I have sort of the opposite issue ... I'm a resident of Switzerland and have no residency in the US. I don't regularly check different rates, but didn't find any differences between the Swiss and the US rates when I occasionally checked the rates.

However, and this is my real issue, Budget now also starts charging me in CHF rather than USD when I rent a car in the US. I wouldn't mind if the exchanges rates weren't outrageous ... but because they are, I do actually mind (the "surcharge" is usually between 10 to 15 percent against the normal credit card rate). I can see USD rates on budget.com, but once I push the reservation button all goes into CHF. I can't find any way how I can get a quote in USD unless I wrongly specify my residency as the US.

Any help with this exchange rate issue?
