The trick of changing the currency on Airbnb to avoid DCC doesn't work anymore. Once I entered my card details I got a dialog saying "This is a US card so it'll be charged in USD" and I wasn't given an option to change it.

I disputed it with Chase, Chase said "it seems like your card is charged by a US merchant, so even if the stay is abroad, DCC rules don't apply to them". Any thoughts here?
