When booking online, you are normally quoted the amount payable in the currency that is used in the country of departure. For example, UAE Dirham if the flight is departing from Dubai, UK Pounds if departing from the UK.
We do offer a choice of other currencies if you are paying by Visa, MasterCard, Amex, or Diners. Please be aware that if you choose to pay in a currency that is different from the one in which your credit card issuer bills you, your credit card issuer will use its own exchange rates and may also apply foreign transaction fees. Unfortunately, Emirates has no control over your card issuer's exchange rates or fees.
