In the case of AED it does not matter as it is pegged to USD just like the HKD does. So the fluctuation is very minimal.
Though when Chase runs a travel credit on the CSR it uses a screwed way to do the exchange rate - I used the CSR to buy the Dubai Transit's Nol card and load funds to it as needed. Chase system recognizes it is travel (commuter train I suppose) and credits back each purchase as it posts because I have not used up my annual $300 travel credit yet.
The exchange rate on the charge part looks a normal process, like AED to USD. However on the credit side, I could not figure it out how its system does based on the description and the exchange rate, but the USD amount is identical as the charge.
