points, and Protections
May 10, 2026
The cheapest flight fare and the right credit card are both part of the same optimisation problem. A 3% foreign transaction fee on a £800 flight costs £24. Booking the same flight on a card with no FX fee costs nothing extra, and if that card also earns 1.5 points per pound on travel spend, the difference compounds over time. This guide covers the key factors to consider and which card types tend to win.
The Three Variables That Matter
When evaluating a credit card for travel bookings, three factors dominate everything else:
1. Foreign transaction fees. The UK average credit card charges 2.75–3% on any transaction in a foreign currency. For a frequent traveller booking international flights several times a year, this adds up quickly. Premium travel cards, challenger bank cards, and most US travel cards waive this fee entirely.
2. Points or miles earn rate. Travel-branded cards typically earn accelerated points on flight and hotel bookings. The value of those points varies enormously by programme — a British Airways Avios earned on the BA Amex is worth more in premium cabin redemptions than in cash-back, but the earn structure and fees need to justify the spend.
3. Built-in travel insurance. This is the most undervalued feature of travel credit cards. Section 75 protection under UK consumer credit law already covers purchases over £100 made on any UK credit card — if an airline collapses, you can claim the cost back from your card provider. But premium travel cards go further: trip cancellation insurance, travel delay compensation, medical coverage, and sometimes missed departure protection.
No-Fee FX Cards: The Foundation
Every traveller should own at least one card with no foreign transaction fee, even if it doesn't offer rewards. These are your functional baseline.
In the UK, the Chase UK current account debit card waives all FX fees and ATM fees internationally (up to a monthly limit). It earns 1% cashback on spending for the first year. It's not technically a credit card — it's a debit card with prepaid credit functionality — but it solves the FX problem comprehensively.
Starling Bank and Monzo both offer current account cards with no FX fees on spending. These are ideal for in-destination spending and smaller overseas purchases, though they don't offer Section 75 protection on debit transactions.
For actual credit cards with no FX fees, Barclaycard Avios Plus waives foreign transaction fees while earning Avios. The annual fee (around £20/month) needs to be justified by Avios earning and the companion voucher benefit.
In the US, the landscape is even more favourable: most major travel credit cards — Chase Sapphire Preferred, Chase Sapphire Reserve, American Express Platinum, Capital One Venture X — have no foreign transaction fees as standard. US travellers booking international flights have a wide field of no-fee options.
Airline-Branded Cards: When They Make Sense
Airline credit cards (British Airways Amex, American Airlines AAdvantage, United MileagePlus, Delta SkyMiles Amex) offer accelerated earning in that airline's loyalty currency. They make sense when:
- You fly that airline often enough to reach meaningful tier status - The companion voucher or annual bonus miles offset the annual fee - The Avios or miles are redeemable for routes or cabin classes where they represent genuine value
The British Airways American Express (free tier, no annual fee) earns 1 Avios per £1 on everyday spending. Spend £12,000 in a year and receive a Companion Voucher — a two-for-one on a reward flight. For a couple who'd otherwise both pay full Avios rates on a premium cabin redemption, this can be worth hundreds of pounds annually.
The British Airways Amex Premium Plus adds a higher earn rate and a lower spend threshold for the Companion Voucher, but the fee is substantial. Calculate whether your actual spend unlocks the benefit before committing.
Points Transferability: The Most Important Long-Term Factor
Fixed airline miles are vulnerable: airline programmes change redemption charts, devalue Avios or miles, and add fuel surcharges that can make "free" flights surprisingly expensive. The safest long-term strategy is to accumulate transferable points currencies that can be moved to multiple airline programmes.
In the UK, American Express Membership Rewards points transfer to British Airways Avios, Aer Lingus, Air France/KLM Flying Blue, Singapore KrisFlyer, Emirates Skywards, and others. This flexibility preserves optionality if one programme devalues. The American Express Preferred Rewards Gold (free for the first year) earns MR points and awards 20,000 welcome bonus points after meeting a spend threshold.
In the US, Chase Ultimate Rewards (via Sapphire products) transfers to United, British Airways, Air France/KLM, Singapore, Hyatt, and others. Amex Membership Rewards transfers to Delta, British Airways, ANA, Singapore, and more. These transferable currencies are the foundation of sophisticated points strategies.
Travel Insurance as a Hidden Benefit
For travellers booking significant international trips, the travel insurance packaged with premium credit cards can represent substantial value. American Express Platinum (UK and US) includes comprehensive travel insurance: medical evacuation up to $1M, trip cancellation up to $10,000, lost luggage coverage, and travel accident insurance. The annual fee (£650 in the UK, $695 in the US) is high, but the insurance coverage alone can offset a significant portion for travellers who'd otherwise buy standalone policies.
More modest options exist: Barclays Travel Plus and various HSBC travel cards include basic travel insurance at lower annual fees. The key is to verify exactly what the coverage includes — specifically whether medical expenses, trip cancellation, and delayed departure are covered, and what the claim limits and excess amounts are.
What to Use for the Flight Booking Itself
The optimal setup for most UK travellers booking international flights is: 1. A no-FX-fee card with points earning for the flight purchase itself (Section 75 protection plus points) 2. A no-FX-fee debit card (Starling or Chase UK) for in-destination cash and small purchases 3. A travel insurance policy or premium card that covers trip cancellation and medical
For US travellers, Chase Sapphire Reserve is the most complete single-card solution: no FX fees, 3x points on travel and dining, excellent travel insurance package, Priority Pass lounge access, and a $300 annual travel credit that effectively reduces the net fee.
The Interaction with Flight Price Comparison
One final point worth making: the card you use interacts with where you find the fare. If you're using a cross-market fare comparison tool like RegionFare to find a flight booked through an international booking site (for example, a fare priced more cheaply in the German market), check whether your credit card will levy a foreign transaction fee on that booking. Many standard UK credit cards will — the booking may be in euros through a German site, triggering the FX fee. Using a no-FX card for such bookings is essential to capturing the full saving from cross-market price arbitrage.
The best travel credit card strategy is simple: never pay foreign transaction fees, earn points on every flight purchase, and ensure you have robust travel insurance coverage. The details of which specific card achieves this are secondary — the principles are what matter.
