Price FX (FX = “foreign exchange”) is a foreign exchange rate tool that bypasses the all too common pitfall of high airline exchange rate fees that customers are charged when they pay in their preferred currency.If you pay on an airline’s website in a currency that the airline doesn’t use, your money will go through a foreign bank — a bank that operates in the airline’s primary currency. When this happens, there is usually a cost to cover the conversion of your money through the bank. Price FX, however, means that when you book with Kiwi.com in your local currency, regardless of what an airline is charging, we will only ever charge you exchange fees based on the middle of the market rate.
