Do I pay the Butterfield / AAdvantage® MasterCard® credit card bill in Bermuda or US Dollars?
You can choose which currency you would like to use. If you have a source of US funds, it makes sense to pay in USD because you will not pay any FCPT or foreign exchange fees on purchases in USD. If you pay in Bermuda dollars, the FCPT and foreign exchange charges will be included in your balance. However, any purchases made in Bermuda dollars will not incur these fees.
