flydubai fixes a standard corporate book-keeping exchange rate on the 1st day of the calendar month for over 100 currencies against the UAE Dirham (AED).
The exchange rate is fixed based on varying factors such as the IATA published rate, Civil Aviation published rate, spot-sell rates published by independent banks/analysts, price indices and economic outlooks (including but not limited to political situations, leading and lagging indicators, fiscal and monetary policies of countries affecting the flydubai network), averaged out from the preceding month.
The rate remains the same until the end of the month.
