When you pay for a flight, the price is set not just by the ticket but by the currency and your card's fees too. Choosing a different currency for the same ticket, or an unseen card fee, often adds $8-25 to the final total. This guide explains how to pay smartly and avoid paying more than you should.
💱 Which currency should I pay in
Many airline and aggregator sites offer the same ticket in several currencies — your local one, euros or dollars. The rate isn't always identical: sometimes the site's "local" currency is slightly more expensive than the airline's base currency.
The rule is simple — compare the same ticket's price in two currencies and pick whichever is cheaper for your card. Comparing a small fare won't save much in a few minutes, but on an expensive ticket the difference is noticeable.
If your card and the site both offer the same currency — compare first anyway. Often euros or dollars give a more realistic rate than the site's own conversion.
⚠️ DCC — the most common trap
Dynamic Currency Conversion (DCC) is the offer to pay "in your card's currency" on a foreign site or terminal. It looks convenient, but the rate is almost always against you and adds 3-7%.
When buying a flight, if the site asks whether you'd like to pay in your home currency, decline and choose the ticket's original currency (EUR, USD, TRY). The same rule applies at ATMs and shops abroad — details in the currency exchange guide.
"Pay in your home currency" on a foreign site — almost always a poor rate. Always choose the ticket's original currency and let your bank handle the conversion.
🏦 Card fees and fintech cards
Paying in a foreign currency with a local card, your bank often charges a 1-3% conversion fee. For a frequent traveler this adds up over time. This is exactly where cards like Wise and Revolut help — they use the real interbank rate and make paying for a ticket in a foreign currency cheaper.
- Check your card's conversion fee in your bank app — it's often 1-3%
- A multi-currency card (Wise, Revolut) — pay for the ticket in euros or dollars at the real rate
- Buy the ticket on the airline's official site or a trusted aggregator, not a suspicious link
- For hidden add-ons (baggage, seat) see airline ancillary fees
🧮 Calculating the true final price
A cheap base fare often gets expensive at the end — baggage, seat selection and the currency fee are added separately. Before you hit "buy", add ticket + baggage + card fee into one total, and only then compare options.
The same flight may appear in different currencies on two sites — you'll only know the real price by comparing final totals. To compare flights and dates, use the Travel365 flight search.

- Pay in the ticket's original currency — decline DCC (paying in your home currency) on foreign sites
